Continuing the discussion from 5K Plus with AMD 5700 XT
I choose to create a new topic in order to avoid pollution of the previous one.
So as a summary, i own a Pimax Artisan with 5700xt Nitro+ GPU and R5 3600 CPU. And i’m totally new regarding VR, this is my first headset and i’m already convinced, VR is so great, especially for my usage, which is simracing moslty.
First settings were 90Hz Pitool 2.0, smart smoothing OFF and SteamVR SS 50% (total resolution is 3172*2980), with these FPSvr is reporting most of the time 90fps (GPU-frametime < 11ms) with some drops to 12ms (or 13ms in really heavy traffic with 24 AI). But i was maybe capped by the maxRecommendedResolution Steam setting to 4096.
So i did the modification of the file, setting maxRecommendedResolution to 16384. And motion smoothing to false.
And i feel like nothing changed, so reports FPSvr, it’s like before in a matter of FPS. But if i set much more resolution with SteamVR SS, then FPS go down heavily.
I realized also that if i turn smart smoothing ON, it works, i means sometimes FPSvr reporting like 45/50fps but the GPU-frametime is still under 11ms. So it’s smooth as before, without FPS drops i would say. Still running 3172*2980 but with Pitool 1.0 and SteamVR SS 200%.
But, when smart smoothing is ON, once a turn my head from side to side, i see cars in double, if i don’t move my head it’s OK, it’s smooth. So in the end the feeling with smart smoothing is worse…
So don’t really know what to do. I mean i would like to use smart smoothing from Pitool and set resolution higher in order to rely on it and have the best visual/performance balance, but this issue makes it difficult.
