The latest big update to iRacing has seen the addition of the Audi RS 3 LMS, three new NASCAR cars, the addition of Circuit de Barcelona and Fairbury Speedway and the V7 tyre model on a selection of vehicles. But any big release will tend to have minor issues, so the iRacing Season 4 Hotfix released earlier this week fixes everything discovered so far.
It’s a prompt response, considering the Season 4 iRacing release occurred on Thursday September 5th, 24 hours after the planned Wednesday publication. The issues largely cover the new content, including the cars and tracks. But there is also a new Logitech API for wheels, a change to the grip on the dirt sections of Rallycross tracks, and other tweaks.
