1 Release Notes for 2016 Season 2 [ ] Welcome to 2016 Season 2! This release features a whopping FOUR new vehicles: Audi R8 LMS GT3, Formula Renault 2.0, Mercedes- AMG GT3, and Mazda MX-5 Cup. Try them all and find out which one is going to be your favorite! With this release we are also launching a few brand new systems to further enhance your sim racing experience. We have added a DirectX 11 mode for the Sim to streamline the rendering process and reduce the CPU bottleneck inherent in our complex scenes. The Dynamic Tire Debris Accumulation system will actually show you in real-time what's sticking to your tires based on our physics calculations and the Dynamic Track. We have also expanded our horizons, literally, and are proud to introduce the Time of Day feature including both Morning and Late Afternoon as options on all tracks and race modes. We have enhanced our Netcode with an option for greater bandwidth, allowing more information to pass between you and our servers. A new easy-to-use video capture tool has also been rolled directly into the Sim with this release. Also, our vehicle audio, including engine sounds, tires, gear shifting, and much more has been made even more realistic with this release. All of these systems help to enhance our realism and raise the bar on what you can expect from the quality of your favorite racing simulator. We hope you enjoy this release; see you out on the track! Website - Added the ability to select the time of day to drive in Test Mode and Hosted Mode. Results will also now show the time of day for the session. - All pages that reach into the backend for stats are sped up significantly. - The My Series Results page has been rewritten and optimized; it should be much more responsive now! - Hosted Sessions should now remember the correct league selections when editing. - The modal window that appears when you receive a gift is now sizing and building correctly. - The Replays page now features a message explaining how it works. - The All Teams page now requires you to search before displaying any results, which should expedite loading of the page. You must search with a minimum of 4 characters. - The Team Series Stats page will now only display Official Series. - Fixed places where Open Practices appear available as a joinable link, but should not be due to license restrictions.

2 - In the Team Registration modal window, Autofill will no longer input your address as your team name. - Pre-Driver Chat has been removed from Pre-Race. - Toned down the look & feel of the To-Do buttons across page headers. This includes yellow, red, green, and blue. Billing - Earlier last month, we added Paymentwall as an additional Payment Option for all of our customers. Paymentwall is a safe and secure way to pay for purchases made within iracing. Paymentwall allows you to pay with a wide range of local payment options and currencies, so that you may choose the most convenient method for your purchase. These payment options include Gift Cards, Mobile, Prepaid Cards, Bank Transfer, and various local options for your country. Paymentwall offers the highest level of security and is trusted by over 150 million users worldwide. Updater - The iracing Updater will now ensure that it has updated itself before checking and/or installing MSVC, DirectX, EAC, and D3DGear. This could have caused the self-update process to time out and not complete the update for some people. Paint Kit - Virtual Racing School sponsor added. - iracing logos have been updated to a newer version. - The Inside Sim Racing sponsor has been updated. Simulation - Substantially reduced the time required for the simulator to exit. - If a race server rejects your attempt to connect to it, it will now provide a more helpful message explaining why, instead of a generic messages about your connection being closed. Race Control - Fixed a bug where racers would only be allowed up to 8 minutes to finish their lap after the leader finishes a race. This should enable racers to complete their final lap on tracks with longer configs. - Fixed an issue where sometimes incident limits were being reported in sessions which did not actually have incident limits. Dynamic Track

3 - Marble creation rate has been roughly doubled. - Fixed an issue where marbles were getting cleared from oval tracks during cautions even when the "Automatically clean marbles" option was disabled. Netcode - Two new Connection Type selections are now available on the main Account->My Account page, under Preferences. These selections allow higher network bandwidth usage between the simulation and the race servers. Mostly, this allows the server to send more detailed data for each opponent car and/or more opponent cars to the simulation. If your computer, graphics card, and Internet connection are all fast enough, and you select one of these new options, you ll likely also want to adjust the in-sim Options->Graphics Max Cars setting to take advantage of the extra allowed bandwidth usage. Garage - Initial temperatures of wheels and tires have been improved, especially for cars with tire warmers. Previously, the entire wheel and tire was heated to the tire warmer temperature; now only the tire surface is heated to the specified temperature, while the wheel is more appropriately closer to the ambient temperature. This may produce a subtle change in ride height in the garage, so cars with tire warmers may need an adjustment to pass Tech if they were close to the limit on ride height. Rendering - The "Two-Pass Trees" rendering option is now functional on ALL tracks. DirectX 9 - Added a new option to the "renderer.ini" file named, ReduceCockpitFlicker, which is enabled by default. This option reduces the z-fighting and flickering between objects that can sometimes be seen in vehicle cockpits while racing at very large tracks. - Fixed an issue with the rendering of fog over the Dynamic Track, which occurred when rendering the Dynamic Track as a separate pass via the setting in the renderer.ini file. - The flare intensity of headlights has been reduced during the daytime. - Fixed several issues with physically based rendering at night tracks. - Fixed an issue with shadow maps that caused some of them to periodically render using incorrect texture sampling. DirectX 11 - A preliminary beta version of a DirectX 11 based version of the Simulator is now available for testing and is provided via two additional executables, a 32-bit version named iracingsimdx11.exe, and a 64- bit version named iracingsim64dx11.exe. You may select to use either the DirectX 9 or DirectX 11

