It might be possible, but it won’t be good. There isn’t a great low latency way to stream video on Linux outside of Steam Remote Play, which would require another PC. You’d be better off grabbing a dock off Amazon and using a cable. You can use FSR to upscale your game to 1080p too.
I’m assuming there was supposed to be an image with this post
If you have wifi and LAN then yes, but you made it sound like no connection at all. There are no games that connect over bluetooth. This isn’t a console like a Nintendo DS, these are normal PC games made with PCs in mind not handhelds.
No games are going to have that, this is basically a laptop with a built in controller.
Don’t buy Garfield kart. If you want a native kart racer, download SuperTuxKart from the Discover store in desktop mode. It’s 100% free and pretty fun to play. The character models are hit or miss though…
Honestly Proton has gotten so good that as long as a game doesn’t have anticheat I’ll just buy it and 99% of the time it’ll work. I use linux exclusively on both my Steam Deck and my desktop gaming PC (Ryzen 5 3600 + Nvidia RTX 3060) so basically every game I own runs through Proton
At the moment, Steam Workshop mods are easy as pie but Nexus mods are hit or miss. However there is a new Nexus mod installer being worked on that will supposedly run on Linux (and by extension SteamOS) so that may make Nexus mids much easier to install.
