(as set by Heroic Launcher when adding the game to Steam ... nothing else special/custom)
I'm using Proton-GE just as a default at the moment, so it was the first thing I tried... Gonner might very well also work fine with other Proton versions/variants.
Assigned Tab and Shift to back buttons. Also re-bound some in-game controls to use the keys emitted by the face XBY buttons.
The game's video settings don't offer the native Deck resolution as an option; but the (extremely stylized) visuals look fine at the default 1920x1080 setting.
Put zoom in/out on back buttons, changed left trigger to rewind, changed right trigger to A-button.
Used GE in order to be able to see the little videos in the building selection popup dialogs.

As per https://nickdablin.wordpress.com/how-to-play-thief-fan-missions/ I copied in the files for TFix Lite; this is mandatory.
I then tried running the game with GE-Proton8-25 but couldn't see the cutscene videos, so I rolled it back to GE-Proton7-50 and that worked fine.
Audio also worked fine at this point, but (following another comment here on ProtonDB) I also installed the OpenAL files from https://community.pcgamingwiki.com/files/file/2131-newdark-openal-soft/ and enabled OpenAL+EAX in the game's settings. No sound problems after doing that but I haven't yet done careful A/B testing to see how it helps.

I got "T2Fix 1.27e (without mods)" from https://www.ttlg.com/forums/showthread.php?t=149669 ... version 1.27e was the latest at this time & that's what I used. I used ProtonTricks to launch a Wine shell in the game's prefix, and run T2Fix_1.27e.exe in there to modify the game directory. In the T2Fix wizard I chose the "High" preset for Video Configuration, and checked all three Installation Options (OpenAL Soft, libmp3lame, clean up install directory).
