iRacing tyre (tire) model and information
2016s4 from iRacing release-notes 
  • Brake bias adjustment is now also available in Fixed Setup Series to a small host of vehicles.
  • Your experience at night tracks has been improved with the new Dynamic Night Shadow Maps system,
    and every vehicle windshield has been improved with realistic reflections.
  • A new character model has taken the driver's seat and is also positioned in the pits,
    and you should start to see wind-animated flags appearing at race courses.
  • We are also launching preliminary support for OpenVR / HTC Vive headsets, and antialiasing in our virtual reality views.
    All of these along with a host of setup updates, bug fixes, and other enhancements are here for the 2016 Season 4 Release.

    iRacing has broken links to old articles & their
  • ANZ iRacing series thread. (Started 2016s2).
  • LQSPF PDF of FAQ FPS black box: (L)atency (Q)uality (S)kew (P)age fault. (F)orce feedback.
    You can also enable CPUMeter=0 in app.ini which displays as C. (See App.ini for more).
    Information from post:
    The CPU meter measures only the CPU usage of the simulation's real-time thread (the one that runs the simulation, basically).
    Gray is the 1-second trailing average CPU usage.
    Purple is the 15-second trailing average CPU usage (only visible if it's higher than the gray bar).
    R is for rendering thread CPU time
    G is for GPU rendering time
    From 2016s1 release notes:
    Two additional bars have been added to the "Comm" UI when “CPUMeter=1” is enabled in "app.ini" file.
    There is now an "R" bar which is the time the foreground/Renderer took and a "G" bar which is the time the GPU took.
    There is also a new option in the "app.ini" file named “CPUMeterAsText=1” which will turn all the "CPU" timing related meters into text that reports the times in milliseconds.
    From post: The bar is calibrated to be 60fps. If it doesn't turn red you are getting 60fps or better.
    The units are in milliseconds. Which means anything less than 16.6ms will be 60fps or better from the GPU's view.
    From 2016s4 release notes:
    The Q-Bar on the frame rate/connection status meter area now has two side-by-side meters.
    The original value is in the left-hand bar, and shows the amount of packet loss from the race server to the simulation.
    The new right-hand bar (which grows from right to left) shows the amount of packet loss from the simulation to the race server.
    Note that the data for this right-hand bar is sent from the server to the simulation, so if there is a sudden loss of all packets sent by the server to the simulation, the value in this bar will not update.
    As before, each bar becomes full at 50% packet loss, though each is now about half the width of the original Q meter.

    iRacing's Graphics configuration wizard, for new installs and trouble shooting Removed 2015s2.
    iRacing's wheel/pedals configuration wizard, for new installs and trouble shooting Removed 2015s2.

    ** Calibrating pedals / wheels is still possible in sim options within a session.

    Tip: leave H pattern in neutral when configuring/mapping unless instructed otherwise.
    Tip: don't use the clutch when instructed to select a gear.

    2015s3: "a button to launch the graphics config has been added to settings panel."
    Also added drop-down dialog to choose display adapter.
    Click on Settings > Run Graphics Config > Select display adapter > Auto Configure or Minimum settings
    I regularly copy iRacing root files from documents/iRacing/ to somewhere safe

    Before 2015s3... work-around post by Susan F (iR Staff):
    - Method 1: rename (or delete) app.ini and renderer.ini located in Documents/iRacing folder
    I suggest renaming so you don't lose any edits - you can compare contents later.
    The next time you launch the sim, it should prompt you to reconfigure your graphics.
    - Method 2: Edit file Documents/renderer.ini, change AutoCfgCompleted=1 to =0
    The next time you launch the sim, it should prompt you to reconfigure your graphics
    - Method 3: Via CMD prompt > cd c:/ > ENTER > cd program files (x86)/iRacing > ENTER > iRacingSim64 -autocfg

  • joyCalib.yaml now has wheel/pedal calibration data. My own joyCalib tweaks.

  • Tip: Improve driver input; turn tyre sound up in options. options-screenshot.
  • joyCalib.yaml now has wheel/pedal calibration data. My joyCalib tweaks.
  • app.ini located in documents/iRacing/app.ini has many settings to tweak.
    Before editing app.ini, ensure sim is closed and backup the original file.
    My app.ini page notes more settings at the bottom of page.
    * Hear sim when tabbed out: "muteWhenFocusLost" set to 0.
    * Black box position: [Drive Screen] "UIOffsetBottomPct=0" adjusts black box position on screen.
    * Roll effect: "DriverHeadHorizon"; forum thread.
    * Yaw: DriverRotateHead; forum thread.
    * DriverHeadNoPitch setting to detect elevation changes and DriverHeadWobble setting.
    * Seat height; (driverHeightAdj) moved to Camera-UI as it's not necessarily needed (2014s2 update).
    * "enableHotPlug" to turn off auto detect new usb devices for unstable enviroments
    * "debounce" added to fix sequential double shifting. (More notes on my G27 page).
    * "carLowHiPadding=0.25" adjust car gap in meters before spotter calls clear.
    * steeringFFBSmooth to reduce FFB chatter - more info in my FFB and G27 pages.
    * Interesting view related thread with comments from David Tucker.
    * David Tucker's post

    Posted 5/2016 by iRacing staff; David T:
    We use a fallback plan when looking for the files, we look in your local directory first, then in the local .dat file, then up a level as needed till we get to the spcc.dat file where the master samples are kept. You just need to decide if you want to override the tj and steve pack or the default pack or want to make your own.

    To modify tj_and_steve you place your new 15SECONDS.WAV into the sound/spcc/tj_and_steve/ folder and we will pick it up in place of the existing one found in the tj_and_steve.dat file. On the other hand you can name it 15SECONDS_2.WAV and use the spmsg.txt file to add it to the list of samples that get played, causing us to randomly choose between your sample and the tj and steve sample.

    If you want to make your own pack then put it in sound/spcc/yourPack/ and any samples you don't provide will fall back to the default recordings that Greg Hill made for us (found in the spcc.dat file).

  • Telemetry generic post:
    There is a Telemetry forum section and another for API's and Development discussions,
    A list of telemetry variables was out of date before it was finished - attached to post. (11/2015) For me: filed
    iRacing also has instructions for Atlas telemetry program in the Reference section.
    Some use Motec to read the data, some write apps, etc. iSpeed is all I use but not for pressures.
    - MoTeC Project 2015-Master-v6 by Peter C. - thread.  And a related thread (6/2015) with various links.
    2016s2 from release-notes 
    - 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.
    - 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 for some reason you are worried that someone will use this to gain access to your setup you can turn off this behavior by setting "[Misc] irsdkLogSetup=0" in the "app.ini" file. 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.

  • Switch to windowed mode MOD - thread.   For me: filed
    JSGME (JoneSoft Generic Mod Enabler) can be used to swap out your renderer.ini and app.ini files with just a couple clicks.
    This allows you to quickly swap between "painting mode" (iRacing in a window) and your normal settings (most likely full-screen).
  • Extract from post (March 2015)
