Performance in window mode is severly degraded; Fullscreen works without any issues
The game only works with GE-Proton8-32. I have tried several other Proton versions (Hotfix, Experimental, 9,8,7, various GE9 and GE8), which ultimately caused Denuvo to lock my install for 24 hours. Thus, make sure to not switch Proton versions too often, as each seems to count as individual install. With GE-Proton8-32 however, the game runs amazing. I had lots of issues with it on Windows, like performance drops and full crashes, but have yet to encounter any of these under Proton. Surround sound is hidden behind a setting in the games audio menu. Otherwise, I did not need any additional launch options besides gamemoderun.
The game had severe performance issues playing in Windowed mode, however it performs perfectly fine in Fullscreen
Steam Overlay reports the framerate incorrectly, it gets stuck at 50 even if you cap the game to 30 FPS. The game would also outright refuse to launch if I included any launch options at all
It performs about the same as it does on Windows for me, if not maybe a little bit faster in some aspects. The framerate is perfectly stable with the graphics settings maxed out; aside from having to run it in fullscreen mode to get a stable framerate, I have no complaints about it

FPS drop on few areas and combats.
By default, the game only show black screen.

GE8 does not detect controller (both for steam deck and Bazzite)
Newest GE (9-22) does not work (can't see main menu). Old GE (8-22) does not detect controller. Runs perfectly with 9-5.

the game only loads for me if i set it to proton GE 8, GE 9 and experimental doesnt open the game and the launch options for me are required if i want to get past the opening movie
ge 8version cant use controller
com o Proton-GE ele rodou apenas da versão GE-proton9-9 pra baixo
gamemoderun %command%
Toggling fullscreen could trigger or solve performance issues, without any reliable pattern.
Having tried up through GE-Proton-18 down to GE-Proton9-9, the latter is the latest version that gets past loading screens without missing audio for dialogue.
Must use GE-Proton 8.25 version, and you don't need to add any launch option. If you encounter other problems, refer to others to add launch options.
the game functions properly with Proton 8-25. the rest of the versions failed to advance beyond the black screen.
occasional crackling of sound
Doesn't start with current Steam proton.
gamemoderun %command%
Heavy lag whilst not in fullscreen mode
Followed someone else's reccomendation and I can confirm ProtonGE 8-25 works well aside from minor issues with windowing.

If you don't use a proper version of GE-Proton after the little hat you'll have a black screen. I haven't tested it much but it seems to be playable, in the proton github issue there is talk of graphical artifacts but I didn't notice any so far.
Wouldn't start for me
gamemoderun %command%
Tried GE9-15, GE8-25, Experimental and regular 9, with or without gamemoderun %command%, all to no avail. It spent ages doing the vulcan shaders the first time, but then just flickered black for a moment and exited. Every subsequent try just did nothing for 4-5 seconds, flickered black, then exited.
Without the right Proton version the game won't even procced to the logo screen. No start option needed aside from that it runs great on the Deck OLED. Not running with the newest Proton GE versions, older like 9-5 worked fine
gamemoderun %command%
Only able to full screen once through first boot.
Game is currently broken when using the latest GE-Proton (version 9-15). Newest working version is GE-Proton9-13 however this has the cutscene audio bug noted in previous versions that was fixed in the late GE-Proton8. The prior launch option fix for the audio does not work with current versions.
Recommended that you set your compatibility to a GE-Proton8 version to get working. I have used GE-Proton8-25 as this was noted as working previously with full cutscene audio without the need for launch options besides "gamemoderun %command%". Can comfirm that so far the game works flawless with this and "gamemoderun %command%" added.

Must use proton GE 9-9 specifically, at least for me. Newer versions don't get past the loading screen. Good luck!

Windowed mode had graphical glitches
Without ProtonGE it wouldn't work, but after installing ProtonGE, it's been almost flawless.

Anime cutscenes always start to freeze if the resolution scale is high, even running at 60 fps during combat
You won´t get past the first loading screen with Proton 9 or Experimental. Use GE instead

The game runs well on the OLED deck but take care finding the Proton version that works for you (details below).
The antialiasing seems to make some text look funny.
Some of the more recent reports said they could get the game working on various GE-Proton8 versions. I could get to the title screen with these but the Steam Deck controls were unresponsive - could only use the touch screen. I've only been able to get the game working with GE-Proton9-5 (the latest version at this time is 9-10 and didn't work for me).
Also beware, trying too many Proton versions will lock you out of launching the game for maybe 24 hours. I tried maybe 5 Proton versions and got locked out - needed to try again the next day to find the version which worked for me.
O jogo não roda normalmente via próton experimental ou qualquer outra versão, mas roda tranquilamente com o GE 9-9.
gamemoderun %command%
O jogo trava se a escala de renderização for muito alta (mais do que 1,5)
Por alguma razão o próton GE mais recente (9-10) não abre o jogo.
Proton experimental couldn't reach the main menu, ProtonGE8-32 would recognise gamepad. using ProtonGE8-25 fixed everything
Shaders compile when I hit play, but get stuck on initial loading screen with phantom theives logo. I can't get to main menu or anything.
Doesn't run for some reaon after trying a bunch of the suggestions on here.
Game doesn't boot past title screen; you're lucky to get past the opening movie
Sometimes the game will crash after the W-Force logo. Sometimes the game will crash after the first Phantom Thieves loading logo. Sometimes the game will crash after selecting a save file. In any case, the game won't load in.
You have to disable anti-aliasing
You have to change to the newest Proton GE version (I used GE 8-32). The game will not launch without Proton GE. After that the game runs completely fine with 60fps
Use ProtonUpQt and get Proton GE set up with 8.28 and the game will run fine. Personally, to combat some of the intense aliasing from the game's awful engine, I disabled anti-aliasing in settings (intuitive), and forced the resolution to 1080p. It's still not good, and you now don't get 60 FPS all the time, but it's better than 720p
DO NOT USE Proton GE 8.27. I experienced severe battery drain and the Steam Deck misreporting its battery level, leading to unexpected shutdowns at 40-50% alleged battery level!
Use ProtonUpQt and get Proton GE set up with the latest version and the game will run fun. It does seem to absolutely suck back battery though
