SargonAelther: Oh it's great as a console, especially if you live entirely within Steam, but as a GOG user who cares about achievements AND wants the handheld PC to act like a proper PC, the Deck's been giving me nothing but trouble.
If I was concerned about my budget, I'd get a ROG Ally, at least Windows has better touch support (On the desktop) and most apps run without tinkering. I can afford to by indie device though so I go for GPD, because they are keyboard-obsessed. And heck, this Obsession may just save them, because I think the ROG Ally has just made Aya Neo, OneX and AOK obsolete lol.
Weird. As a GOG gamer who cares about achievements, the thing works great for me. I installed Galaxy as a non-Steam game, then I install my games through Galaxy. I add a non-Steam game, tell it to use the same compatdata prefix as Galaxy, and point the installer to Galaxy, run game id xxxxxx. Games work in desktop or gaming mode with a long loading time since it has to load Galaxy first. But I get cloud saving and achievements (unless a game *coughBG3cough* doesn't want to support cloud saving) just fine. Of course, I may make different Galaxy installs for games that require different PROTON versions to keep from mixing the bag in the prefix, but the beautiful part is I haven't come across any games I want to play on my deck that don't work with the versions of Proton I'm running.
