The only interest I have in the Quest 3, is if it can provide a better experience than the Quest 2 for PCVR.
The Quest 3 has Wi-Fi 6e capability, but will it improve latency and video compression of the Quest 2?
Right now the Quest 2 averages 47 to 57ms of latency, that and the video compression is unacceptable for people who use PCVR headsets with zero compression and 11ms of latency.
I'm going to order one from Amazon, so I can return it if it can't improve on the Quest 2, but any help before hand would be appreciated 🙂
When does Meta update Oculus client for Quest3? Godin implements more & more for VD. I don't use VD. But it's true that there isn't merit to use Link except "960Mbps on wired" & "free" now.
I bought Virtual Desktop a while back but only used it a couple times, I really need to get back and give it a thorough testing, otherwise I'm not getting my money's worth.
A lot of people say it's better than Air Link, and I think the only reason I haven't used it much is because my Air Link is very good. As mentioned already, maybe it's the Quest Pro's WiFi hardware that has better signal reception (I don't have a 6e router) or the processor boost improves decompression.
I used wired Link with my Quest 2 all the time for PCVR and still use it with the Pro when I'm having a static seated PCVR experience... or any PC session that's going to go past the headset battery life. If you have to plug into a battery pack when playing PCVR, you may as well use wired Link. I just don't like the cable when it's something like Fallout and you're moving your head and arms a lot. OK for MSFS and racing sims as long as I don't keep running my chair over the cable.

All right, have Elite Dangerous in VR a try, with cranked settings - rendering at 4128x2208, HEVC encoding at 4064 width, and 200Mbps over airlink (AX wifi, 160MHz, 3 meters from me on head level).
Image is stunning, latency not though 😄 I had between 60 and 80few ms.
I'm on 5GHz, from the network standpoint 6GHz does not give you a lot more - 5GHz 4x4 MIMO setup is able to push ~2Gbits trough air between two linux hosts. The usual bonus for 6GHz are less crowded channels, but that's not the issue for me, rarely anything here up in the air. I kinda feel like introducing 6GHz to the bunch was mostly for that reason, in populated areas wifi nowadays is a mess, often with people having unregulated 5Ghz radio links pushing few W.
And the best result of my yesterday tinkering is... ...burned in ODT performance overlay on my Quest 3 screen! Nowadays LCDs should not burn in, right? o_0
According to wiki LCD burn-in is a thing but it's to do with pixels not returning to their relaxed state after prolonged static 'on' state, but is temporary compared to OLED.

I saw that effect on mine too against a grey background, same cause, the overlay. It disappeared after something appeared to 'wipe' the display while loading a game. I've seen this with some LCD types, notably on my gameboy advance with an aftermarket LCD panel upgrade. Very specific image conditions seem to cause it. It's not permanent, but it's a little odd.
Anyhow, I want to use 6GHz because the crowding of 5GHz in my apartment block is so bad that wireless VR is unusable. I've been struggling along by grabbing DFS channels but there's radar contention so I'm never able to retain them for long.
My testing shows that with Airlink, 5GHz is okay, but 6GHz is not stable and the stream desyncs every several seconds. However, using Virtual Desktop 6GHz functions perfectly. So something is up with Airlink.
I wonder if it's possible that AirLink reconfigures "itself" on WiFi 6 - like using different codecs on cable (looks like Airlink uses h265 and cable switches to h264 in my case). Have you checked the performance overlay, the one with encode details? Maybe it switches to some insane bitrate on 6GHz
I'll settle in to do some more testing soon, and I'll report back as I do.
All I've done so far is test various dynamic and static bitrate settings in the Airlink home settings only, from 75 to 175, with everything set to default in ODT. I would expect it to respect those limits. It's definitely worse when I increase the bitrate limit, but on dynamic it should be smart enough to adapt appropriately if the throughput isn't good. But of course, it is; the WLAN link speed always maintains 1800 or higher, and of course Virtual Desktop runs with high bitrate and quality settings without a hitch. This leads me to believe there's just something that needs to be addressed in the Airlink deployment for Q3.
