The fact is that Steam Deck runs on Linux and, in order to run games, it needs to create files for each game that emulate the Windows environment. Steam Deck also creates a shader cache, which, in turn, also eats up a lot of main memory. My advice, leave the built-in memory for the system and do not put games there. Over time, when you want something more and start experimenting, you will need the built-in memory to install all sorts of add-ons that will improve performance and gaming experience. Get ready to spend a lot of time on all sorts of settings. Spending an hour tweaking the graphics, then another hour tweaking the controls (not always of course, but quite often) will be a common thing for you. If you're a console player, this might be a little annoying at first. Outcome: Can we say that Steam Deck will appeal to everyone and suit everyone - definitely not. We can say this: Finally, PC gaming has become more convenient and enjoyable. I'm happy with the cookie. At the end, I can play PC exclusives, and even in a portable one.
