Hello Xypheron, it's total carnage here too. I was on V72, I only play Iracing with this Quest 3.
Everything was going great, to avoid being disturbed during my races, I always turn off the Wi-Fi.
Yesterday, I put my headset in, turned on the Wi-Fi, first it showed me V74, then it rebooted, and then I saw that V76 was available, so I did it too.
Then I went into my sim, activated Link, and there, I barely moved my head, and there were black artifacts, huge lags, almost impossible to exit by clicking the "leave Link" button.
I searched until 12:10 AM yesterday, I was going crazy!
Here I am, coming home from work, new update in the app and in the Quest, I tested, it works again!
I restart my PC, install my simulator, activate the link, and here we go again, full of lag in the interface.
I5 13600K 4800Super 32GB of RAM, official Oculus cable for a fortune!!!
Why did I upgrade to V76 when I'm not in the public test (PTC)???
And there's no way to go back to V72, that's pretty stupid too!
