Easy Anti Cheat

iRacing has always invested significant time, energy and development effort into trying to stop “cheating”. There are many different types of cheating. In the last June build for example we installed software code to prevent on-track tire heating during qualifying for oval racing. Poor sportsmanship on track could even be construed as cheating as another example. However more often than not, the main concern for members are potential software hacks that essentially attempt to change the game in some way for the cheater’s benefit. In that regard, all of the prevention and detection code we have put in iRacing in the past was done by us internally. We never included any of that work in our release notes mainly for the obvious reason that we did not want to provide cheaters with any information.

However in our next quarterly software update (early September) our current plan is to include new cheat prevention & detection in the update and release notes for several reasons. Mainly because the new cheat prevention and detection comes in the form of a partnership and integration we did with a professional gaming anti-cheat company called Easy Anti Cheat. We are excited about this partnership as we have enhanced our ability to detect and prevent cheating significantly. The EAC system prevents cheaters from using several common methods to try to gain an advantage over other players. This includes things like: running the iRacing simulation inside a “sandbox”, to prevent external programs from hacking into and modifying the simulation as it runs; or modifying the iRacing installation files (cars and tracks) to gain an advantage; or replacing system level components used by the simulation with versions that include cheat hacks.

When applying this next build on a Windows computer, the installer program for the EAC software will automatically be run. On Mac OSX and Linux, the EAC software is able to operate without this explicit installation step. In all cases, the EAC software is only active on your computer when you are running the iRacing simulation software – when the sim exits, the EAC software exits, too.

If you launch the simulation and an issue is detected before the simulation has connected to the race server, a message describing the problem will be shown to you in a dialog box, and the sim will not run. If an issue is detected after connecting to the race server, a message describing the problem will be shown in the Chat Pad, and you will be disconnected from the server.

The error messages are intended to be sufficient to identify what caused the issue. But if it’s not clear how to resolve the issue, email iRacing customer support at support@iRacing.com to help get you back to racing. We will work diligently with you to correct any issues. However, we do not expect many issues as we have done extensive testing already. The most likely error to arise will be if you are using replacement versions of system libraries (d3d9.dll, for example) that are not already flagged as being innocuous. Since such replacement libraries could potentially contain hacks to enable cheating, they are not allowed unless they have been validated.

Splitting Multi-car-class Fields

The prior algorithm for forming splits for multi-class sessions attempted to ensure that as many splits as possible would be multi-class, down to some minimum number of drivers in each class within a split. This made for some not-so-great racing for drivers in classes where their split had this minimum number of drivers.

With this season’s build, we have implemented a new split-forming algorithm for multi-class sessions that instead attempts to ensure that all car classes are packed relatively evenly into the higher-rated splits, potentially at the expense of the lower-rated splits being devoid of one or more car classes.

The algorithm for choosing the overall field size for each of the splits is unchanged – each of the higher-rated splits formed for a session will have the same overall number of teams, with the lower-rated splits potentially having one less team. Since the higher-rated splits might “consume” all the teams in one or more of the less-used car classes, and since the lower-rated splits will still have the same overall number of teams, the lower-rated splits could thus have more teams in each of their car classes than the higher-rated splits have in those same car classes.

Session Splits

• We have added a new method by which sessions get split into run-groups. The earlier method typically chooses the “best” race server farm (US, Sydney, Amsterdam) based on the average ping time of all the registrants to the farms, and then splits the teams into run-groups based on iRating. The new method splits the teams into run-groups based on iRating, and then chooses the best farm for each run-group.
• Additionally, the new method tries to avoid assigning the group onto a farm if any of the drivers in the group would generally prefer to avoid that farm. In practice this will mean that if anyone in the run group prefers the Sydney farm, and anyone else in the run-group prefers the Amsterdam farm, the run-group will be assigned to the US server farm.

