Very low frame rates with Quest 3 link cable and good PC specs.

[Phrogy]

I have been struggling to figure out why I am getting such bad performance with my quest 3. I have the official link cable and good PC specs. I have tested my link cable and it runs at 2.5 Gbps. I also have a rift s that runs perfectly fine. I think I have figured out what is causing the bad performance but I don't know how to fix it. Here is my Oculus Debug Tool:As you can see at the bottom, I turned on the visible HUD and have it set on Oculus Link. There is a graph that shows the Encoder frame rate and for some reason it is not going any higher than 20hz. I think that is the problem but I don't know how to fix it. Also, when I set the mode to performance summary, my App frame rate is constantly 80 (I have my headset set to 80hz). I have also disabled Asynchronous Spacewarp and it didn't do anything. If anybody has any ideas, please let me know.

Hey there, @Phrogy. I see you've been getting some frame dips when doing PCVR on your Meta Quest 3 and noticed these dips don't happen when using the Oculus Rift S. We want our players to be able to enjoy VR to the fullest, regardless of which device they choose to use. I do have some questions for you on this.

• does this happen with a specific game? or is it all games?
• Do you have any other USB connections you can try?

Looking forward to hearing back from you on this.

It is all games. Even before I load a game the performance is not good. I have an adapter that allows my link cable to be plugged into a USB A port but I have the same results.

We appreciate you sharing your specs with us. To continue checking a few more troubleshooting steps on the list, have you tried to use Air Link? You can find out how to do that here. Lastly, have you tried to do a factory reset? If you try that option, just make sure you have cloud backup on, and you can find that information here. We are committed to continuing to explore next steps, and we eagerly await your reply!

I have tried air link and it does not work well. I just factory reset my headset and now I can't even get it to recognize that it's plugged in. I am stuck on this screen:

Nevermind, I got it to connect but the performance was the same.
