Change to GE-Proton, run setup when launching game, set resolution to 1280 x 800 and click fullscreen, change nothing else, hit OK and enjoy. No need to mess around with files or anything.
Changed the AppSettings.InI file as follows

I changed the MinScreen and ScreenWidth, ScreenHeight lines.
In Config.ini, I cranked the framerate to 60. I changed VSync to 1 to stop screen tearing.
After making the changes in AppSettings.Ini and Config.ini be sure to set Game Resolution in Steam Deck mode to 1920x1080.
Unknown(< 1 hour with Proton)Game automatically runs in windowed mode with no option to change it. Issues with the mouse jumping around, but I think that might be an issue with the game. Runs flawlessly with controllers, no artifacting at all throughout the first level.
