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?
Some time away from the internet might help to clear your delusions.
