I would just like to see more games be a bit friendlier with settings. Give me some real potato settings or focus a bit more on optimization so I can play stuff without having to futz with settings so much.
Issue not necessarily appearing on the Steam Deck but it would benefit from it as well - better handling of mixed input from a controller and mouse. I have a Steam Controller and prefer to have it simulate a controller in FPS games but to have the right touchpad work as a virtual mouse to ignore in-game acceleration curves and deadzones.
Some games handle it well, like Cyberpunk 2077, some games like Grounded tend to show keyboard prompts whenever it would detect mouse input but still function correctly.
If I'm not mistaken Borderlands 2 would drop it's UI controller layout whenever a mouse input was detected, which can probably be skipped by using layout switching/overrides from Steam Input.
The worst offender so far is Hunt Showdown, where the game freezes for 0.5 s when it detects mouse input, even if it's a physical mouse input.
All of my testing has been conducted on Linux, not sure how it behaves on Windows
How are you running Minecraft? I'd recommend Prism launcher, and then installing the Controllable mod. It's excellent - updates the UI and controls to match the console versions of Minecraft.
Ok, I know it sounds crazy but I actually quite like this set up I made for playing cataclysm dda using onboard steam deck controls. There are four pop up menus of keys that map to left joystick, left touchpad, right joystick and right touchpad. The remaining center two columns of the qwerty keyboard map to the rear four buttons and two shoulder buttons like they are on the qwerty keyboard.
(No mouse because it is cdda you don't need a mouse.)
There are three rings, the wasd ring which is a natural spatial mapping at this point for pc gamers (push the s down, z and x get pushed to the sides and become diagonals), the vim ring which unfolds the classic hjkl vim navigation controls (with diagonals) into the natural spatial mapping (might actually help you learn basic vim controls lol idk) and the numberpad gets its own ring/3x3 square but retains number row shift functionalities. The fourth menu has keys on the righthand side of the qwerty keyboard basically represented as they are on the keyboard and houses mainly menu/ui navigation stuff.
Maximally little unnecessary memorization and it works, as nonsense as it sounds.
Mostly my problems with Steam OS (and windows Big Picture Mode) is the seeming lack of options for controllers that aren't Xbox or steam controllers. Steam used to be excellent at this but more recently in Windows 11 (and in Steam OS) the controller support is great when it works but if you want a more granular experience it's just not there). I somehow have less settings and options for controllers support than I did in Windows 10, and the way it detects controllers cannot seemingly be changed. So if you're like me and own an SN 30 Pro2 controller with back paddles, you can't configure them without jumping through a whole lot of hoops. And in game that means that you're just not going to be able to use them which is a minor inconvenience but one that's been bugging me.
