The game works perfectly but if the parameter is not specified, it does not start the game.

The game works perfectly but if the parameter is not pointed out, it does not load the map at all, for some reason this game is incompatible with Directx 12 and I could only make it work on the heroic game launcher, on steam it always gave the error "steam offline" even when online, it seems that proton on steam has problems communicating with the steam launcher, at least on my computer,
It runs out of box.

gamemoderun %command%
DELETE RESHADE IF U HAVE IT!
mangohud %command%

gamemoderun %command%
Changed to borderless fullscreen to fix
Didnt use mangohud as the game wouldnt launch
Installing EasyEffects made dbd start crackling randomly, fixed by running
pw-metadata -n settings 0 clock.force-rate 48000 && pw-metadata -n settings 0 clock.force-quantum 500
every update (and the ptb) worked, now nothing works didnt go any further than the anticheat/easycheat pop up

PROTON_ENABLE_WAYLAND=1 %command%
Just need to use GE-Proton10-4 and add PROTON_ENABLE_WAYLAND=1%command% as a launch option
Game ran great without tinkering on the latest stable Steam version of Proton. Very nice experience.

Worked amazing, proton hotfix
:)
It runs just as well as on windows. Has some slight freezes here and there, but it's the exact experience I had on WIndows.
gamemoderun mangohud %command%

FPS drops.
About 5 minutes into the match, based upon some sort of foilage density, I experience major FPS drops on Experimental.
On larger, wide open maps, typical with dense foliage, I will experience major frame drops on Proton Experimental. At present I've dropped graphics settings to low while maintaining 100% resolution scale. I have also disabled TAA.
Combined with graphics settings -- I switched to Proton 9.0-4. Thus far I've not see the 10fps / large frame rate drops as before.
Again, this only seems to appear when there's dense foliage or weird particle effects.

The game is really buggy since last updates, i've already tried many launch option and reinstall my graphic drivers unsuccessfully
PROTON_LOG=1 ENABLE_VKBASALT=1 %command% -dx11
if i put an headset while the game is already running the game is going to crash
if my cursor is not on main screen the game crash before arriving the main menu
Many in game and often on the main title

If playing for prolonged period of time, may cause lag but not all the time.
Proton 9.0-4 did not allow me to open steam overlay so I switched to another version, experimental and the beta version works fine with the steam overlay. Besides that everything is flawless and a pleasure to play this game on Linux.

I couldn't alt tab out of fullscreen without the Launch options. This: WINEDLLOVERRIDES="d3dcompiler_47=n;dxgi=n,b" %command% -dx11fixed it for me
Game runs well with no issues.

LD_PRELOAD=/usr/lib/libgamemode.so ENABLE_VKBASALT=1 gamemoderun mangohud %command%
Occasional freezups while playing, This can happen in menus or in game. Fixed by double pressing the meta key to pull up another window
For the most part it runs great right out of the box, aside from a few freezups that might happen once or twice a day

Game sometimes crashes on startup
If you want Reshade shaders be ready to switch to VkBasalt as Reshade is bugged for this game.

Works well out of the box.
I would tweak some of the settings to make it more enjoyble for your average Joe.

Installed ReShade through steamtinkerlaunch
Game used to not work due to ReShade (after a recent update ) but after reinstalling DBD and using GE-Proton10-1 it works perfectly fine now

mangohud %command%
Do not use Reshade after the update because the game won't launch.
gamemoderun mangohud %command% -dx11

Game used to work perfectly fine, after update it crashes on startup. Nothing fixes it
Hope it gets fixed soon so I can play the game again
mangohud gamemoderun %command%
Worked perfectly fine OOTB at 120fps very stable, but I decided to use ProtonGE anyway. Still stable and works perfectly.
gamemoderun %command%

The game still very playable it's when you have very extend play session it start to lag for me ( 4 - 5 hours )
-d11
When i play for long time i have some little lag but it's minor
No problem for mutiplayer work perfectly
he can take pleasure but parameter is still recomended for less lag

The game runs out of the box
No need for changes, just install and play. Works normal and no problem changing screens on EndeavourOS

WINEDLLOVERRIDES="d3dcompiler_47=n;dxgi=n,b" %command%
As of last update alt tabbing occasionally fully bricks the game, requiring a full game restart to be playable again. Did not happen prior to update
See above
Worked ootb. Hopefully this issue gets patched or its some kind of poorly timed user error on my end. Steam launch command is for reshade

%command% -DX11 -USEALLAVALAIBLECORES
Had to switch to proton experimental (instead of the default 9.0-4) with the latest update (DBD 8.7.0), I was otherwise stuck before the main menu loading screen with a connection error reported by the game. Maybe other proton versions work as well, experimental is just the first one I tried

Game works completely fine
No way to even tell that it isn't running on Windows.
