En steam deck, por la resolución no se puede activar el filtro VHS, piedes forzar el uso de 1080p para hacer uso de este filtro, pero baja un poco el rendimiento en algunas zonas

TDP limit 10W

Played almost the entire of my playthrough on my Steam Deck without any issue, outside for the framerate being a bit finicky, since in some rooms the framerate drops from 60 to 40-50, but this is due to the graphical settings being set to the highest quality.

during random rooms the game will lock itself to 40fps. sttings and proton version does not change this

Turn off reflections. Huge FPS boost in certain rooms. Game capped to 60Hz for battery saving, stability and quiet fan. Completely stable 60 FPS at otherwise essentially base settings (1280x800 resolution, Film Grain turned off due to personal preference).
Capped to 60Hz.

Disable Reflections and Volumetrics for stable 60 fps and average 9-10w usage

Turning off relections in the game settings is no longer a conern, however it is still recommended for mostly stable 60 FPS, otherwise keep it on and change to 50Hz from the battery perfomance settings (it will run between 30 - 50 FPS).
Change Frame Limit to 50 Hz
Noticable moving artifacts on the dead enemies (seems normal on Windows for me)
Occasional FPS drops in reflection-heavy areas
Disabling reflections will have a massive impact on the graphics, but otherwise it is great out of the box with only one tinkering

Screen Refresh set to 50 Hz as game cannot maintain 60 FPS
Drops to 33-35 FPS in wide areas with reflective surfaces.
Frame drops in certain areas, the game is perfectly playable from start to end and the pixel style suits the deck very well.

Game runs really well, turning off reflections keeps a stable 60 but does have an impact on graphics.

TDP 9W
The game might freeze if your system's uptime is too long (if you haven't restarted your deck in a while and instead use Sleep). To fix simply Restart the Deck.
in addition to what is said in the other reports, its a flawless experience unless you almost exclusively use Sleep and never shut your deck down.

Also played on my pc, perfectly playable on both systems
Worked flawlessly, only issue are the achievements unlocking once you exit the game, prompting possibly multiple unlocked achievements in the same session, having the exact time unlocked at once
Changed TDP to 8 watts and GPU frequency to 1000. Left screen at 60hz.
With the power settings I selected I got through the second half of this game with zero issues. Was able to get between 2 1/2 to 3 hours on maxed out settings, so you can definitely do better if you lower settings and refresh rate.
Turn off reflections, TDP limit 10w
Reflections are very GPU heavy in some rooms, framerate takes a hit (down to 40-50fps) the fan ramps up and battery life is rather poor. Turning reflections off solves everything, FPS are stable at 60, battery life jumps from 2-2h30 to 3h15-3h30 indicated. Volumetric effects are less heavy and play a great role in the game's atmosphere, so I kept this setting on, but I guess you can gain even more battery life from turning it off too.
That game would definitely benefit from a screen with better contrast ratio, the blacks are quite washed out. An OLED option would be great. Putting that aside, it's still a great experience on the Deck.
I was surprised that a game with such simple graphics would have slight frame drops in one section. It only dropped to about 30fps during a first person view cutscene, but the rest of the game ran smoothly at 60fps. I suspect that since the graphics are so simple, the did not optimize very well.
Really good experience on Deck. In fact, with the pixelated style, I feel like it's better on a small screen like this than it would be on a large desktop display.
The game runs perfectly on my deck without any tweaks and I'm easily able to get two and a half hours of battery life while playing with medium brightness.
I've played docked on a TV at a 1080p resolution. I didn't notice any slowdowns or unusual graphical glitches, etc., everything worked perfectly. So if you only have a Deck for gaming and wanted to play this game, you're in luck!

Using Humble's app version - Game cannot sustain 60 FPS in all areas maxed out, have to either turn off reflections or volumetric effects.
Runs almost perfectly with 60fps on the steam deck, besides a few rooms with many enemies which drop down to 30-40
45 FPS Sync, SMT off, 2 GHz CPU Clock
Some rooms with many enemies drop performance to 30-40 FPS, othwise works fine
40 Hz / 40 fps
