PROTON_USE_WINED3D=1 PROTON_ENABLE_NVAPI=1 %command% -novid

Runs well out of the box
audio is sometimes slightly choppy or ends too soon
Weird shadow artifacts around certain objects and in certain scenes - might just be a bug in the game itself, I haven't played this on Windows, so I can't compare
It has some flaws, but that might just be bugs in the game in general and not just the Linux version.

Gotta Love Native Games
My Game Crashed Twice I think
Besides 2 crashes It ran great! Not sure why it crashed but I also stream and use Hyprland so who knows if it was the game or something else.

gamemoderun %command% -nojoy -nosteamcontroller -novid -vulkan
I don't recommend using "fps_max 0" as it may break the game engine, but if you are planning to play with it, use -vulkan to not hit the 99% mark of your GPU or if you prefer the stability of vulkan.
-vulkan
Smooth ride

Perfect
Works without issue. Great game!
It's probably the worst of the three but still good

ENABLE_VKBASALT gamemoderun %command% -vulkan
Use vkbasalt and reshade for an even better experience

Runs perfectly
I wasn't able to adjust gamma.
obs-gamecapture gamemoderun %command% -vulkan

%command% -novid -vulkan +fps_max 61
Using proton, the cursor goes slow. It is solved by activating the game option: Settings->Mouse->Direct input
Running the game on its linux version, the cursor would suddenly slow down. It was fixed by restarting the game. It doesn't happen with proton.
Using the command "+fps_max 61" limits the fps and the stuttering disappears almost completely.
Proton 5.0 seems to be running more smoothly than the most current versions

-vulkan
Очень редко и в определенных местах появляется квадратная тень от Аликс
Lots of microstutters but does not greatly affect gameplay
problem seems to come to the Source engine itself (or rather, it's compatibility with my drivers or card), as the same issue popped up in Black Mesa, Snowdrop Escape, HL2 and HL2 ep2.
I've changed some keymappings for my liking, this game support Steam Input mapping which makes things very easy
Set the CPU to 5W
Runs perfectly fine, set the CPU to 5W and the graphics to High without AA. Start to finish with a single charge and still left 35% of battery remaining. This games is adapted to the Steam Deck so input and substitles are easy to read and work perfectly fine
I only ever had 1 crash.
Runs good besides one issue
Steam cloud sync must be enabled or your saves will be deleted when you quit the game.
Trying to use "Windowed (No Border)" Crashes the game
Mouse was not captured, so it stopped at the edges of the display, had to use raw capture
Running perfectly through Proton, there's a native port too but didn't work for me.


Game works native on Linux. On Proton the game works too out of the box, only if you click on options the game crashes, but I changed the resolution with the parameter -w 3840 -h 2160. I installed manually D9VK and it worked without graphical glitches too with this DX9 to Vulkan translation!
