No problem Stairlift Don, will do! Maybe star it out like a sweary if it's grating?

I played Skyrim VR last night and I didnt see any loss of detail, banding or anything like that. All I saw was close up textures, characters and the cart at the beginning was fine, the buildings further away were a little blurred. Not something you would say "oh thats crap I cant play that". I`m going to try Skyrim VR again with a USB cable just to see if there is a difference.
Ideally I need to play HL Alyx as that was last played on Quest 1 with RTX 2080 and that was glorious.
I don't know if he is a Nvidia shill or not.
But, in regards to VR on the Quest 2, He is 100% correct. It's not an opinion, it's fact. Nvidia's GPUs are better than AMD's.
To the OP @barbel , if you want the best experience on the Quest 2 in PCVR buy the most powerful Nvidia 3xxx GPU that you can afford.
IF you want to purchase the 6900XT/6800XT, go ahead. Those cards are fine for VR. Just as long as you are aware that Nvidia's GPUs are better for the Quest 2. They are better in general for VR, but AMD's RDNA 2 GPUS have almost closed that gap.
Ok so I've had a proper play now. This is regarding Skyrim VR only.
Virtual Desktop works the best with regards to the actual image not flickering or any compression artifacts etc but compared to using a USB cable its like playing with a 720p image.
Airlink is just terrible its worse than Virtual Desktop. In Oculus home the floor textures constantly shift same for the brown in the walls. In Skyrim its slightly more detailed than VD but whole screen flickers every second or so which is quite annoying and I guess there is what you would call latency issues etc.
Optical Link USB cable is the best image quality (using z10m settings in Oculus Debug Tool) but I am still getting that whole screen flicker every second or so which can be quite annoying. To describe it better its like watching a picture that goes out of focus every other second then pops back to proper detail.
I guess really it needs some on screen display of the quality settings and latency etc but I`m not going into all that youtube crap.
Anyway this should answer your original question. As Cilla would say (actually it wasnt Cilla it was the voice over man) with regards to what you buy "the decision is yours".
Thank you for trying seems I'll have to stick to nvida cards to get the best display which is a shame as I fancied a 6900xt
Hope it works out ok for you.

That is weird. When I first got my quest 2 when it was first released I got a official cable. I hated having the damn thing always underfoot!
Virtual desktop ran WAY BETTER for me on a 5g internet planthan wired.
No issues at all with vr games on a 6600xt.Such as Starwars squadrons, Asgards wrath, Doom Vfr, shadow of tomb raider,.Skyrim is a crap port for Vr whatever card you have.Which is why I'm going to mod the hell out of it in 4k textures.
I've bought a 6900xt now for $1200 New Zealand dollars,about $600 less than what a 3080 goes for new here. Im really happy.A 3080ti? Would be $2000.

The information about the encoding limits of AMD GPU's is really interesting.
Re. some data on NVidia vs. AMD performance, AMD have sadly been a bit behind in VR titles for a bit now. Things are slowly improving with better UE4/5 integrations, but still lagging NV. I've been pretty meh on my 290x, Vega 64 for VR.

Does anyone know if the Rift S uses h.264?

I've had a Quest 2 since launch with a RX 580, 6600 XT, and RTX 3060. It was absolutely terrible on the 580 (muddy compression, higher latency) and was notably worse than a CV1.
With the 3060, I was able to do HEVC with Air Link at 200Mbps with good quality, low latency, and AVC with wired Link was also decent. Oculus benchmarks and sets the highest 3664 encode resolution with both. No driver issues either; I installed the latest driver and was good to go. 90Hz and 120Hz worked fine.
With the 6600 XT, HEVC with Air Link is only possible with certain driver versions (notably 21.10.2), and even then, bit rates either aren't set properly, or AMD just isn't that good at handling that even (200Mbps HEVC looked about as good as 50Mbps AVC). The encoder in any case can't handle 120 FPS seemingly at any encode resolution (encoder FPS is 100-116).
VR with AMD is largely mixed or broken for the last 5 driver releases now (May preview, all "4" 22.5.2 drivers, and 22.6.1). AVC is broken (Oculus logs spam something about it), Oculus Dash gets visibly broken (ghosting). And I remember with Polaris (580) where they outright broke VR for 4-6 drivers back starting with 20.10.2, and even today the recommended driver for Polaris is still 20.10.1 back from Oct 2020. And even with all the reports about VR and encoding being busted, none of this is mentioned in driver release notes. None of the last 5 current driver releases even hint at VR being broken.
I've debugged this since the Q2's launch and can say with confidence AMD is not an ideal choice for VR with a Quest 2, and likely all headsets with an encode/decode process (Vive Focus, and Varjo Aero even though they outright claim they don't support AMD GPUs). You have to deal with driver and encoder issues. You can make it work and it's tolerable, but it's worse than anything you can pull off with NVIDIA. Driver-issues aside, RDNA2's encoder capabilities aren't as-good as Ampere. Even though a 6600 XT performs better than a RTX 3060, the encoder is notably worse, and the GPU encoder is the main factor as to how VR will feel and look with encode/decode headsets.
For direct-display headsets (CV1, S, Index, Reverb), AMD is fine.

It's direct-display (no encode/decode)

My take away has always been that the 6900XT should imho have been pitched against the 3080 from the start.
There are some VR users in the DCS and Elite communities that claim performance advantage with the 6900XT I don't know reliable that is though, you do seem to benefit from larger VRAM sizes in flight sims as a general rule.

For VR go Nvidia no matter what the headset. AMD are closing the gap, but, it's still a better VR experience with Nvidia.
EDIT: That's if you are comparing cards with roughly the same performance in pancake games.
Rift S doesn't use any codecs, It's connected directly to the video card's display port.
