Played multiplayer from start to current content without any issues at all. Ran smooth and performance was better compared to when I tried it on Windows. Enjoyed every moment.

If you trying to play with Proton Experimental you may need to install VC Redist and .NET Runtime from protontricks to start the game.

Ironically this works far better on Linux than on Windows
I havent experienced a single crash playing completely normal (non D11), yet my Windows friends on Nvidia GPUs have experienced quite a few crashes.

Works great, as long as you run in DX11 to avoid crashes
Must be run in DX11 mode (prompted by steam at startup) otherwise crashes so frequently it is almost unplayable

almost standard control pad layout but due to a bug remapped RB to the corresponding keyboard key for rotating pieces. Also remapped vehicle controls to keys due to a current bug they have with controller buttons driving vehicles.
limited to 30 fps to save battery
see comments above
In game video settings:
- Resolution scale 65 (very important, no visible difference from 50 to 100 except alot of fps drop. Below 50 then game becomes blurry and it really messes with anti aliasing when looking through chainlink fences. Below 65 then reading ingame computers is impossible and above 65 makes the deck unable to keep a stable 60 fps).
- Vsync OFF.
- Max Fps 60.
- Gamma 1.70 (sets it much darker, improving the atmosphere feeling greatly, you are intended to survive in a game where the time of day and the battery of your flashlight is of utmost importance? To feel alive knowing that death lurks around every corner. Put it lower if you dare.)
- View distance LOW (close quarters game. This stops your game from loading what you cannot see past walls. 10 fps difference up to epic and zero visible difference between low and epic in very very large rooms).
- Post Processing MEDIUM (retro game, no need for more. No visible difference).
- Shadows MEDIUM (no visible difference to epic.)
- Textures HIGH.
- Effects MEDIUM.
- Foliage MEDIUM.
- Global illumination HIGH.
- Reflections HIGH.
- Bloom EPIC.
- Anti Aliasing LOW (Eats fps. No visible difference).
- Anti Aliasing type TSR (anything else gives a smudged mess).
- FOV 95 (need more vision on such a small screen to not get tunnel vision.).
- Subtitle size medium.

__GL_THREADED_OPTIMIZATION=1 WINEDEBUG=-all ASYNC=1
For reference, with my hardware and the game running on lowest graphics playing single player, it averages 80 FPS

As native to Linux as a game can get!
Runs well on Proton Version 9. Just install and play!

👌 👌 👌
It works perfectly without any problems.

Runs great
The game would rapidly flicker outside of fullscreen
With max settings at 1440p, I am easily able to achieve >120fps. The game looks and feels great.

Zero complaints, both in performance and game itself.

protontricks
On my desktop PC it works perfect, on my laptop with a intel cpu and Nvidia GPU it runs into a lot of issues.

Runs perfectly in DX11 without tinkering and runs in DX12 if you run the protontricks line
protontricks 427410 win10 vcrun2022
The protontricks line is necessary for DX12 mode to work.

The cursor did not appear immediately upon dying and required I opened and closed the menu before being able to select a respawn location. No idea if this is related to Proton.
During the intro looking out into the great wilderness caused signifigant slowdown, even when the distance itself wasn't being rendered (indoors). This did not occur throughout the rest of the gameplay (which was inside the facility), and the intro otherwise ran fine.
Game freezes on the first loading screen when launched with DX12. DX11 worked out of the box.

As of the most recent update, only dx11 mode works for me, but everything else is still flawless.
Worked flawlessly, dx12 right out of the box. No issues

Half Life survival with a very likeable cast of characters and cool tech to discover
On the recent update there are some artifacts with the flashlight, but not often
The game runs at medium 60fps but dips hard to 15fps very often
Very fun game, if you need more FPS you can also turn off Lumen in the config files (not in game)

Major inspiration from the HL1 era of gaming, combined with modern survival (horror) elements and humor.
I can run the game in DX12 but on the start menu I had about 10 fps, whereas on DX11 'lower end pc mode' it runs with 200+ fps. So use of that mode is highly recommended.

I used GE-Proton9-10 and tried it with proton experimental and 9.0-2 with no problems aswell
Worked for me under both Wayland and X11
Tryied only single player so far, but works flawlessly.

Couldn't get more than 10-20 fps
Had to run it in DirectX 11 mode even though my computer is not lower-end. Once I did that I got 180-220 fps at epic graphic settings.
No other problems so far.

DX12 hard crashes randomly, DX11 has noticable performace hit compared to DX12. otherwise game runs fine outta the box.
Occasionally while alt-tabbing, the the game will flicker rapidly on top of the window i tab into. though this happens with other games/software i use.
I have to launch through the DX11 option due to DX12 hard crashing randomly. There is a noticable decrease in performance. DX11 will dip to 40-50 FPS in more detailed areas while DX12 hits my FPS cap of 75 almost constantly. (High Settings)
DX12 launch will hard crash whenever it feels like it. DX11 has not crashed for me yet.
Most of my problems revolve around DX12, of course all of this may be different depending on your system yadda yadda, game is good.

The selectable "Play Abiotic Factor (DX11 for Lower-End PCs)"
Occasional client-side failure to see what server user had placed. Possibly just an early access bug and platform agnostic.
It wouldn't launch by default, but given the built in launch option and change to forced experimental fixed the problem it's not much tinkering to do for me. My low-end GPU could very well be the only reason the launch option is necessary.

__GL_THREADED_OPTIMIZATION=1 WINEDEBUG=-all ASYNC=1
Particle effects reduce my PC to ~10 FPS; low options for everything else ~25 FPS (1080p)
It'd really be nice if E.G. the Office Lv3 zap pool spark area were able work at 30FPS with ease; as the first "easy" to get to area that shows how poorly the settings scale down to my hardware.

__GL_THREADED_OPTIMIZATION=1 WINEDEBUG=-all ASYNC=1 PROTON_HIDE_NVIDIA_GPU=0 DXVK_ASYNC=1 PROTON_ENABLE_NVAPI=1 DXVK_FRAME_RATE="144" gamemoderun
Disabled Lumen by adding 2 lines of code to the end of the Engine.ini file to make the game run better and get rid of the annoying global illumination rainbow bug.

Runs smoothly like a Gordon through Black Mesa
Just grab some friends and play!

Went through character creation/tutorial with no issues. Multiplayer works fine too (tested with 5 players total).
First-time players will want to set texture resolution to 50-60 so reading emails on computer consoles will be legible. You could probably get away with lower values depending on your hardware/performance preferences.

Works out of the box
Played for 25 hours as of this writing. It plays just flawlessly.

Always got an "Assertion failed" Error
I've tried Proton Experimental, Proton-GE, Proton 9. I also tried DirectX 11 Version. Nothing works. I always crash with an "Assertion failed" error.

Only worked after forcing experimental, and only then on DX11 mode. But other than that it plays fine with no issues.
Game only launches in DX11 mode. Otherwise crashes on splash screen.

Was able to play for a couple hours hosting a server for windows friends with zero issues. Game runs slightly poorly considering the hardware; However, from reports from friends on windows, this seems to be poor optimization with the game itself unrelated to proton.

Ran perfectly fine, no audio or other glitches. Using proton 9.0
