Can Oculus on PC not play 60fps videos smoothly?
I'm building a Unity app that plays back 180 degree top/bottom stereoscopic 1920x3840 VR 60fpsvideo. I can get very smooth playback on Go and Quest with H.265 @ 31Mbs with Unity's default Video Player. I can't however get smooth playback on PC... I'm attempting with the following codecs: H264 @ 75Mbs, 50Mbs, 25Mbs, 12Mbs H265 @ 31Mbs VP9 @22Mbs, 12Mbs I've tried the following players: - Unity Video Player - Unversal Media Player With these players I seem unable to determine if any hardware acceleration is taking place. The PC I'm testing on has a RTX 2080 and an i5 8500 running Windows 10. I'm testing with an Oculus Rift S and Quest via link. All videos are somewhat choppy, even the lower quality ones. To get the playback to be smooth on the android devices, I had to set the devices refresh rate to 60 fps, the same as the videos FPS to eliminate any stuttering. It seems however you cannot change the fps on Rift, Rift S or Quest Link which run at 90, 80 and 72 fps respectively. Is there any way to sync up the refresh rate with the fps on PC or is there something else I'm supposed to be doing for smooth playback? How does other software achieve it?

Jerky MKV playback
Hi, I am currently using the the spatial worksation (facebook 360) encoder to encode the spatial audio to ouput facebook videos and Oculus videos. I made several tests and the encoded Facebook video plays very smooth on a samsung S7 Gear VR, but all my Oculus videos (for the Rift touch HMD) are converted into MKV video files and play very jerky. This was not the case a few months ago. Does anybody know how to solve this problem. The video file is about 1 Gb in size for a 6 minutes animation.