4 version, as well as choose between the 32-bit or 64-bit version of the Simulator using the Settings page of the member site. We recommend using the 64-bit version if possible. - The Graphics Options settings for the DirectX 11 version are stored separately from those for the DirectX 9 version; they can be found in the rendererdx11.ini file. This file will be created automatically after launching the DirectX 11 version of the simulator for the first time, which will also initiate the autoconfiguration process. - The configuration options for the DirectX 11 versions, including the resolution and refresh rate as selected during the auto-configuration, are stored in a new section of app.ini file named, [Graphics DX11]. - Please note that when setting up any application overrides in your GPU s device driver s settings to take care to set them for the correct executable name(s). PopcornFX - The color of debris and dust is now tinted based upon the surface from which it was gathered. - Increased the accuracy of the tire widths for debris related positional effects. - Enhanced the accuracy for position and velocity offsets of particles. - Grass debris particles now have a greater size variation. - Dust particle velocity has been improved. - Fixed an issue with smoke being lit incorrectly at night. Audio - New tire roll, scrub, and skid sounds have been added. - Updated all vehicle shift sounds and tuned volume levels. - Engine sounds will transition smoother between loads and throttle changes. - All vehicles now make gear shifting sounds that are audible both inside and outside of a vehicle. - Tires will now make sound when spinning while the car is stationary. - Updated the audio frequency of rumble strip and curb sound effects. - Fixed an issue where the sound buffer was not getting properly cleared while the Sim was shutting down, sometimes causing an annoying looping noise. Opponent Cars - Smoke and debris generated by opponent vehicles can now be seen.

5 - Opponent vehicles now show wheelspin and lockup, and skids and smoke from these actions are more realistic. - Fixed a bug that was causing distant opponent cars to appear to have minor systems malfunctions; such as the DRS wing twitching, or pit limiter lights blinking. Dynamic Tire Debris Accumulation - Tires on all vehicles now visually show the accumulation and dispersal of debris. This includes materials such as grass, gravel, rubber marbles, dust, and sand. These materials are picked up when driven over based on the surface type, grip, and speed of the vehicle, and then they are removed over time by the same factors. The physics model for this activity has already been running since last season's update, so there is no change to driving characteristics, but now you can see the effects! Vehicle Headlights - We have added the ability for some of our cars to flash their headlights. Sports cars use this ability to notify a driver in front of them that they are about to attempt a pass. Mapping the function to a button will allow the headlights to flash on and off several times each key press. The cars that have been updated to utilize this new ability include: - - Aston Martin DBR9 GT1 - - Audi R8 LMS GT3 - - BMW Z4 GT3 - - Chevrolet Corvette C6.R GT1 - - Chevrolet Corvette C7 Daytona Prototype - - Ford GT GT3 - - HPD ARX-01c - - McLaren MP4-12C GT3 - - Mercedes-AMG GT3 - - Riley MkXX Daytona Prototype - - Ruf RT 12R C-Spec - - Ruf RT 12R Track Time of Day

