CV1 with 1080ti, no issue in VR with any SIM, it works good even with ACC, but in R3E, I have super bad stuttering very often, only in VR, in pancake, no issue. I do not have high settings, which I use with all other SIM and only 11 opponents. Any help appreciated, as I am enjoying the FFB but not going to use my game with the stuttering.
I had also the feeling that the game after the big update was a little more demanding and I had lower fps with more cars. Particularly Nürburgring which is always a problem is now a little more demanding. You could try to run Afterburner in the background and check the CPU cores. On my PC some cores are at 90-96% means they are bottlenecks. It's time for Sector3 to move some calculations from CPU to GFX card.
It as been a few days, I would have expected some kind of official answer/comments from the devs, as this is the official support forum and I am asking in the community support question, am I in the wrong section to have help with an issue?
Breaking news, found a cure, stuttering completely gone. https://forum.sector3studios.com/index.php?threads/vr-performance-tweaks-tips.13068/
Can I ask what graphic settins do you run and do you achive a locked 90fps? I've got a 5600x/5700xt and I can barely maintain a steady 80fps with all lowest setings with a Rift S on Open Composite.
Can you say what you did to specifically fix the issue? Your link just goes to a long thread. I also have this issue.
