I know this setting and already use it, but if the user is not selecting 120HZ mode in his device settings -> it will still run at 72HZ, at least from Metrics tool info and unity analysis.
So it doesn't help with the problem. I was wondering if we can force the users device display refresh rate to be 90 HZ. On the Quest 2 the default is 90HZ and on the Neo 3 the default still seems to be 72HZ.
The game is very well optimzed and running perfectly smooth with 90hz on the Quest 2. It also runs fine with multithreaded rendering on other VR standalone platforms.
The problem seems to be that multithreading is not working properly. I have to deactivate it to not have jitter -> from analysis in unity this seems to be a problem with multithreaded rendering taking too long and delaying the frame render.
