2021 iRacing Season 3 Patch 4 released 29 July

Justin Melillo

The fourth patch for the third season on the 2021 calendar year for iRacing is now available. This patch is, well, fairly managerial in the sense that there’s some random fixes and updates that likely were needed, but there’s not much to pick out that stands out for members to be excited for.

There haven’t been many patches in this particular season, comparatively to the last few at least. We know the scan van is back on the road, however, and there may have been a tease of new content during the NASCARCADE documentary on FOX Sports 1 on Tuesday night, so there could be new content awaiting us for the Season 4 build.

An interesting note on the Porsche 911 GT3 Cup (991) is in there. It was running the New Damage Model, but this update has reverted it back to the old one to “take advantage of some updates and improvements.” Likely, that car and more will get NDM in future updates.

Laguna Seca has been on the service for as long as I can remember, so it’s nice to see that it is getting its name updated properly. Mostly, this patch has UI updates as the desktop program continues to evolve. Many of the features that continue to develop are on the UI program now… That’s still not going to stop me from using the member site for everything else, iRacing!

We’ve got the full patch notes below, as well as a screenshot from the updater from an account that owns 100 percent of the content. Sometimes, there are updates to content not listed in the patch notes. It seems that Bristol Motor Speedway, Five Flags Speedway and The Bullring are getting some update, but it’s not specified exactly what.
