I’ve heard that there are several ways to get other game services on the deck. In a video i saw they used an app from Github called NonSteamLaunchers to install Epic Games Store, Battle.net, EA App and some others through Proton GE. Seems easy enough but what are the drawbacks of this? I guess some games might not function well through Proton? Are you at risk of getting banned from the services for running them through Proton?
As for PC Gamepass, am I correct in guessing I need to install Windows to use it (I do not want to stream games)? How well does dual booting work on the deck? I read that official support for dual booting is coming in the future, what difference does that make from current dual booting support?
Gamepass works via cloud streaming. Microsoft has instructions on how to get it working.
To download and install gamepass games, you’ll need to install windows
Not sure why you got downvoted but the Microsoft way through edge is working perfectly for game pass
Yep. They even have instruction on how to get the banners/logos into the Steam UI.
The cloud streaming is actually quite good and I have played quite a few games that way.
