Huh super interesting, this just made me look it up. USB does in fact use compression, but how much will depend on the bitrate set in the Oculus Link app.
I don’t VR that much, but I remember using wired USB with Oculus Link without tinkering, and I couldn’t tell that it was compressed, ever. Like crystal clear output, no signs of artifacting or anything.
Which is wild to me, since DisplayPort over USB-C is a thing. I just looked and it’s capable of 4k@60Hz with 24bit color and no compression. So I guess it’s just a limitation of the Quest 2’s XR2 chip.
After a quick search it looks like Quest 2 over USB can use Steam VR’s super sampling. Since it’s baked into SteamVR, it seems like basically all connection methods can use it.
Thanks for the heads up, I would have never guessed it uses compression!
I believe that the compression is hard to see in certain scenarios. But i just want that sweet sweet uncompressed raw signal source lol. I wanna use my PC to the fullest extent for VR graphics.
Luckily I think the rumors are that index 2 will be real PCVR but also wireless. So hopefully that means we can have actual displayport or hdmi uncompressed.

Agreed!
