This might be worth exploring if you have fps issues in VR in racing games ( I mean, any VR games really, but it might be amazing in iRacing and ACC if it works).
I watch him a fair bit, he’s fairly lo-fi but I mostly like his takes on various technologies and games, and he seems to be getting good results here with the caveat that some games don’t seem to work. Those that do, however, seem to be significantly sharper and smoother.
Essentially it’s a mod you can just drop in to replace the openvr dll file in any given game and then use a text file to tweak the settings. Apparently you used to have to force steam vr with oculus headsets, but he’s literally just now released a version that should work directly in the oculus runtime.
I have no idea if it works in our sims yet, but it might be worth a shot. Just make sure to rename the original file in case you need to revert. Don’t overwrite.
