All unreal projects are being limited to 45 fps and 22ms on my 970 on all projects, I even downloaded the steamvr template and the same problem.
Has anybody had this problem? My video card is at 60C so it’s not overheating
All projects in my DK2 were running fine at 75 fps
I think this is one of the settings in the vive prefs. Reprojection is what I want to say but I don’t think it’s that - whatever it is its in the performance tab.
To clarify, I think it renders every other frame (45fps) and repositions/reuses each frame twice over the 90fps.
This is indeed reprojection. It will kick in if it thinks you can not hit 90FPS and will halve your framerate and generate every second one from previous render data, so the fix would be to optiomize your scene, look at the documentation and forums on how to do so as it is a very common subject. Sometimes reprojection will starts too aggressively so you could actually hit 90FPS if you disable the feature, but it is best to make sure your game will run at 90 even when the feature is enabled because you will not have control over what the end users will do.
