Unable to launch due to directx error
Tried many version of proton as well as command line args: PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
Launching the game via Steam I'm unable to get to main menu due to a directx crash. Tried lots of versions of protons and many different command line args listed in other people's working reports here on protondb

Better than playing on Windows 11
It was easy to find a server and start playing after a couple server mods had been downloaded.
I haven't tried single-player yet. I'm just excited multiplayer seems to work well.

Proton Experimental
Server list wouldn't load at all for me, even after 10 minutes, while having internet connection
If you would like to play SP, it'll work fine on the Deck, you'll have to be on a PC for MP

Runs perfectly without framedrops (locked 175 FPS on my PC)
German players should use the CompiWare Uncut Patch, it can be installed with Wine, but you have to select the game directory manually in the installer.
Ultrawide also works perfectly, just edit the EXE file with ImHex and replace the value listed on the game's WSGF page.
gamemoderun DXVK_ASYNC=1
Tried multiplayer on 1 server, it works fine.
This is probably the best COD2 experience I had so far. I completed this game very well over 6-7 times, but the experience I had on linux was the best.
DXVK_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 gamemoderun %command%
Without the launch options the game will freeze when exiting a cutscene.
DXVK_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 gamemoderun %command%
During the storming of Normandy, the trench dirt is missing and transparent, but still solid to walk on
I also had to use the previous contributor's launch options for one reason, but wasn't the issue they listed though.
Left click for trackpad; made a custom layout for my Steam Controller when that came out
Captions and objectives
As previous contributor noted, turning and walking at the same time does simulate minor twitching from player character.
First time boot up popped up keyboard (probably for CD key,) but disabled itself
The one modded lobby I joined downloaded files just fine, but after a couple seconds of joining, the game crashed.
Not supported
DXVK_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 gamemoderun %command%
The game dont start without Launch options. You will only have black screen after intros. Launch options: DXVK_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 gamemoderun %command%
R1 to G L1 to 1, B to C key, R3 to Ctrl, L4 to Q (lean), R4 to E (lean), Left trackpad changed to numbers needed for weapons.
Capped at 60fps
If you play more about one hour in one seating the game beggins to stutter really badly. Only soution is to restart the whole game. I dont consider this a major issue, since the checkpoint system is really great, so you will not loose more that 5 minutes of progress.
The "tinkering" is really easy and everyone can do it in seconds. Its only copying few commands to Launch Options and you only need to do it once.

DXVK_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 gamemoderun %command%
If DXVK_FRAME_RATE was used, the mouse movements became choppy while playing the game. If a frame rate cape is needed, use the console or change the config file (seta com_maxfps). See the pcgamingwiki page for more information.
Futher more, when trying to use Mangohud, my game instantly crashed on mission start-up. Disabling/not using Mangohud solved this problem ofcourse.

moving the player and the camera at the same time makes the aiming stuttery
I tried the Multiplayer, and it just runs perfectly, better than I've ever remembered on Windows. Absolutely recommended

Ran well with Proton 5.13-6 and the following launch options:
MESA_GL_VERSION_OVERRIDE=4.5 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
While there was some visual stuttering and slowness, it's most likely that that was due entirely to computer weakness
runs great with disabled fsync and esync. mouse might be impacted by your OS mouse settings
very rarely a small stutter on first startups

Game did not start with two screens. Turning one off, resolved the problem.

To eliminate the micro stutters you have to move the game prefix to the SSD hard drive
Use these launch parameters to get the game working: PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
Spiel stürzt bei 1 Video direkt ab
Just add this launch option> PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
The game freezes at Activision logo without them. Add this launch option:
PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
Unable to skip cinematics without a crash, unable to start a mission

Singleplayer works, Multiplayer only shows a black screen after downloading needed files needed for the game
Multiplayer mode is not working at all

PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
and all is good
Works perfect after adding launch options - PROTON_NO_ESYNC=1 %command%

As long as you don't expect any multiplayer you will have a enjoyable experiance

Only multiplayer tested, runs perfectly.

No tweaks; games runs perfect. Multiplayer is buggy
Game runs just fine for solo play. No noticeable difference from windows. Multiplayer is buggy. In MP, game locked on a frozen logo if I tried to skip splash screens. Was able to force close game by ctrl+alt+del and then right clicking on game icon in taskbar and selecting close game. Alt+tab would not allow that. Managed to get past that on one attempt and get to the MP menu and selected a server. Game downloaded resources from server, then locked on a black screen. Had to hard reset PC. Testing stopped. Maybe someone can figure it out.

Without this flags, first mission of the game does not start and game stuck at black screen.
Set wine prefix's windows version to "winxp" (not sure if it makes any difference. might not be necessary)
- NOT tried multiplayer
- Played the whole campaign at highest possible graphics settings.
Works fine.
The game works all videos and intros on Proton 5.0.5 but it was freezes to start some campaings, i've solved if for now, at least i have few tests but it works. How: change the Compatibility tool to Steam Linux Runtime and the game does a update; change to Proton 4.1 and the game does anothes update; change to Proton 4.2 and the game does different small update. Back to Proton 5.0.5 and everything is working Gold...

Change the Steam Compatibility Tool to Steam Linux Runtime and the game update.
game freeze on some new loadings missions
Played campaign, worked well

Didn't encounter any issue on my side; I haven't tested the multiplayer though.

I submitted a year ago for this game. I gave it a Silver then, but Gold now. The game has improved slightly since then. It no longer seems to crash at random during loading. You must disable Esync, else you will just get a black screen after the main menu. Game runs perfect on highest settings. For a start, cut scenes were just black screens with audio, but for some reason they have come back after a game restart.
