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

same issue now after updating to V62 on VD

Unortunately I have the same issue. I have nearly an identical setup, brand new Wi-Fi 6 router, a recently upgraded high-powered PC and I'm getting stuttering when I'm moving my headset within airlink or virtual desktop.

I have tried multiple different settings in my router such as channels, frequency and Wi-Fi type, but no improvements.

It seems META is putting their head in the sand with this one and ignoring the issue.

I'm experiencing the same issue: Quest 3 on v62 (120hz) connected via 6e to an AXE75 (US), performance overlay shows easily reproducible xfer spikes upon head movement or large scene change. Bitrate reduction only helps slightly. Issue manifests as visible stuttering during gameplay.  All involved devices fully updated.  CPU/GPU load and other latencies are low. 

With both my QPro and Q3 I get the best results with Air Link using 200mbps Dynamic bitrate (set on Rift home dashboard far left icon).  All ODT settings default/zeros except distortion = Low.  This uses hevc (h265) and I've found this looks best and has the lowest latency.  Also less stutters, esp. with SteamVR apps.  Also, I prefer 80Hz refresh rate since I can't tell the difference between it and 90Hz, plus it gives my games a little more headroom.  If I drop this down to 72Hz I can start to see a little blurring/ghosting with fast racing sims.

Nvidia control panel global 3d settings all defaults except Power = prefer max performance and change the Quality default below that to High Performance.

I've found this gives me as good-as what I can get using Virtual Desktop, maybe a little smoother with Air Link, for me anyway.

For flight and racing sims I often use my official Link cable with ODT encoding bitrate set to 500-650mbps,  This automatically uses h264 btw.  I get about 7-10ms less latency and a little better distance clarity compared to Air Link.  Anything higher than 450mbps results in no significant artifacts.  Anything much higher than 700mbps and I start to get the odd audio stutter and higher latency.

Anyway, this all works great with both my QPro and Q3.  Probably helps that my PC specs are pretty high = i913900k/rtx4090/32Gb 6400ram.  Pretty standard 1gig router, ethernet wired to my PC, with dedicated 5Ghz wifi (ch36/80mhz) 2-3m away from my play areas.  Also, only 5Ghz user with the rest kicked to 2.4 with band steering disabled.

I have the same issue with encoder frame drops / lag spikes on Airlink.

My specs:

Quest3

i9-9900K

32gb RAM

3080 graphics card

Wifi signal strength is consistent at 1200mbps.

I have a dedicated 5Ghz wifi on 80mhz channel width. The router is ASUS RT-AX53U. No other device use the same network. I've checked for channel interference but that's not the issue either since it is the only wifi network on that channel. Router is in the same room.

I don't have this issue on wired link.

I didn't have this issue until v62 rolled out.

After trying all sorts of things over the last couple of days I might have found an acceptable solution. I disabled "802.11ax / WiFi 6 mode" on my router. Transmission speed is lowered from 1200mbps to 866mbps but almost all the stuttering is gone. Some stuttering here and there but it is acceptable. In ODT I'm using a fixed encode bitrate of 350 but found that 300 is slightly better. Going up to 500 made the stutter more frequent.

Quick update: purchased and tried with Asus RT-AXE7800 (wifi 6e router) - exact same issue unfortunately.

fyi I have few people across my Discord and Reddit channels also very much still getting this issue.

FunkyTanukiTheAntiSocializer any advice or feedback here? Appreciate any help! 🙂

I think that I have the same problem.

I am having a lot of frequent stuttering both in Air Link and Steam Link connected wirelessly to my PC on my Meta Quest 3. This happens on every game, and even on the Steam VR dashboard. It also happens no matter what bitrate I use, although perhaps it happens a bit more frequently at higher bitrates.

My PC has a Ryzen 5950X CPU, a RTX 3080 GPU and 32 GB of RAM. I have it plugged to the 2.5G port (I also tried the 1G port) of my dedicated router, a Asus RT-AX86U Pro. This router is then plugged to my internet router using the WLAN port.

I have tried Channel bandwidth of both 80 Mhz and 160 Mhz, and also setting the Wireless Mode to AX only (by default it's Auto).

When I am in game, if I look at Steam's performance overlay it doesn't seem to be dropping frames, and seems to be rendering more than adequate framerate all the time, even when I get stuttering. In the Meta Quest Wifi settings, I can see that the bitrate is 1200 Mbps when Channel bandwidth is set to 80 MHz, and 2400Mbps when it's set to 160 MHz. It also says that the signal is excellent (my router is just a 2-3 meters away from the center of my playspace).

Although I experience a little bit of stuttering from time to time when I play standalone on the Quest 3, it's nothing compared to the constant stuttering of Air Link and Steam Link.

I checked for WiFi congestion in my area with WiFi Analyzer and there isn't many people using 5GHz around me, the channel that I am using is completely free. My signal quality is excellent 

Do you have any suggestions?

Thanks! 🙂

I changed a setting in my router configuration that seems to have reduced a little the stuttering, it still happens but less frequently.

The setting I changed is 802.11ax / WiFi 6 mode set to Disable.

I still have some stuttering though, I recored my Steam Link graph that shows some big latency spikes some times:

My quest is apparently in v60 though, but it doesn't detect any updates?

Jens (and others), have you had a chance yet to check whether v62 fixes this issue for you at all? v62 appears to be available for many in PTC as of today.
