These machines are really amazing if you know how to properly set them up. Bios balanced profile, 24 GB RAM and 8 GB on video or 32 GB RAM and 16 GB video if you mount 48 GB RAM DDR5 and you're ready to go with the FSR quality preset on medium-high settings, 1080p 60Hz or even 1440p 120Hz. Better and cheaper than a PS5 Pro for sure lol

Sometimes the luminance of light fixtures will get very blurry. However aim or look away the blur goes away.
A toggle option for HDR is in the settings, but won't let you tick to enable with just the deck alone undocked.
The game has plenty of wiggle room to experimemt with graphics/performance, but you can just jump in smootly without adjusting. Has FSR in the in-game settings already.

Its enjoyable experiece with few bugs. game ran nicely with max settings without motion blur and depth of field
game-performance mangohud %command%
Sometimes audio might go haywire for few seconds. Not really a big deal since it didnt happen only few times
It crashed once during playthrough
Got stuck few times so i had to reload save
Works almost flawlessly
Really good on deck. Settings can be changed to mostly high and maintains 30fps no upscaling.

Great horror survival game. The loading pauses and occasional bitmap application delay do not affect the enjoyment of playing the game.
Most of the small text notes have the option to be read by the actors out loud. Most of the text you can also pull up later and it displays as regular text. A few areas I used the magnefy key combo on the Steam Deck
Transition to some cutscenes gives low-res effect for a second or so before going to normal high-res. A few times when entering a new area the walls are missing their high-res features for a moment before all the bitmaps are applied to them.
Load between areas can pause a second or so at times. Loading before some cutscenes, or at the end of cutscenes can take 2-3 seconds. Luckily no slow down, stuttering or pausing during game play.

Game launches with with the "Epic" graphics preset on by default. Unless you wanna run FSR on Performance or Ultra Performance, you are better off using the "Medium" preset with Anti-Aliasing set to High and FSR off. FSR is blurry even on the Quality preset and introduces artifacts.
Medium at Native with High AA can peak above 40-50 FPS in some areas, so those looking for a 40FPS cap should be able to achieve that with the selection of graphical options available. This configuration typically sits between 15w and 20w, with 16w being the average. Spikes above 20w can occur when entering a new area.
There are some traversal and shader stutters, and this is an issue with the game itself, even on a Windows PC. Patches and the Deck's pre-cache have eased the stutters since launch, yet they still occur occasionally.
Additionally, the resolution and brightness settings are saved on the cloud. I.E. if you swap between your PC and the Deck you will have to alter these settings before playing.
In-game V-Sync works well if you are concerned about input latency. I recommend enabling it and "Allow Tearing" in the Deck's Quick Settings for a smoother experience. The in-game frame-limiter, however, has issues with frame pacing, so cap the frame rate in the Quick Settings.

Works out of the box with default Proton, completed a full playthrough (game version v1.02)
In the games graphical options I recommend setting "Volumetric Quality" to "Epic" or lower, even though you get a good framerate. With the "Volumetric Quality" set to highest "Cirematic" setting it appears to cause a slight jittery feel looking around.
In the later parts of the game there are a few minor bugs. Happened a couple of times getting stuck on walls/objects. And things like enemies and random objects glitching out. But these issues are not Proton specific.
There can be slight stutter entering new areas, but not at all as bad as I have seen some people experience on Windows. Game appears to actually be running smoother on Linux.

stuttering

gamescope -W 1920 -H 1080 -f --force-grab-cursor -r 60 -- %command%
I suggest uncapping the in-game FPS and use vsync with gamescope otherwise the camera movement seems to stutter. (I tried without movement blur)
Just started, I'll keep updated if I find any problem/must-fix

Very well optimized, runs on my hardware between 60-80 FPS (sometimes in cutscenes drops to 45). Works with Proton Experimental and with GE-Proton9-1.