6 - When creating a race you are now able to set a Time of Day parameter which includes two additional options beyond the traditional Afternoon and Night; Morning and Late Afternoon. Both new selections adjust the position of the sun in the sky, and affect the race just as this would in real life. This feature is available for all tracks and in all session modes. Pit - Lollipop Guy has received an animation overhaul, and will appear much more realistic! Video Capture - A new video capture system has been added to the Sim based on the D3DGear capture engine. By default, the hotkey "Ctrl-Alt-Shift-V" will toggle video capture on and off. Video is saved to the [documents]\iracing\videos\ folder. - By default video is captured at 720p and 30 fps using the WMV video container. You can change the default video quality and format by editing the [Video] section of the "app.ini" file. - Unfortunately, the Windows 8 and Windows 10 Metro Player cannot load video for Windows codecs, so the video captured by this tool will need to be played in Windows Media Player or a third party video player. - Windows Media Player (WMP) cannot handle the AVI2 (OpenML) file format. This format allows AVI files to grow beyond the 2 GB file limit. You will need to use a third party player such as Video LAN Player (VLC) or MPC-HC. - A new screen capture system has also been added along with the video capture feature. By default, hitting "Ctrl-Alt-Shift-S" will save a screenshot of the sim to [documents]\iracing\screenshots\ folder. - Due to a limitation of our control handling code we cannot trigger a screenshot or toggle video capture when a dialog is opened. This effectively makes it impossible to take a screenshot of the garage or settings dialogs. However, you can get around this limitation by starting to capture video before you enter the Garage or other options screens and then stopping the video capture once you exit that screen. We are looking into ways to work around this limitation. - You can disable the loading of our video capture module by setting "videocaptureenabled=0" under the [Video] section in the "app.ini" file. Replay - Fixed an issue where opponent vehicle wheels would appear to rotate incorrectly when viewing replays frame-by-frame, or rewinding. Macros - Text chat macro speed is no longer limited when applying a pit or admin command. Now users can use "#fuel +1g$" to increment fuel in their tank without waiting a second between button presses!

7 Telemetry - Legacy telemetry (NR2003 Telemetry) is now disabled by default. It can be turned on again in the "app.ini" file by adjusting the "enablelegacytelemetry=1" option. This interface is deprecated and will be removed from the sim next season. - Session times are now reported with 4 decimals of precision. ARX - Examples have been updated. - Fixed an issue with ios where the UI would zoom when the app was rotated to landscape. - ARX can now handle automatic unit conversions using either a string type or an offset/scalar pair. - ARX data transmissions are now limited to 10 times per second to prevent overload. ATLAS - The ATLAS Installer has been updated, and it now fully automates the process of configuring ATLAS to work with iracing ".ibt" files. - A new Quickstart Guide has also been added to the ATLAS Installer. Oculus Rift - Fixed a bug where night track shadow volumes were rendering incorrectly in one eye. Peripherals - Fixed a potential crashing issue while Force Feedback is enabled in a 64-bit operating system. CARS Aston Martin DBR9 GT1 - This vehicle is now capable of flashing its headlights. - Updated tire sounds. Audi R8 LMS GT3 - New car added! - The Audi R8 LMS GT3 ranks among the most successful GT3 cars with more than 200 international wins in events such as the Bathurst 12 Hours and Nürburgring 24 Hours, along with back-to-back championships in the 2014 and 2015 Blancpain Endurance and Blancpain GT Series. In contrast to its allwheel drive road going version, the R8 LMS GT3 is built by Audi Sport and quattro GmbH to comply with

8 the rear wheel drive only GT3 regulations. However, the superb balance and impressive power to weight ratio of the R8 LMS GT3 have made it a winner in virtually every series in which it's competed. - This vehicle is capable of flashing its headlights. BMW Z4 GT3 - Season setups have been added. - Braking performance during big slides has been improved by altering the ABS slip calculations. - TC algorithm updated to use a mix of longitudinal and lateral slip to cut throttle.

9 - Body panels may now be fully repaired during optional repairs. - When the front clip is heavily damaged, the pit crew will now replace the whole nose during a pitstop. This replacement takes approximately 2.5 minutes (they also have to swap the radiator and other mechanical parts), but does not show up as a repair countdown timer in the UI, so be patient if the stop appears to be delaying and you'll get a shiny new nose soon enough. This should help with the errant black flags for damage that this car is known to generate. - This vehicle is now capable of flashing its headlights. - Updated tire sounds.

