As posted elsewhere,
I have been going through the motions with very little success.
What I did found:
When benchmarking VR in Ultra Low graphic setting I got around 30 FPS
When benchmarking VR in High setting I got around 27 FPS
While benchmarking wearing my Quest 2:
If I held my head still or resting against the seat, the graphics where ok (for 30FPS)
However, the moment any head movement was involved, it would take about 1.5 frames or 120ms to catch up with the movement, causing the jitter.
This tells me it is a refresh issue and the Quest2 or HMD is not getting the information quick enough from the game.
This is very much game related as no other sim in my collection is doing this.
Hopefully this will help those @EA or @Codemaster fixing this issue..
We can only hope.
