The reality is that Steam Deck is a Linux application, and in order for it to be able to run games, it needs to generate files for each game that imitate the Windows operating system. A shader cache is also generated by Steam Deck, which, in turn, uses a significant amount of the computer's main RAM. My recommendation is that you should not store games in the system's built-in memory and instead keep that space free for other purposes. After some time, when you decide that you want something more and begin experimenting, you will need the memory that is already built into the system in order to install a wide variety of add-ons that will improve both the gaming experience and the performance of the system. Prepare yourself to invest a significant amount of time in adjusting the various parameters. It will become second nature for you to spend an hour adjusting the graphics, followed by another hour adjusting the controls. This won't be the case every time, of course, but it will happen fairly frequently. If you play games on a console, you might find this to be a little irritating at first. The end result is that we cannot confidently predict that everyone will find Steam Deck appealing and that it will meet their needs. We are finally able to declare that playing video games on a personal computer has grown easier and more pleasurable. I'm pleased with how the cookie turned out. In the end, I can play PC games only available on that platform, even on a portable device.