Your current car setup is now being logged to telemetry, both to the live telemetry that external tools can access and it is appended to the end of the disk based.ibt telemetry file. For the most part this is a good thing, but if some reason you are worried that someone will use this to gain access to your setup you can turn off this behavior by setting app.ini [Misc] irsdklogsetup=0. So in summary, your car setup is now buried in every telemetry file you capture, so when you share a telemetry file you are potentially sharing your setup as well. Release Notes for Jan 7 Update [ } Here is another small follow-up to our 2016 Season 1 Release. We've fixed a few more issues. Rendering - Improved the graphics autoconfig to set the "Video Memory to Use" limit to precisely 10% less than the dedicated video memory of the GPU, rather than always 128MB less at most. - Replaced the graphics option, "Cap Frame Queue," with a more useful version, "Max Prerendered Frames," adjustable from 1 to 4 frames. Typically you should set this value to the number of GPUs in use for rendering, in most cases this is 1, but for SLI or Crossfire this is often 2. Setting the limit to zero frames disables this function completely, which is not advisable since it will lead to increased control lag, or in some cases stuttering. This new setting defaults to a value of 1, and is named "MaxPreRenderedFrames" in the "renderer.ini" file. - A new setting, "ParallelSorting=1," has been added to the "renderer.ini" file. Changing this setting to 0 will disable the use of multi-threading during scene sorting in the renderer. The multithreading optimizations are enabled by default. - Fixed an issue where textures were only loading after entering the garage screen when the option "LoadTexturesWhenDriving" was set to zero in the "renderer.ini" file.

24 Shared Pit Stalls - Sessions will now be split into run-groups based on the number of starting grid stalls at the track, instead of the number of pit stalls. Telemetry - A new telemetry item "LapCompleted" has been added which contains the number of laps completed by your car (Similar to "Lap" which contains your car's currently started lap). At a circuit event, "CarIdxLapCompleted" will always be 1 less than "CarIdxLap", since the finish line both finishes one lap and starts the next. But at the Nürburgring Tourist config, where the start and finish are separate, completing a lap does not start the next one. - A new telemetry item "CarIdxLapCompleted" has been added which is an array containing the number of laps completed for each CarIdx (Similar to "CarIdxLap" which contains the currently started lap). - Telemetry items "LapDistPct" and "CarIdxLapDistPct" have been updated to export "0.0" to "1.0" correctly for the Nürburgring Tourist config, with "1.0" being at the finish line. The number will continue to increase above "1.0" in the non-timed area, and wrap back to "0.0" at the start line. - The state of "TrackCleanup" has been inverted. Now a value of "0" indicates that the track is not being cleaned up, and a value of "1" indicates the track is being cleaned up. - Renamed several telemetry parameters to remove the unacceptable characters, "-" and, " ", as follows: - - PowerMGU-K = PowerMGU_K - - TorqueMGU-K = TorqueMGU_K - - PowerMGU-H = PowerMGU_H - - EnergyBatteryToMGU-KLap = EnergyBatteryToMGU_KLap - - EnergyBudgetBattToMGU-KLap = EnergyBudgetBattToMGU_KLap - - DRS Status = DRS_Status McLaren MP Fixed an issue where DRS lights were not activating correctly when the control screen was active. Radical SR8 - Fixed an issue where the left side mirror was not being deformed correctly when damaged. Silver Crown

25 - Changed the weight jacker from 5/8" throw to 1.25" throw. This change means each click will have double the cross weight change compared to before. Super Late Model - Vehicle setups have been updated. Circuit de Spa-Francorchamps - Removed erroneously placed pit boxes. Nürburgring - Qualifying laps that begin directly from the Tourist exit on Nordschleife and Combined configs will now correctly score the first flying lap. - Fixed some issues with object collision on the left side of the Tourist pit lane. Release Notes for Dec 22 Update [ ] Here is another small follow-up to our 2016 Season 1 Release. We've fixed a few more issues to make your racing experience even better. Rendering - The rendering cutoff distance for track surfaces at most tracks has been increased by 1km. - Improved the graphics autoconfig to set the "Video Memory to Use" limit to approximately 128MB less than the dedicated video memory of the GPU, rather than to the full amount dedicated video memory. This is because Microsoft Windows uses a portion of the video memory for itself, leaving even less for the simulator, especially in newer versions of Windows. The first time the simulator executes, your existing video memory setting may be automatically lowered to this new setting if it was set too high. Please do not increase it, as it will only lead to performance issues and stuttering. The setting in renderer.ini has been renamed from "VidMemMB" to "VideoMemMB" to help facilitate this change. Scoring - Fixed a bug that was causing official multi-class series with embedded qualifying to fail to reorder the starting grid to keep all cars in a class gridded together. McLaren MP DRS Status can now be seen in telemetry. The variable has four possible values: = Inactive

