You’ll need to spend some time downloading the latest updates before your sim racing weekend starts with iRacing 2021 Season 2 Patch 1 released this week, and a further Patch 1 hotfix scheduled to arrive at 13:00 UTC.
The reason for the quick hotfix is the new damage model causing issues with specific cars. In this case, it’s the ARCA Menards Chevrolet Impala, the 1987 NASCAR Chevrolet Monete Carlo and Ford Thunderbird, and the Street Stock. In these cases, the damage model has been disabled for the time being until the solution can be made available.
Aside from that, there are some significant changes to the tyre wear race for the GTE cars, so you’ll need to change tyres more often. And there’s a balance of power adjustment for the new McLaren 570s GT4 and the still relatively recent BMW M4 GT4 to enable them to race the Porsche 718 Cayman GT4 Clubsport MR more effectively. All three have arrived in the last 13 months, so it’s not surprising a little bit of balancing is required.
Along with graphics changes to various circuits, probably the other major highlight is the turf at the final corner of Laguna Seca should no longer trigger an incident point if you run onto it.
iRacing 2021 Season 2 Patch 1 Changenotes:
iRACING UI:
Practice
– Fixed an issue where the drop-down menu for selecting a Setup for an Open Setup Practice was not rendering properly.
3D Model Viewer
– Fixed an issue where if a car already had a custom spec .MIP file actively loaded onto it, it would not update when a new custom spec .MIP file or custom spec .TGA file was copied into the folder.
– – For a .TGA file to replace the .MIP, it must have a “last modified” time that is newer than the .MIP, or the .MIP needs to be removed first.
