The quest 2 headsets most definitely are using compression. They literally have to. There’s no way you can pump that much data through usb c, given the quest’s usb controller specs.
Does the quest 2 let you use steamvr supersampling in pc link mode?
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.

The current USB C standard can push 20Gbps. That’s a little faster than the displayport used for the Index (17Gbps).
The quest controller can’t do 20gb/s. It’s the Quest hardware limitation. It is compressed.
I think meta claimed around 5Gbps but real-world people saw around 2 - 2.5Gbps for quest 2.
Yea. That’s abysmal lol.

Agreed!
