There is no current game I want to play that doesn't run on Linux. Valve really has done an amazing job with proton and getting games to work as well or better on Linux.
Now, that said, I am not big into competitive multiplayer, so take that into account. Anti cheat is still a problem since most of the current ones need permissions that are not normally given on Linux.
I am trying to think of things that are difficult for using something like Linux mint vs my last Windows install. If we are taking about doing a full, clean install of both, I think my last Windows install was way worse.
Mint installed and just detected everything I was using without a problem. I had to tweak some minor things to get it to display on the 4K TV I am using in my living room, and there are still some games that don't play nicely with Linux.
The Windows install, on the other hand, required me to get drivers for the video card, WIFI, and a few other things to get all the hardware to work right. Then getting it how I like it took longer than I like and I had to visit multiple sites to get all my preferred software.
That doesn't explain why already established products are ditching things like plainly visible scroll bars in products like Microsoft word and other content viewers.
You can kinda make it bend a bit to your whim. While it is technically immutable if you don't mess with it, it does have everything necessary for using pacman. It just all reverts next time steamos updates. Anything you install directly through the discover portal is permanent, but it does technically have access to anything in the pacman repos as well.
I unlocked mine long enough to download neofetch and take the screenshot for this. It'll revert back soon, but I only needed it temporarily for imaginary internet points. :)
Anyone here on Steamdeck?
My understanding is that it is working much better now than a few months ago. I haven't actually put it to the test yet, but it is on my list of things to try once I have time to set up my index again.