26 - - 1 = Available in Next Zone = Available and in a DRS Zone = Active - DRS can now be used for Lone Qualifying. - A low oil pressure warning will now trigger the dashboard to enter a failure mode when the engine lets go. - Fixed an issue where Control Setting changes where not appearing in the display. - Fixed a bug that was allowing Spotters and Crew Chiefs to adjust the diff preload control in the F8 Black Box. Nürburgring - Added a large speed limit sign, portable toll booth, and cones for the length of the straight alongside the pit lane on the Tourist config. Release Notes for Dec 16 Update [ ] Here is another small follow-up to our 2016 Season 1 Release. We've fixed a few more issues, and added in a few more balance tweaks. SIM - Fixed an issue that reduced the maximum number of car positions transmitted to you by the server, causing fewer than the actual number of cars to be displayed. Rendering - Improved the Level of Detail selection of the track surfaces for very wide fields-of-view in three-screen mode. Previously, the side monitors could render distant portions of the track at a higher level of detail than necessary. - Added the ability to limit the number of track surface decals rendered from the cockpit cameras. These limits can be specified in the renderer.ini file. The MaxTrackDecalsInCockpit setting is for the driver s view, and the MaxTrackDecalsInMirrors setting is for the driver s view in the mirrors. Because track surface decals are rendered in clumps, try adjusting the settings using increments of about 150. If any portion of a clump would render, the entire clump will render, so the limit input may be slightly exceeded. All decals very near the camera will render even if the limit is exceeded to avoid very obvious

27 popping in of the decals. Mirrors will only render track decals when the Higher Detail Mirrors setting is enabled in the Graphics/Replay options screen, which will negatively affect performance. Opponent Cars - Fixed an issue where the tires of opponent cars would wobble, causing smoke. Telemetry - Several values have been added for better monitoring of the McLaren MP4-30, including: ERS Battery Charge, Power from Battery to MGU-K, and Power from MGU-K to Battery. McLaren MP4-12C GT3 - Fixed an issue where a second steering wheel could be seen in the external model. NASCAR Sprint Cup Chevrolet SS - Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter. NASCAR Sprint Cup Ford Fusion - Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter. NASCAR Sprint Cup Toyota Camry - Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter. Star Mazda - Downforce has been increased in response to feedback from a real-world driver. - Diff locking has been reduced from 10% to 3%. - Tire grip has been increased slightly. Release Notes for Dec 14 Update [ ] Here is a small follow-up to our 2016 Season 1 Release. We've fixed a few issues, and added in a few more balance tweaks. Rendering - The "Draw Car First" option is disabled for now due to some potential problems.

28 - Fixed a bug in the vertex compression that caused at least one car to appear dented and may have been responsible for more serious issues. PopcornFX - Fixed a bug in the particle system that may have caused missing particles, crashes, or hangs, especially at Nürburgring. Aston Martin DBR9 GT1 - Fixed some PBR shader issues. Ford GT GT3 - GT3 BoP Update: Aero drag has been reduced slightly. Ford Mustang FR500S - Updated baseline setup. McLaren MP4-12C GT3 - GT3 BoP Update: Minimum weight has been reduced by 10 kg. McLaren MP Added new assignable controls to the Sim for use with this car: Peak Brake Bias, Diff Preload, MGU-K Re-Gen Gain, MGU-K Deploy Mode Toggle, MGU-K Deploy Fixed, MGU-K Deploy Adaptive. - The "Push To Pass" control is now called "Push To Pass / Overtake" since it operates the Overtake function on this car. - Deploy Mode is added to the wheel display. eg: A03 means Adaptive mode (Setting 3), F06 means Fixed mode (Setting 6). - The deployment rate of the MGU-K can now be configured by the driver. - There are now some MGU telemetry channels available for logging. - Replace the baseline.sto with the high downforce setup rather than medium downforce setup. - The shift light RPMs for Logitech G27 wheels have been properly tuned for this car. - Lap Time and Current Delta display items are now labeled correctly. - Fixed several issues with the MGU-K deployment.