Dynamic Track

• The track surface is now dynamic, and models the changes in track rubber, marbles, and temperature. Track rubber is built up under the tires in rough proportion to how hard they are working. Tires generate marbles, and these can accumulate on tires and be thrown off and redistributed on the track. Temperature is variable across the track and is influenced by weather, the position of the sun in the sky, the surface angle of the track, albedo (color), track rubber, shadows, and interaction with cars.
• These variable aspects of the track affect the level and characteristics of tire grip available, and the wear rate. Generally, a rubbered-in but cool track free of marbles will offer the most grip.
• Initial track conditions can be specified for testing and private hosting sessions. The amount of running activity on the track prior to the session can be specified as a percentage, or left to be determined automatically based on the session type. The percent usage amount determines the level of track rubber and marbles at session start. In a multi-session event, each session can be specified individually to simulate changes to the track between sessions due to additional running or from an overnight rain, or a session may be designated to follow immediately and inherit the track state from the previous session. Marbles can be cleaned off the racing surface prior to the session, and also during yellow flags on ovals, or they can be left undisturbed.

Borderless Window Support

• The sim can now be run in windowed mode without a border or title bar. There is a new option on the auto-config dialog and a new graphics option to disable the border. Like the full screen toggle in options, the border configuration does not take effect until the sim is restarted.

Replay

• Add an app.ini setting [Replay] maxFramesToSearchPerUpdate=2048 setting to control how much tape is searched per update during a long search.

Telemetry

• Add support for fast repair to telemetry pit script commands.
• Log pending pit service request to telemetry as “PitSvXXX”. PitSvFlags is a bitfield defines in irsdk_defines.h as irsdk_PitSvFlags and covers all the check boxes.
• Log live weather to telemetry.
• Log the driver’s fuel tank size to session string as “DriverCarFuelMaxLtr”. Log the fuel restriction percent (if any) to session string as “DriverCarMaxFuelPct”. Multiplying both together will give you the true fuel limit for this session.
• Renamed “CarClassMaxFuel” to “CarClassMaxFuelPct” to better reflect the fact that it is a percent of the tank that you are allowed to use.
• Dump information about the current setup to the session string
  DriverInfo:
  DriverSetupName: path
  DriverSetupIsModified: bool
  DriverSetupLoadTypeName: [invalid|user|iracing|baseline|current|default|fixed|shared]
  DriverSetupPassedTech: bool
• Fix a bug where not all cars had a properly set carClassColor in a mixed class race.

Keyboard Macros

• Added a #fr fast repair macro, to check the fast repair box.
• Add ‘invert’ flag to pit chat macros so prepending – to front of command will unset it, i.e. -lf will uncheck the left front tire, also -clear will check all options.

Audio

• Turn off ducking of audio when Windows detects a phone call. Windows often confuses our voice chat as a call and kills the engine sounds.

Controls

• When we detect a joystick was added or removed, attempt to identify what controller was changed and only reinitialize that device. Previously we reinitialized all devices and this could lead to a momentary loss of steering control if your button box loss connection to the sim. You can revert to the old behavior where all devices are reinitialized every time a device is plugged in by setting app.ini [Force Feedback] initOnlyNewDevices=0.
• Added new keyboard backlight support for Logitech G910 keyboards. Now we dynamically highlight keys that have some function assigned to them, and color them by function. In addition the F keys act as a shift indicator/pit speed indicator if you are in your car.
• Removed code that would set the backlight on older Logitech keyboards and mice to try and replicate a shift indicator.
• Added support for LED lights in the new Logitech G29 wheel.
• The minimum threshold to detect motion when calibrating can be adjusted by the app.ini switch initialMoveThreshold. This can be used to get devices with very small ranges of travel to be detected by iRacing.

New Tire Model

• v6 tires now include a term in the lateral stiffness calculations that was missing in the NTM previously (including the v1-5 tires). All prior cars with v6 tires from last season have been revised to suit, and many more cars have been upgrade to v6 tires.

Black Boxes

• In the F1 black box, don’t show the same car ahead and behind you, if only one other car on track, or only one other car in your class.
• In the F3 black box, sort cars into position based on class, if no position is currently known for the car.
• Allow the virtual mirror field of view to be adjusted from the F9 black box.

Driver Aids

• The auto-blip shift aid now uses the new drivetrain physics model, instead of falling back to our ancient old drivetrain model. This significantly improves how smoothly the cars shift when using the auto-blip aid.
• Allow H-pattern gearboxes to be downshifted into neutral at speed when using sequential shifting controls.

Towing

• When someone is disconnected from the server via a connection failure, we now compute the tow from when we last saw them on track, instead of when the connection finally timed out.
