Did some more flying last night, definite performance improvement in VR. Outside of built up areas the CPU frametime is below 10ms which I've never seen before in MSFS.
Dropping my render resolution on the G2 down to 75% resulted in 48-50fps for the most part, making it possible to largely lock to 45fps rather than 30fps... even in the TBM with the glass displays (with refresh set to high) it was maintaining over 45fps. Before when I tried to hit 45 I had to come significantly lower (I believe around 50-60%) and still couldn't do it as the CPU would get in the way of maintaining the 45fps minimum.
So I now have the option of VR at 30fps at 100% with a little headroom (maintains around 35fps typically with my settings), or 45fps at 75%. I got none of the sim pausing hitches and frametime spikes that plagued me on earlier versions and much better smoothness even at 30fps with significantly less stuttering and blurring on close by objects when looking out the side.
Worth mentioning this is using the Steam OXR runtime which traditionally performs worse onthe G2 than the windows one, so potentially there's even more room there if using the native runtime. Alas I can't apply motion compensation without using steam's version so not an option for me.
Fingers crossed the hotfix sorts out most of the issues others are having.
Wondering why you say you can't use motion compensation/ reprojection without using Steam's version? I thought you had the Gamepass/ Windows version, Guess simple answer is you only have the Steam version of the game now.
Also, when you run without any motion compensation, do you use a 30fps/ 45fps lock cap (like Rivatuner or similar?)
I'm really disappointed this sim update 5 has done bugger all for my VR performance. Why can my system, an 11700, 3090, 32GB fast RAM, NVME, Reverb G2 not maintain 30fps with motion reprojection on in VR? This is with OpenXR render scale at 100%, in game render at 70%, high and medium settings.
It's no different to when I had my 5930k x99 system paired with my 3090. I thought a new gen intel CPU, RAM and motherboard would really help Flight Sim 2020 but it made no real difference, and now this fabled update 5 has made zero difference either for VR.
If I run with motion repro off, I can maintain 30fps locked (via Rivatuner) in VR easy with the above settings, but there is still random horrible judder just like before so it gets annoying.
