For those struggling with finding the directory path on Linux for HF installation, the file browser will path with / while the system will path with 'backslash'. To find your system directory path for the game, open the launcher or game, then launch the Linux task manager (also called system manager) (btop++ on Deck). When clicking on the game task, it will also show the true directory path.
Limit to 30 FPS
Some drops to 19 FPS.
Works fine using Proton Experimental otherwise game doesn't load. 720p is higest res option. Mostly stable at 30 FPS but some areas of game have a big drop.

Add DLL override "winhttp (Native, Builtin)" in winecfg for mod support / HF Patch. Not required for base game.
Mouse cursor keeps automatically moving to the right on newer proton versions, does not occur in 5.13-6
All works fine out of the box.
The game runs out of the box with proton 5.13-4.
The HF patch also runs without any problem.
When installing the HF patch please make sure you entered the correct installation path of the game.

If you want to enable mods and languages support, you need add "winhttp (native, builtin)" DLL through winecfg.

Run ~/.local/share/Steam/steamapps/common/AI-Shoujo/AI-Shoujo.exe thru "Games/Add a Non-Steam Game" and "Force the use...": Proton 4.11-13. Crashes with Proton 5.0-4.
Turning off shadows/SSAO/bloom/SSR in graphics options significantly increase performance
