Meta Quest Link Update: Link Launch Issue Resolved

The Oculus Debug Tool doesn’t work properly! Every time I have to set it up again because it always resets to the default settings.

'Fixed', but at the cost of stability and performance with PC VR.

A real shame, as I had noticed constistant and worthwhile incremental improvements in PC VR performance over the past few months, and now all of those gains lost due to slovenly testing and release management.

Fewer releases that were properly tested with be prefereable to rushing new functionality out for most users.

Yeah... connection issues seemed to be resolved.
But its choppy as hell after starting a PCVR App/Game.
Performance looks OK, 90fps on PC, 90fps in the quest... but no, not usable.

Before 10:90 to get a connect but afterwards everthing was OK.
Now, 100:0 to get a connect but afterwards everthing went bad.

So please do another update to the Meta Horizon (Windows-)App and correct this!

It shuold be something with the base driver, because also SteamLink is affected.
Didn't test VDM (VirtualDesktopMobile) if its the same tho... no PCVR now!

Hi, thanks for gathering this information.I need either a concrete solution or at least a clear timeline/ETA for a fix. I’ve been blocked for over a week now and unable to work on my projects because my workflow depends on PCVR (Quest Link/PC Link) and multimodal hand tracking (hands + controllers), which were broken by the v83 update.This is a critical regression for developers. If a fix cannot be delivered quickly, then the software should provide an official way to roll back to the last known working version (the version before v83), or offer a stable channel/build that restores the previous behavior.
Please advise on:
Whether a fix is already in progress and the expected ETA, or
An official rollback path / stable build that returns functionality while you work on the v83 fix.

Are your settings still the same after the update?

Yes, settings have not changed in either the Meta Link App and Game

Is the issue happening with Air Link, USB Link, or both?

USB Link

Describe the performance issue - and is it consistent? Does it normalize after a while? (e.g., stutter, frame drops, visual artifacts). 

Whilst playing ACC this evening I experienced lagging and black screens which resulted in multiple crashes in race.  The race was 40 minutes long and the issues persisted for the entire duration.  

Abdallah.hilali​  Sorry mate but this is now unacceptable imho.  Not only do I lose seeing my controllers in VR dash, many meta-link apps will not startup and/or crash (eg. nature treks and glider island).  I tried opting into meta-link pc app beta (v85), not headset beta, and this did not make any difference.  Using Virtual desktop still works ok but these same meta-link apps still crash.

Everything was working fine a few days ago with latest non-beta v83 using both my Q3 and QPro sith Link and Air Link.  So, pretty obvious that there is a serious problem with the latest non-beta v83 meta-link pc app.  Please try to get your meta engineers to fix this issue and/or, in the meantime, rollback the meta-link pc app to an earlier version.

I'm now starting to appreciate my +6yo Vive Pro1 (with AMOLED screens, etsy lens mod, 2x2.0 base stations, and index controllers) more and more, lol!!!  Thanks, and cheers.

Hi all, 

Updated 2/13/26

Our engineering teams are actively investigating this issue and would appreciate your help in verifying some tests. If you’re interested, please check it out here:

Help Needed: Link Performance Check | Meta Community Forums - 1366142 

Updated to add two more questions. 

Thanks for providing these details. 

Windows recently released a security update, and we believe it may be related to the streaming performance issues. We’re actively investigating and working to confirm the root cause.

To help us narrow this down, we’re looking to hear from anyone who:

1. Had no issues over the past week, but recently started seeing frame drops or other streaming problems.
2. When was it working and when did it stop working as intended?
3. Share your setup details, and thanks to those who already have. :)
4.  Which Windows Quality Updates patch are you on? 
5. Did you recently install the Microsoft Windows security update -KB5074109. 

Thanks!

I am unable to confirm if this issue has been present during the last week as this is the first time I have been able to use my headset following the previous issue.

My setup is a Quest 3 via link cable with a Intel I5 14600kf, 32 gb DDR 5 RAM and a RTX 4070 Ti GPU.

I can also confirm that the KB5074109 windows update is installed.

First signals about bad performance  in this stupid v83 pc  update was about 2 months Ago when you relase it in  PTUchannel  when meta change name app from oculus to Horizon . I saw  you was never interested to give even Answers to peopls  who gives you a Signal about losing performance in yours previous threads about 83 update … . In my case first „forced” relase of v83 was before christmas .i had to Cut off my bitrate from 960 to 500 mbps to be able to play smooth . After NEXT few update i had to cut off  bitrate more and more due to stuterring . But now  it is look like trash. And my quest 3 is unusable for me i am interested only in fly sim . 
i see you look very surprisd about this situation but i don belive in your company no more . Why are you dont read a your own thread ? Why are  you dont do nothing  since  first buggy  relase v83? Why are you try to folish us  about Windows security update ?  I know only one , your developers dont  know what  they are doing … thats the fact . But i think i know solution for this situation . You should  fire yours developers and you should hire one guy his name is (Mbucchia developer of openxr toolkit ).  I am pretty shure he can find solution for your mess .
