    Thanks for the answer! I guess we can hope that they will put more effort into it with the Index coming, good times ahead for VR in general i think :D

    I agree, great times for VR are ahead :) I just hope Valve guys won't break other headsets/games while improving Index support :) Or, maybe let's hope they will? More motivation to replace Steam VR with the open source alternative :)

    I am getting an Oculus Rift S today. It will be my first VR device. I only plan on playing Raceroom with it. Should I plan on doing this mod, or is Steam VR is a good enough state?

    I have an i5-8600K and a 1070TI with 32GB of memory.

    Anyone here using the Valve Index? If so, what kind of Graphic settings are you using in-game and in SteamVR? I've always found it hard getting a crystal clear image in RaceRoom ever since CV1. I've had the Vive Pro, Pimax 5k+, and now the Index. They all look OK but I've never gotten it crisp and sharp like I've gotten iRacing to look.

    Any help would be appreciated.

    Well the problem most likely that it a Iracing uses DX11 as R3E uses DX9 :(

    How could that be? I thought for VR to work it has to be DX11. I wasnt aware of that.

    DX9 isn't officially supported by VR, but it doesn't mean it can't be made to work with it. It just means that anything which is broken or incompatible will stay that way unless the developer finds a workaround, as they won't get any help from Oculus, Valve, or whoever.

    I find the game to be desperately cpu limited, even on a flatscreen.

    I lock the FPS at 120fps. But I can see the FPS drop down to ~115 when leaving the pits or when there are a few cars in front of me. The in-game overlay "dash.exe" also has an additional penalty of ~5fps on my PC.

    The cpu bottleneck is so bad, that my 1080TI is idling at 25% usage in these situations. How can VR handle 90fps at all times? In my Odyssey+ It cant.

    whats my CPU? an 9900K @ 5.1ghz.

    In VR whatever your CPU is you need to be reasonnable on your graphic options, just FYI car shadows e.g are penalizing FPS as much as AAx4 and 1.3SS... so often (except texture quality) off/low/lowest are your best friends for graphics options and maintaining 90fps in VR...
    Thomas and mine graphic options are described in earlier posts in this thread.