Release Notes for 2016 Season 1 [ ] iracing.com is proud to release our 2016 Season 1 Update! Prepare yourselves for the excitement of getting behind the wheel of the McLaren MP4-30, and racing on the legendary Nürburgring and Southern National Motorsports Park tracks. We also have a host of other updates and tweaks to help keep iracing the world's best racing simulation. We'll see you out on the track! Special Notice: After installing the update, please go into your graphics settings for the Sim and disable the "Render Car First" option. It is presently causing graphical issues on many tracks. We will release a small patch soon to fix this issue. Thank you. Website - Vehicle icons have been added to the Team Series Stats page, and show the breakdown of cars for teams in a specific series. - When hosting a session that is not a race, the open pit stalls for the track may be extended, allowing more racers into the session. These extra racers will use shared pit stalls.

31 - You can now easily refer friends to join you on iracing by using the Refer A Friend! section of the My Account page. - The Ping window now shows IPv6 addresses (where available), and a toggle has been added to the Settings panel to enable an IPv6 connection preference in the Sim. - In Test Mode, the At Night checkbox will now remember its prior state. - All "Share on Facebook" links have been removed. - The Regional Stats and the Dashboard pages have been removed. - Fixed an issue in the extended descriptions for Hosted Sessions where the Weight Penalties were listed as undefined instead of a value. - Fixed an issue where the "tournament editing" screen sometimes became unusable. - Fixed several issues with the "join a team session" screen. - Fixed an issue that was causing car information to display incorrectly in the "More Info" section of the What's Hot page. - Fixed an issue that was causing an incorrect amount of content to be reported as being owned by a user. Billing - Fixed an issue where the confirmation box for purchasing a new league was not reporting the correct cost. Paint Kit - A safeguard against paint schemes being reset to the default white has been implemented. Data - Old session detail data will be archived beginning with this release. With the archiving, drivers will still be able to go all the way back in their history to see the overall results of a given event. Since we have chosen a 3-year window to start with, then prior to 2013, drill downs to lap charts and lap times will no longer be available (the page will be blank). In addition, hovering over the results link of a given session will only show the split that the selected driver was in. It won t show all splits for the event. Overall statistics will remain the same. Simulation - Support for IPv6 has been added to the Sim, and the Race and Ping servers. You can state a preference for using IPv6 over IPv4 if it appears that your computer has IPv6 connectivity. If you enable the IPv6 preference but either your computer does not appear to have IPv6 connectivity, or the race server you

32 join does not advertise that connections to it are available on IPv6, the Sim will fall back and connect using IPv4. If both ends say they support IPv6, and you have stated the preference to use IPv6, the Sim will only attempt to connect to the server using IPv6. If for some reason that fails, it will not re-try using IPv4. You can tell which protocol was used to connect to the race server by invoking the Latency control (by default this is bound to the "L" key). The ping/quality message will tell you which protocol the Sim used to connect to the server. - Fixed an issue where sometimes racers were unable to join a race as part of a team if they had previously been connected to the same race as a spectator. Dynamic Track - Marbles on the track are now immediately influenced by both the player car and opponent cars to better simulate the effect of following a car closely through debris. - Debris will collect on tires of the player car and then be flung off when appropriate. This means tires will continue to emit grass, gravel, dirt and marbles even after leaving the associated surface. - The in-sim Info tab now displays actual average race-line temperature at the start of the session as the track temperature, to simulate a crew member taking some sample measurements with a temperature gun pointed at the track a few minutes before the session begins. - Improved the way the server broadcasts the track state by allowing it to adjust what it sends depending upon the current situation on a per-client basis. - Improved performance when the dynamic track is not being rendered by removing some unnecessary code. New Netcode - We have implemented some new netcode that sends more data to and from each car. This allows us to utilize more information for each vehicle, such as the pit limiter status for all cars that use pit limiters, and the DRS wing state and ERS warning light for the McLaren MP To help account for the additional data that can be sent for each car, the amount of network bandwidth that can be used for sending data from the server to the simulation has been increased by about 12% to 108kbits/sec for the 128K or faster connection type selection, and by about 9% to 142kbits/sec for the 256K or faster connection type selection. See the Preferences section on the Account->My Account page to select your connection type. Garage - Cars with tire warmers will now use the tire warmers while in the garage. The "Cold Pressure" setup item is now renamed "Starting Pressure" to reflect this change. iracing setups have been adjusted for
