tried various proton versions
crashes on first or second campagn battles while lading battlefield

Set the controls to more closely match the XCOM: Enemy Unknown controls.
Locked the FPS to 60. That gives about 2 hours.
Menu text is quite small. No easy way I can see to resize it.
Before switching to GE Proton, the game would crash occassionally. Switching to GE Proton fixed this entirely.

Double click bug. In certain menus the game interprets one click as two which makes me buy things twice or unable to select certain options. This happens to me regardless of input hardware, version of Proton, modded or not. If anyone knows of a fix, please DM me.
Except for the double click bug (which admittedly only seems to affect me) this game runs great even with 139 mods active through the Alternative Mod Launcher (AML).

Action hotkeys to save time
TDP and 40FPS cap. about 3 hours gameplay
Works fine ootb, adjust to save battery. some UI elemnts can be small if new to the game
use back grips to map four number keys (2,3,4,5)
Steam version runs fine on deck, no further config needed, uncertain if its running native or proton. However the Epic version is not playable (unable to move any charactors)
I had various issues (black screen, unable to control characters, etc) until I switched to GE-Proton7-38

Ive download the game and boot it up, I got to the tutorial mission couodnt move any operator. I start it back up and now when I get to the tutorial mission, I am met with a black screen all i cam do is move the mouse cursor. Ive tried numerous things, Ive factory reset my steam deck, different proton/proton GE, wine proton, and deleting the files/app (Heroic Games Launcher). Any tips would be helpful please and thank. (sorry for any typo or grammer error is b/c I'm typing on the steam deck)
(HGL) = Heroic Games Launcher btw never had graphic issue Ik thats not the reason.
I was hopeful the game would work since I played a bit of it on my desktop also running linux. However upon loading my save I was unable to order any operative to move anywhere.
In-game settings turned to low, framerate capped at 40 through Steam Deck options, brightness slightly lowered. Battery life seems roughly 2-3 hrs.
2K Launcher sometimes causes issues on startup.
Plot-related text like character subtitles are very small. Menus and buttons are good enough but also small.
Framerate is inconsistent, often not keeping at 40FPS. Menu performance slow.
Controller support is not native - most community profiles still rely on moving the mouse cursor with touchpad.
