Perfecto, instalar y jugar
No he tenido que hacer nada, sólo instalar y ya se pudo jugar sin problema.

I am experiencing very low FPS on the lowest settings even though I have a new high-end PC.
Runs great at cinematic settings on Windows.

A fun follow-up to the first Life is Strange and an interesting setup for more sequels that ran better on Linux than it did on Windows.
Ran better and more stably on Linux than it did on Windows, where I was plagued with sound bugs and asset breakage. Worked out of the box with no proton changes.

Installation went flawless, game started and played.
Some mission critical NPCs were invisible
I've heared that people with 4090s even struggle to play this game with fluent FPS, I have not seen any issues yet, even while in any of the timeshifting modes. As of how the Steam Deck handles this game, I wouldn't call it unplayable, but I wouldn't call it pleasant either.

Works out of the box, completed a full playthrough without issues
With maxed settings game is demanding and would run at around 45-60fps @1440p on my setup. Some scenes when using the time line "echo" ability have about a 30% performance drop.
Note that I am using a 6.6 LTS kernel, because of rare random crashes with recent regular kernels with the 7900 GRE.

Doesn't start - only shows an unreal engine chronos fatal error popup
I tried to change the proton version from Experimental to Hotfix, 9-04, 8, but it doesn't help.

Disabled postprocessing and blur for sharpness, what lower GPU usage
Blurry and washed, but it's sold with this as preset.
Based on blur postprocessing of the graphic.
Maybe people like blurry graphics, but HD should look at such.

Wenn Max mit dem Puls in die alternative Zeitlinie blickt (E Taste) fallen die FPS unter 30 Bilder/s. In dem Moment eigentlich nicht Spielbar.

rarely some graphical issues

lower graphics settings
doesnt run well on the steam deck (not because of linux but because it doesnt have enough power to run this demanding game) but you can get a playable experience on lower graphics settings
Everything works perfectly and exactly as it should, no problems here

Works out of the box for me as i always use the latest GE-Proton as default.

Some sections run at 90 FPS, some sections barely hit 60 FPS.

Some lighting artifacts a few times, nothing major
Spacebar didnt work first time i played, but seemed to work fine later

when using second timeline overlay the framerate dropped significantly. To me about 30-40 fps
with default proton the game would not start. It was stating some unreal error

Works without tinkering. To get acceptable frames tho, graphics have to suffer quite a bit.
sometime Audio sets in a millisecond after the character started talking
Worked perfectly all the way through

Had sometimes only got 10fps for a couple scenes, but this could be my nvidia 3060 not being optimal for new games tho.

Minor graphical glitches such as with scenes being overly bright, which seem to be reported even on Windows PCs, so presumably just early unpatched game code, nothing Proton/Deck related.
Again, also reported on Windows PCs, so just the result of early unpatched game code, I think.
The Steam Store page Steam Deck compatibility status is clearly just wrong with its "unsupported" claim. Luckily, I found a community forum report from someone saying it worked fine on Deck with Proton Experimental. I tried it and was able to complete both early release chapters with no real problems. I haven't tried non-experimental Proton. But, no idea why Steam thinks it's "unsupported", when it is perfectly playable!

Usually running really good with 60 FPS on high settings. Really bad performance tho (5FPS or less) as soon as i activate Max' time powers. When deactivating Max time powers, everything runs smooth again on 60 FPS.

Runs fine with default Proton
Manually adjusted the graphics settings to improve the frame rate
The only minor issue I've had was that I couldn't take any screenshots through the Steam shortcut (maybe because of the "Advanced Access"?)
