Laggy V81 & PTC, V83 Via Link

Hi

Since installing V81 my Q3 has lag in the form of the screen looking like it has a low refresh rate when turning your head, noticeable especially on bright text and objects, in racing sims it becomes nauseating. The issue only happens via the link cable with meta software and at 72, 80 and 90hz. At 120hz the issue is resolved but the image appears softer with less clarity than any of the other refresh rate options, different resolutions don’t make a difference and using 120hz can tax the PC too much. 
Virtual desktop and steam via WiFi work fine but I haven’t tested it with meta WiFi connection. 
I have just joined the PTC and installed V83 and the issue persists.

Any one have this issue, any one understand how to resolve it ?

btw it’s not the cable as I have 2 too play with, desktop and headset both have matching PTC software

    I have managed to resolve the issue. Changing the encode bitrate (mbps) in debug tool from 960 to 400 has stabilised the headset and the lag has gone. 
    I have been able to run it at 960 for endless versions until V81 came out, don’t understand what has changed in 81 but it seems to have effected that perticular setting.

    have you checked that the meta quest software isn't now detecting your usb3 port as usb2 ?  I have that problem and opened a thread on it as well... waiting on meta to fix

    I have the same problem; my cable is recognized as USB 3.0, but I experience a lot of lag in games.

    Hi, yeah I did a search on here before posting the issue and it may have been your post I read, I did the USB test and it came back as USB 3 so not that unless it’s reported wrong.

    If only meta would allow roll backs

    I have stable usb 3.0 connection with 2.9-3.1 Gbit/s on Quest 3, but after update I have constant stutters, they just broke all stuff with this update

    I found that after the last Link update, some of the internal Link settings have been changed. Have you tried using the OculusDebugTool to check your Link settings? I had disabled Asynchronous Spacewarp and Sliced Encoding, but the update re-enabled or changed these settings and caused severe problems for some of my PCVR games until I set the settings back to what I had previously.

      Cheers, not yet, I will check this later as it’s really the only place I haven’t.  
      I always disable ASW manually on boot as it likes to default on, the sliced encoding I’ve never changed and will try reducing the bitrate from 960.

      if it works I’ll update this thread

      I get good AirLink performance on an old wifi 5 router using the 5Ghz band with maximum render resolution (1.4x) set in the Link PC app and 72Hz refresh rate, with the default headset bitrate of 200. I haven't noticed any difference when using the official USB cable. There's a very obvious increase in visual quality using the increased render resolution, so I don't think the 200 bitrate is bottle-necking the Link connection, so it's probably not necessary to increase the bitrate too much.
