Hoggorm Posted March 8 Posted March 8 Hello, Why am I capped at 90, 45 or 25 fps when trying to find a good setting for my VR setup? Is there one specific setting that does this? Why am I not at 76, 52, 41 etc frames?
ED Team BIGNEWY Posted March 8 ED Team Posted March 8 Hi, its usually motion smoothing or ASW ( Asynchronous Spacewarp for meta ) that will do this. Try with it disabled for your headset. 2 Forum rules - DCS Crashing?

It seem to have released the 90 fps issue, but I am still capped at 45 when trying to adjust for example Anti Aliasing DLAA - DLSS - from Performance to Quality. Quality looks better, I have the same framerate, 45, as Performance, but the frametime (that SteamVR shows in the headset) increases with Quality.

Is there one specific setting that does this? Why am I not at 76, 52, 41 etc frames? Because variable fps in VR are vomit inducing, so every headset tries to mantain native refresh rate (90 Hz in your case). If your pc can't keep up it goes into motion smoothing, where it renders half the refresh rate (45) and inserts a "guessed" frame between two real ones. You still see 90 fps but only half of those are real. That leads to artifacts when the fake frames are not predicted accurately. Never used a HTC Vive Focus Vision but I guess 25fps must be some kind of an emergency mode and surely it looks pretty bad, as most frames presented before your eyes are fake.

It looks nice, but the lag is quite unpleasant.
