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

Hi acreed11 

I personally have experienced this issue at one point. What I did to fix it was turned off QOS settings, and disabled all port forwarding and triggering I had setup for other apps. I am running the Netgear Nighthawk XR1000 and it is giving me lag free play now. For some reason router QOS seems to occasionally interrupt the stream. Finally I also recommend using the 5Ghz channel and be in the same room, in an uncongested frequency. Sometimes users will get WIFI interruptions due to two channels either too close to the same radio channel frequency, or exactly on the same radio channel frequency conflicting. 

The 5GHz radio only works well within line of sight, because the frequency is greatly compressed compared to the 2.4Ghz radio. It leads to greater speed, but less coverage and requires line of sight to work well for VR.

Finally, also make sure that no one else is using the 5GHz radio but you. It is actually best to use a dedicated router for VR, however in my experience it is unnecessary. 

TheAntiSocializer I think I've found a solution or at least something to start looking at for the root cause of this problem.

Enabling a Dynamic Bitrate Offset and setting it to 30 in ODT and the issue is completely gone.  My working theory is that there's something happening in Airlink when the received data from the computer fluctuates and the Quest is just bottoming out the decode bitrate instead of slightly adjusting.

My issue is just as the tittle says. I have micro stutters all the time. Even when I'm just in Oculus home or SteamVR home. It's really annoying and distracting. Could this also be related to the fact that i can't seem to disable asynchronous space warping? I am using the kiwi design link cable, and using a Meta branded Quest 2. My specs: RTX 3060 ti, Intel core i7 12700k, 32G Ram. I am on windows 11 btw. I saw that someone else had a post with the same issue as me, but there was no answer on that post so i made my own. other post

EDIT: My post has been forefully merged into this one, and is not the same issue as everyone else is having here. I am on a LINK CABLE, not airlink.

Same issue as everyone 😞

Intel i9-10900K, 64GB DDR4 ECC RAM, RTX 3080, Windows 11 22H2.

I've just bought Quest 3 and had a great experience with a 5GHz router in the other room.
I wanted the best experience possible, so I upgraded to 2.5Gbps network card, 2.5Gbps switch and 2.5Gbps Wifi 6E Ubiquiti Unifi U6-Enterprise access point, which I've mounted directly over my play area.

I had some issues trying to get it on Wifi 6, but everything connected successfully in the end.
But since then the experience has been terrible - bad quality, horrible stutter when moving and it made me sick, the games are unplayable, also random disconnects from Airlink.

I'll try to disable the 6GHz on the Ubiquiti and post back if it helps, but it's a MAJOR bummer. 

Question to everyone - is it really a software issue? Did Wifi 6E work flawlessly before?

EDIT1 - switched to 5GHz on the Ubiquiti and the issue is gone, I just feel like the quality was actually a bit better on the router next door, I'll do some more testing.

I think I'm closer to the truth than ever before. Based on all my observations, I can conclude that the problem of lags is not a problem with the router, but a problem with processing tracking on the headset itself, caused by the load on the hardware, possibly throttling the processor! I replaced my old router with a powerful ASUS RT-AX82U a long time ago, I get perfect numbers when broadcasting games on quest both in the airlink and in Virtual Desktop, I have no problems with video transmission, the only problem is with tracking. The video below shows a test of the game I Expect You To Die 3, with the same streaming settings via Airlink (first half of the video) and Virtual Desktop (second half of the video). In the video you can see that in the case of Airlink there are practically no problems, while in the case of Virtual Desktop the problem is clearly visible, although the same router is used with the same settings. At the time of recording the video, the Wi-Fi settings of the router are set to AC mode with a channel width of 160 MHz. Moreover, only with this combination of settings does the airlink work as smoothly as in the video, but when setting the AX mode or the channel width to 80 MHz, the same tracking lags are observed as with the Virtual Desktop.

Today I decided to try the standalone version of Expect You To Die 3 and purchased it in the headset itself. When testing the standalone version, I got much larger lags than what can be seen in the video above. I was unable to record them on video because for some reason they almost completely disappeared when I started recording the screen with the headset and reappeared immediately after recording ended. Perhaps during recording some graphic effects are turned off or the game resolution is reduced to reduce the load on the hardware, I cannot explain this exactly. After that, I started trying to test my other standalone games, such as Resident Evil 4 VR and A Fisherman's Tale, but they worked with perfect tracking. That is, the problem was expressed only in this one game. This problem can also be observed in the home environment of Meta Quest 3, if you carefully observe your hands when moving in space.

I tried experimenting: changing the room, lighting, tracking mode in the headset to 50, 60Hz and auto, changing the batteries in the controllers, but none of this helped solve the tracking problem. Only at the end of testing, by random chance and unknown to me, did the standalone game Expect You To Die 3 start without tracking problems and run smoothly. Immediately after this, I launched Virtual Desktop and it also showed fairly stable performance. Based on all this, I draw the conclusion that the smoothness of tracking depends on the load of the headset hardware, and the load depends, firstly, on the Wi-Fi mode (AX mode loads the hardware more than AC mode) and the selected streamer (streamers such as Virtual Desktop or Steam Link load hardware headsets apparently more than the airlink integrated into the system itself). In the case of standalone games, the load on the hardware depends on the hardware requirements of the game itself. Expect You To Die 3 is apparently more resource-demanding than Meta Quest 3 and causes lags when heating/throttled. I finally urge the meta engineers to either recognize all such cases as a defect in the headset and make a replacement, or fix this problem with updates!

Just wanted to chime in and say that I'm affected by this issue as well on a Quest 2

Okay, so I've tried updating Quest to v65.

I'm now running 2.5Gbps network card -> 2.5Gbps switch -> 2.5Gbps Ubiquiti 6Ghz - 160Mhz band.
It took a while for Quest to see the Wifi network again, but in the end it connected.

I'm running Virtual desktop, H264+, 500Mbps bitrate, 90fps.
VD performance overlay is showing 6GHz, 2401Mbps bandwidth and under 40ms latency.

So far I've been able to play Beat Saber flawlessly for 10 minutes.
Before, I couldn't even finish a song because of the constant stutters and disconnects.
I'm going to try other more demanding games now, hopefully it will hold up.

EDIT: Sorry for getting everyone's hopes up, I tried Half Life: Alyx and it died on me after a minute as usual. Back to 5GHz

Tested again after the latest update, still happening! Not resolved.

Just wanted to say this issue exists on the quest 1,2 and 3 not to sure about the pro tho.

Im trying to contact meta customer support with this issue since over a month ago but they take weeks to respond to simple messages and i dont think they are acknowledging that its a software issue. they are currently(since about 2 weeks) trying to check if im elegible for a replacment wich probaply wont even fix it as i had the issue on quest 1 and quest 3 so I doubt i got two malfunctioning headsets. And it also existed on my old aswell as my new wifi router. I havnt tried seitching pcs as mine is more than enough and way to expensive to swap out

At the moment the problem is most noticeable when playing through Virtual Desktop:

When playing via airlink in AC 160 MHz mode there are almost no lags, but in AX mode there is this.
