ALVR unplayable on POP!os 24
system:
CPU: ryzen 5 7600x
GPU: RTX 4070 SUPER
visor: quest 3
months ago i tried ALVR and was running smoothly, some time has passed (didn't used it for university reason) and today it doesn't work anymore.
i cannot select H264: when connecting with the visor there's an error saying: "provided device doesn't support required NVENC feature"
when selecting HEVC i can connect, but it's literally unplayable:
i don't even know what happens with the throughput, spikes of literals GB/s
the biggest delay is the game render (in this case only steamVR), other delays are quite stable
the framerate seems playable looking through the visor, but when moving the head is costantly jumping and the controllers aren't there.
changing resolution, hz, TCP/UDP changes nothing, the reaction is still the same.
here is some log:

and it continues with those desync messages until i kill manually steamVR (also for not throwing up in the visor for the costant jumping of the view)
another thing is that the head movement is smooth, but it jumps every 15 seconds, especially if I move my head.
with big movements i see the void (black borders outside the view)
