I don’t know what the problem could be.
I’ve attached Visual Studio to my Oculus Quest via USB and have about 7 breakpoints setup. For some reason stopping at one of them, no matter if it’s the first or one that’s just a couple of lines later from the previous, it takes ages to hit. Literally a minute for each breakpoint.
After a couple of the and a few minutes passing I chose to stop debugging. The app on the quest stayed frozen and you could see the 3 loading dots a little bit.
Putting the headset on and off causes them to animate for about half a second but then freeze again…
What causes this to be so slow? It’s USB…
Ok, that’s a little embarrassing, but I managed to install the wrong apk for a whole day, therefore getting VS out of sync with the installation and not hitting any breakpoints that way.
So, make sure your code is in sync with your installation
