I've been blown away by being able to finally, at long last, game on my linux machine. Between emulators and Steam's Proton, I'm rarely if every needing to boot into W$ just for games. That said,while I can play the gamepass web streaming thing, I don't know if there is a way to use gamepass locally with Proton. Is that possible?
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.
Someone else ITT suggested gpu pass through, but I haven’t given that a go. Otherwise yes looks like the only option is rebooting into the windows partition.
