I could not Alt+Tab during Fake Fullscreen. The task switcher pops up, but it could not bring selected windows forward. I had to set Fake Fullscreen and then force fullscreen in window rules.

Works out of the box!
Proton 9.0-4
--skip-launcher

Most of the text is pretty small and can be hard to read. Diologue boxes and diologue choice text is small.
Works great with the default Proton 9.0-4 as of 2/23/25. No tinkering needed!
env -u SDL_VIDEODRIVER %command% --skip-launcher

It works without configuration and do not use gamemode it makes the game crash on startup
LD_PRELOAD="" mangohud %command%
[LD_PRELOAD=""] is for slowdown issues after 30 min (I do not know if the game have it, it's there just in case)

PROTON_USE_WINED3D=1 %command% --skip-launcher
Some textures do not load and are replaced with white boxes.
Game does not launch at all with default proton. Runs in Proton-GE but is not a good experience due to missing textures: chunks of the UI is missing, in-game letter was unreadable. Gave up part way through the tutorial.

Completely unplayable
Clicking "PLAY" in Steam does nothing. No launcher, no game, completely broken and unplayable on default proton, proton experimental and latest proton ge.
Works ootb on wayland but you have to unset SDL_VIDEODRIVER variable or it will crash on start with DXGI_ERROR_INVALID_CALL.
env -u SDL_VIDEODRIVER %command% --skip-launcher

Without "PROTON_USE_WINED3D=1 %command%" the surfaces are invisible making the game difficult and irritating to play.
PROTON_USE_WINED3D=1 %command% --skip-launcher
Using PROTON_USE_WINED3D=1 %command% fixed graphical issues but lowered performance by about 10%

With invisible terrain surfaces which are a major part of tactics and the series flagship feature i just can't recommend playing it.
--skip-launcher
Surfaces (water,blood,fire, and poison) don't render at all, making the game extremely irritating to play
The problem is not with OpenSUSE, the game works identically on EndeavourOS

Can be fixed by mod
Game does not close properly no matter which proton version i use (GE, experimental or latest)

I played a full campaign with my friend, no issues at all.
Works OOTB

just works
--skip-launcher
Игра шла идеально и пройдена полностью. Никаких глюков не было, раза три выбила, но за более чем 60 часов игры это ни капли не расстроило.

--skip-launcher
Ocassional crashes on experimental. Switched to Proton GE, none so far.

Game working perfectly on steam deck
--skip-launcher

--skip-launcher
No issues with single player. Didn't try multiplayer.

Works Out of the Box


Cannot get game to launch
The launcher works fine, but the game itself fails to start due to DirectX failing to initialize. I tried all sorts of fixes suggested, but none of them worked for me.
--skip-launcher

All simple workarounds did not work. Tried multiple versions of Proton and multiple launch params.
Not worth the time tinkering

Works great, no extra steps!
Multiplayer works flawlessly.
Really great Linux playing experience with this game.

WINEDLLOVERRIDES="DXGI.dll=n,b" PROTON_NO_ESYNC=1 %command% --skip-launcher
added DXGI.dll script extender for DOS2
Did a full playthrough with no issues, however I had to use Proton 7.06. To load the script extender you have to disable esync

prime-run gamemoderun %command%
/usr/local/bin/prime-run:
#!/bin/bash
export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __VK_LAYER_NV_optimus=NVIDIA_only
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json
exec "$@"
I would recommend adding prime-run, it fixed a recurring issue with games not utilizing my GPU.
cannot start playing because of crashes always crashes randomly after like 2 min. tried protonGE. same crash.

Works great and runs really well even with mods but have to make one change for the GOG Version
Multiplayer worked perfectly, even modded. Worked with over 50 mods
To make it work on the GOG and Steam version, find the EoCApp.exe and launch from that. For example, the GOG Version's path for it is: "user/Games/divinity-original-sin-2-definitive-edition/drive_c/GOG Games/Divinity - Original Sin 2/DefEd/bin/EoCApp.exe". You can probably find the same path in your Steam installs folder. Make SURE to launch it from the EoCApp.exe so that it skips the launcher
Keep in mind the DefEd folder, that is where you will be installing your mod loader and what files to tinker with.

holding center click would act like it was on the desktop.
Multiplayer worked perfect, tried with a windows user while on linux, no issues with connectivity.
outside the mouse issue it runs rather well,this could also be a user error, im launching on a fresh install of mint with latest drivers installed.

Works great out of the box
Did a full (single player) playthrough without any issues whatsoever

eval $( echo "%command%" | sed "s/bin\/SupportTool.exe'.*/DefEd\/bin\/EoCApp.exe'/" )
Skipping the launcher as seen in other posts no longer works, you will experience a dotnet core related error, without any form of hope even if you install this exact version it wants into the wine prefix. You must add this new launch option to bypass Larians new launcher.

eval $( echo "%command%" | sed "s/bin/SupportTool.exe'.*/DefEd/bin/EoCApp.exe'/" )
This game used to work with a skip launcher launch option, there seems to have been a ghost patch that broke things. launching it with this new flag bypasses the new dotnet bug.
