Doesn't start

Does it run better than Windows ? I'm not sure I don't run this shitty spyware OS anymore and that game is awesome to play !
Excellent, looks like it's native.

Crashes too frequently
After the first mission the game frequently crashes after a few minutes, to the point of being unplayable.
Flawless

Works out the box. Suggest bumping most settings to medium, keep textures high and use the TAA upscaling. Fun stuff
Gyro & back buttons makes the game way more playable! Highly reccomend.

Black Screen on start
Black screen on start no matter what version of proton I use. No audio, just black.

Works perfectly out of the box
Performance is excellent as well.

Perfect
Played the whole game + DLC missions without any issue. Highly recommended if you played F.E.A.R and like it (its basically F.E.A.R 2)
Game works prefectly out of the box.
Works perfectly fine
Completed without issues

There is nothing to say, it works perfectly

Haven't noticed any problems with performance

Game runs flawlessly like it was native for linux, only played the first level, but absolutely no bugs so far. Highly recommended.
rare

Didn't even try standard proton, I always use experimental.

Would not recommend on Deck, too much compromise is required to make the game play well.
Set to high graphics by default which results in the game dropping to the 30s and even below fairly frequently. You can set the game to low to achieve 50fps most of the time but then the image quality is horrible, the game looks super flat due to a lack of shadows, and some objective-important objects are straight up invisible. You can turn the AA to TAA, set AA quality to high, and enable TAA upscaling to make the image quality at least presentable but other issues remain. Medium settings with high AA quality is a decent compromise but you'll have to drop to ~40fps to get a stable framerate which results in noticeably increased input lag and that's pretty annoying in a fast-paced game like this. There's really no solid option, no matter what you do the game is either gonna look sub-par or play sub-par.
How this got Verified is beyond me. I cannot imagine anyone playing more than 3 minutes of the game and deciding that "This game's default graphics configuration performs well on Steam Deck." is an accurate description in the slightest.

Installed on Bazzite via Heroic Games Launcher (GOG Version). Runs perfectly, both on the AMD MiniPC and Steam Deck LCD.
Launches to black screen and freezes
No tinkering needed

Semi-frequent crashing. Definitely frustrating, but not too bad with the generous saves

With the game's gamepad support, auto-aim, and gyro, (and the shotgun), this is the closest I have been to using my Steam Deck as a main device for a first person shooter. Unfortunately, I still need mah mouse to headshot, which this game seems to require at times.
Works perfectly out-of-the-box.
Works great out of the box.
Worked fine out of the box. Game runs well and is a blast.

One of the best experinces for a new game out of the box you can have
been playing for a few hours, no tinkering needed on stock ubuntu 22 with nvidia 510 drivers.

Fantastic out of the box experience. Played the entire game, secondary missions included and a couple of horde mode maps with no issues.
Game displayed an error message saying "Fatal Error!" a fe seconds after closing the game. Happened to me twice
Some information about my setup: I am running Gnome 45.2, on an Nvidia laptop, with the entire xorg session being rendered using the Nvidia card. I also have my laptop hooked up to a second external monitor.

FYI, The demo had some issues with stuttering the full game however doesn't experience this in the slightest.

PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command%
Game runs like a dream. Super smooth and zero issues.

PROTON_ENABLE_NVAPI=1 %command%
Had some minor latency/tearing issues before using the launch parameters as shown. Felt much more responsive after adding those.

It ran like 2x better than it did on Windows
I ran it on Ultra Settings and it ran at a perfect 60

It's a mix of F.E.A.R. 1 and Crysis 2, combat is visceral, and hectic.
I had some issues getitng it to work, kept demanding D3D12Core.dll, but then suddenly started working, proceeded to work flawlessly. Was able to effectively play the entire game front to back.
