(Not Resolved) Known Issue - Quest PCVR streaming micro lags and stutter esp. when moving head

Hi team,

I'm getting micro lags and stutter in Airlink on my Quest 3 (EU/UK), esp. when moving my head. In the Oculus debug overlay this causes brief spikes in transmit/decode, fps drops and visible stuttering. The issue is not present on my Quest Pro with otherwise identical settings - see below screenshots to illustrate.

Few more details:
- Issue is not present on Quest Pro with same settings on HMD, router and PC (using same res)
- Issue is worse at higher bitrates, esp. >200mbps, but still present <200mbps
- Issue is unrelated to PC/game latencies (CPU, GPU, Queue each <5ms)
- Stutters/lags are intermittent (every 10-20 seconds) when not moving but happen immediately and reproducibly when moving the head to either side or especially looking downwards (i.e. on any bigger headset movements)
- Wifi 6E router (TP Link AXE75 EU/UK)
- EDIT: exact same issue with Asus RT-AXE7800 (EU/UK) wifi 6e router
- Connection shows as 2,400mbps
- Airlink codec H264 (but same on other codecs)
- I've attempted factory resetting, installing latest drivers
- Updated to v62 and latest Quest Link desktop version (I can see the 120hz option for my Q3)
- EDIT: Ordered a separate Quest 3 for testing: presents the exact same issue

-EDIT: Same issue on 5ghz 802.11ax 160mhz BUT switching to 802.11ac (!) completely fixed the issue. I cant test this on 6ghz but looks like 802.11ax or something related to how q3 implements it is the culprit

As the issue is worse the higher the bitrate and not present on Q Pro with otherwise same settings, I suspect it's related to the below known Wifi issues - but opening a new thread as instructed.

Best,

Updates:
- Tried separate router: exact same issue with Asus RT-AXE7800 wifi 6e router
- Ordered a separate Quest 3: exact same issue on both routers

Oh, come on. Tried to play some skyrimVR via Virtual Desktop today, even by tethering the connection virtually to a cable. The decoder and the networker begin to stutter like hell when i use my touch controllers(especially when moving the thumbstick.), causing a very visible stream stuttering. My rig ain't having any problems, my gpu is at a literal 50% utilization and the cpu is merely being used. I'm on quest 2.

New Quest 3 unit came from warranty after almost 2 months of waiting. Pretty much same issues. Airlink not working the slightest, even more choppy and stuttery. Right now testing out Virtual Desktop maybe makes it usable.

WOW! This indeed fixes the problem with my AX50! I use a spare AX50 only for the quest 3 and Steam VR show latency about 3ms with 90hz.

As i have suggested on page 36 of this thread, i can now stream at 120 fps without issues with that setup using the steam app or virtual desktop. You just have to make sure that the dedicated access point is on a free channel.

Ive been playing now for the last few weeks with virtually no issues.

My PC: CPU - Intel 12700k GPU - Nvidia 4070 ti Super Ram 32GB ddr4 @3200MT Network - Asus ROG Rapture GT-BE98 - 2.5Gbps to pc Asus RT-AX88U as dedicated access point Meta Quest 3 128GB connected via dedicated access point

TP-link AX50 is known for having performance issues. The CPU can't handle Wifi6. That was also suggested by the TS. My reply was only adressed to acreed11 . Thanks anyway.

Same issue. It has been happening since I purchase quest3 in May.

It seems it was a network issue for you then. I tried multiple 5&6ghz routers, including the PrismXR pre V72 and they all did not solve the stutter. I wish I had kept my AXE75 so I could test it now with the V72 but the PrismXR seems perfectly fine.

Obviously it was a firmware issue with the Quest, which seems to be solved for now. What I do now is to ensure that firmware auto-updates are disabled. At least that will buy me a couple weeks before a then-forced update potentially breaks it again 😞

I should have specified: I am using VD over Wifi and it works perfectly well

Airlink however ist still broken, especially with ASW kicking in. Total stutter fest with unbearable ghosting, event at lowest bitrate and resolution. I believe tethered link was fine. I would try but I just rage-uninstalled the Link Software. What a mess 😠

I think its Meta because all of a sudden SteamLink is better for me than VD and this only came about recently for me, think meta can throttle the bandwidth some how?

For a very long time (more than three or four months) everything worked perfectly and at the end of last week the problem came back, although I did not change any settings in the system and did not perform updates. Whatever I do now, I still get a lot of dropped frames while playing through airlink. The interesting thing is that VD has become much better, although not perfect, but much better than airlink. Why did they break airlink again?

afaik, airlink isn't too "good". i'd suggest using virtual desktop for pcvr. other users/players notice a better wireless experience when using "vd" (virtual desktop). this has been the case in almost every vr game i've played using quest 2 or quest 3. (breachers, onward, etc.)

I have VD and until recently it worked much worse than airlink. Now that airlink is almost unusable again I use VD but it still doesn't work perfectly and there are many micro freezes during movements especially in steamvr games.

That's what I love about the Index and my PSVR2/PS5 - I just put it on and it works.

Well, actually my old CV1 still is like that too - so it's not like Meta can't make everything run perfectly, but maybe everything just got too complicated with the lastest Quest hmds for many.

I'd still love if Meta made a Rift CV2 - just put in the Quest 3 lenses, keep everything else the same. After nearly 7 years, my CV1 still works perfectly - that's a sign of awesome quality. 2c.

Is this multiplayer, perhaps if so, the opponents are on 5g, or less could make a game lag for a console, not sure about VR. Or alternatively maybe the game itself hsd too sprites, those are all the items you see on the screen as objects. Maybe the game needs to update better for your VR that you are having issues with. Could you try another game or even the time of day could be a factor. Are you having luck now ad wifi 7 is now out?
