Does the GPU encoder tech on the RX 6700 XT compare to or surpass anything on NVIDIA Ampere?
With the Oculus Quest VR headsets, doing PCVR involves an encode/decode process, and uses the PC's GPU for encoding. The GPU encoder's power determine how high of an encode resolution gets sent to the headset, and thus determines overall clarity and compression. The general consensus is that AMD's encoders up until RDNA2 are notably worse compared to anything on NVIDIA (Pascal and up), and last I heard, even RDNA2's encoders were still behind Ampere. I'm wondering if anything has changed with the encoder on a 6700 XT?
I have Polaris (RX 580), and the encoder is bad enough on it that it makes 1st-gen PCVR headsets (Rift CV1, OG Vive) look more clear and show finer details than a Quest 2. So until AMD steps up their encoders, NVIDIA's the only ideal choice for VR with this headset.Last edited by Guest; 17 March 2021, 10:49 AM.

Just a friendly gesture to AMD users who are hell bent on using AMD GPUs, pony up the cash to buy 6800/6800XT 256bit or even Polaris 256bit instead. I have issues with AMD's design intentions with 6700XT and 6900XT SKUs.

Is there an apt install command for the upstream mesa "amf" package that HandBrake can see and use? I would love to be able to do GPU H.265 encoding in Handbrake using 5.11 xanmod kernel and mesa 21.0 ppa.
