Add FPS setting to XR Plugin #267

Open dipaw opened 3 years ago

dipaw commented 3 years ago

Hi. Is it possible to limit the fps through a plugin? Unfortunately, many devices do not have active cooling and constant 60 frames is hard to maintain, limiting to 45 and 30 would help a lot.

Thanks for reaching out to us. Have you tried using Unity's frame rate setting?

JIC, bear in mind that the Cardboard XR Plugin does not play well with the Optimized Frame Pacing option on Android devices (see https://github.com/googlevr/cardboard/issues/245 for more details).

Unfortunately it doesn't work. The only way to change the frame rate in the XR Plugin that I have seen is the API in the Oculus sdk. We need an analogue of this command in Cardboard. Unity.XR.Oculus.Performance.TrySetDisplayRefreshRate(120);

Hi. Perhaps there is a way to enable VSYNC ? Unity VSYNC doesn't work too.
