Updater
– Improve how the iRacingUpdater.exe identifies if a computer requires a DirectX file update to deal with certain combinations of 32-bit vs 64-bit shenanigans.
Controllers
– Improved calibration routines to work around detection issues with certain devices.
Graphics
– The app.ini [Drive Screen] UIOffsetBottomPct=0 setting will now show up in the .ini file by itself, instead of having to cut and paste it in by hand.
– Add options to renderer.ini to disable compression for helmets, suits, and cars independently.
New Tire Model
– NTM v5 has more rolling drag in this season’s update than in last season, but this also means the rolling tire noise is now a lot louder than it should be. We have retuned the rolling tire noise levels for the NTMv5 cars back to where we want it.
Tech Inspection
– Weather conditions no longer affect tech inspection. Issues were arising where a hotter or colder day could cause a setup to pass or fail tech due to tire pressure ride height variances.
Chevrolet Impala Class B
– Updated setups for Bristol, Phoenix, Texas.
Dallara IndyCar
– Updated setups for Iowa, Kentucky, NHMS, Phoenix, Pocono.
Ford Mustang Class B
– Updated setups for Bristol, Phoenix, Texas.
– We no longer unintentionally show a development information tab in the garage.
Ford Falcon FG01 V8
– Updated the baseline setup.
– Restored the correct aerodynamic drag. We had been doing some testing of the car for NTM v5 tires which have higher rolling drag, so cars need their aerodynamic drag reduced to retain correct top speeds, but when switching back to v4 tires for release the lower drag was not restored to where it should be.
Skip Barber Formula 2000
– Remove the front ride height tech inspection limit that was causing tech inspection failures in cooler weather.
New Hampshire Motor Speedway
– Updated to include a new Legends oval configuration.
Mount Panorama Circuit
– Added some more greenery to the scenery.
