A minor update to the iRacing simulation is coming tomorrow. This marks the 4th update to season 1 of the 2021 season (which confusingly started in December 2020). Patch 3 was fairly minor as well, featuring mainly BOP and setup adjustments for cars.
Notable changes include:
- Further BOP updates – Mercedes-AMG GT3 and Ferrari 488 GTE
- NASCAR Cup cars – new parameters for low downforce packages at Daytona
- NASCAR Trucks – reduction in drafting strength
The patch will be going live tomorrow.
You can read all of the notes from the developers below or read the whole post on iRacing’s forums (requires an iRacing account.)
Changelog / Patch Notes (season 1, patch 4)
iRACING UI: (5.06.01)
3D Model Viewer
– Fixed an issue with the NASCAR Gander Outdoors Chevrolet Silverado not showing a custom spec map correctly.
SIMULATION:
Replay
– The Replay playback state will now be left alone when a user remains connected to the race server until the session finishes, and the server disconnects from the user.
– – A new variable, “leavePlaybackAloneAtSessionEnd” has been added to the [Replay] section of the “app.ini” file. Changing this value to 1 from the default (0) will cause the playback state to also be left alone between Session transitions (like going from Qualify to Race).
