Set everything to highest quality but Effects to Low and Background Qaulity to low if you want a low 70 and average 90fps on steam deck , you could also set effects to medium if you want to lock at 60fps
Make sure those two settings are low , Background quality is just a shader effect for shadows so you won't lose much except the anime lines they add to shaders

Finished the game without any issue

Had to tweak few graphical settings to get stable 60 FPS

Runs alright, ~30fps on default settings on DeckHD (1200p) screen. Had to mess with ingame settings to get to 60fps.
Ingame settings
Graphic Settings
- Windowed Mode: Borderless
- Resolution: 1920x1200 (16:10)
- Frame rate: Uncapped
- V-Sync: Off
- Anti-Aliasing: High
- Shadow Quality: Medium
- Texture Quality: Medium
- Post Processing: Medium
- Effects: Low
- Control Config: Type C
- Character Quality: Highest Quality
- Background Quality: High
- Cinematics Quality: High
- Rendering Resolution: (Slider set exactly in the middle)
With these settings, I was able to get 60fps in the train in Chapter 0, as well as in the first Mystery Labyrinth, without too much visual fidelity lost. You may be able to set some things higher on the default 800p display.

Had issues with controller icons always displaying Xbox icons, even though I was using a DualSense controller and had selected those icons in the game's settings. To fix:
Open regedit with proton tricks. Create a DWORD key named "DisableHidraw" at
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\winebus
and set the value to 1
See above issue with controller icons. Steam Input is required to set the correct mappings (touchpad should be backlog; set touchpad to "Select Button" in Steam Input; ingame controller support sets Create button to backlog and leaves touchpad blank).
Runs great on mid-tier hardware. With resolution scale dropped slightly and some graphics settings tweaked ("Effects" is a big one for performance), I am able to maintain a steady 100-120 fps in most scenes in the game so far.

gamemoderun %command%
There are only two minor issues with this game:
- It would seem there's a custom mouse cursor for this game, though it randomly worked for me only once. I tried running this game both on X11 and Wayland, but on both I've only got my system cursor.
- Due to the nature of this game "gamemoderun %command%" is a must if you prefer autoplay instead of advancing dialogues manually. If you won't use it your PC will lock, or go to sleep during a cutscene depening on your system settings.
