Lowered graphics where possible lowered frame drops.
First time in-game, select Options, then LB/RB to Controls; dpad left/right to choose Control method; "2. Microsoft X-Box 360 pad 0", then B for back and now you can play the game with Steam Deck's controls.
Flawless on default Steam proton (8.0-3 or Experimental) AND on Native (Compatibility: Steam Linux Runtime)
Xbox Series controller also works flawlessly.
Game could be completed without any problems.
Played the GOG version using Heroic Games Launcher
Dex runs excellent and is a pretty interesring game.
change multiple control behavior
You need to configure controls within 'gamepad configuration' in the game launch menu. Then, flawless experience.
Configured controls within 'gamepad configuration' in the game launch menu.
Works good out of the box.
Alt-Tab works well, but the game continues to handle the mouse cursor even in background. It makes other apps/windows inaccessible while the game running. But apps/windows on the second desktop are still accessible, so desktop switching can be used instead of Alt-Tab
Completed full game on Linux, didn't encountered any issues.
Full play-through with a DS3 controller
Native version works fine as well.
