Quest has a per eye screen resolution of 1600x1440. When connected to PC via LINK at what resolution should I run the video game? Or does it not matter because of the way the Oculus application encodes the video stream.
It probably does not matter (much) due to the streaming - but whenever possible you can try to increase res and see if it makes a difference. Seems that some Quest users noticed better image quality when SteamVR res was increased, but the performance impact may be significant - depending on your gpu.
