2023 iRacing Season 1 Patch 2 includes new BoP adjustments for GT3s

With the iRacing Daytona 24 just around the corner, the latest patch for iRacing in 2023 Season 1 is set to update the Balance of Performance (BoP) for the GT3 cars that will be competing in that event. The latest patch also brings with it a host of other changes, fixes, and updates as well.

Starting off with the big one, the GT3 cars from Audi, BMW, Ferrari, Lamborghini, McLaren, Mercedes and Porsche have all gotten a BoP adjustment for Season 1 on Monday. While the McLaren isn’t a part of the Daytona 24 lineup, others may seek to utilize it in hosted competitions.

The BoP adjustments will change variables such as vehicle mass, engine torque and fuel efficiency. All GT3 cars received further updates with the New Damage Model which was implemented in this season. The Lamborghini had a NDM issue specific to its car as well as a graphical glitch fixed.

One of the other cars in the Daytona 24 field, the Dallara P217 LMP2, also has gotten some NDM love, while the Porsche Cup 992 car has gotten a “small set of vehicle properties” that have been updated as well. All those BoP, NDM and other updates are listed below.

There were some updates for the iRacing UI, iRacing AI, as well as some adjustments to Race Control procedure. The ongoing fallout of the iRacing – IndyCar split means that all the former IndyCar products have also had branding updates for their Dallara cars and Mazda cars that had the branding previously.

The new version of VIRginia International Raceway also has had some tree updates. Hopefully that means my personal PC will not melt again the next time I load it up. As for the rest of the patch, it’s fairly light. Shout out to the Centripetal Circuit update. The rest of the notes can be found below.

NOTE: For a short while, when iRacing was down for maintenance, some users reported being able to practice the Porsche 911 GT3 Cup (992) car with the option to select dry or wet tires. This was likely unintended as the feature was removed in a quick hotfix for those who had already done the update.

While this likely means rain is on the horizon (we’ve also seen windshield wipers get activated on some road cars in previous updates), there is still no new news on rain at this time.
