@mac2244 @RomanDesign There is definitely something wrong in the implementation nonetheless.
Yesterday I tried the B350 over Hawaii and I could raise to TAA70+SS65, TLOD100, Reproj. and it was silky smooth. Right after I’ve tried the Citation Longitude at KMCO and it was stutter fest. None of the mouse trick nor exiting VR, closing WMR portal, then re-entering solved this. Only after maybe the 3rd attempt, all of a sudden no longer swapping back and forth blue/red in the OXR overlay, and silky smooth like with the B350 over Orlando with TLOD100 still but TAA60+SS65.
I’m certain this bug is also affecting VR in non-reproj and might account for the so varied reports we read in the forum because it makes no other sense there is so many running fine, and so many others aren’t.
This doesn’t preclude WMR Reproj is causing some artifact and it is a technology which is working better for aircraft without a front propeller for this reason, but when it is working, I must admit I find it is giving a weird impression of false fluidity to me but it is eliminating juddering, which is enticing.
This still leaves open the questions: is it NVidia driver bug induced? is it WMR “preview” v105 known bug internally? is it FS2020 rushed VR release because of a deadline (the 22nd) and this is a known bug they already have a correction for?
At least, this experiment shows me a 9700K+2070S is capable enough delivering FS2020 VR experience to its fullest once this specific bug is corrected. Once it is solved, I’m also certain I’ll be able to raise a number of other settings without any incidence to the fps. In the meantime, if the simulator is stuttering like this, I also know I need to exit/enter VR a few times until it is curing itself, and I know I have to lower some settings to give the CPU some room to help. This is good news overall!
PS: since different NVidia CPL settings are giving better results with reprojection, this leads me wondering what the same NVidia CPL settings will give if using SteamVR OpenXR now.
