That rate limit is insanely low, even for verified. I’m not verified, but I hit the limit in like 10 minutes of very distracted usage.

Would be interesting to hear otherwise, but my understanding is that there is no way to use gamepass inside linux. The xbox app for windows is super tightly integrated with the windows store, so i don't think there is a way to get that running via proton.

I still dual boot, although at this point its more rare for me to boot into windows at all. I had some trouble with diablo 4 on linux for example, so I've been mostly playing that in windows.
