works so long as you don't alt-tab
alt-tabbing or minimizing the game makes it go to a black screen. Have to restart game to play it again

I needed to lower the graphics settings, but this is probably caused by running it on external monitor with 1920x1080 resolution, so not an issue with Steam Deck

LD_PRELOAD="" DXVK_ASYNC=1 DXVK_FRAME_RATE=60 mangohud gamemoderun taskset -c 0-3 %command%
Without LD_PRELOAD=""
the game would start stuttering with every pixel that mouse pointer was moved and alt-tabbing could occasionally result in a black screen.
The other launch options listed I got from the other reports here, but the stutter and black screen were the only issues I discovered personally.

I played a bit of this on Manjaro with proton 9.0 and am currently playing it on CachyOS with their custom stuff. Works great on both.
Headache-inducing stuttering
Stuttering bad enough it makes the game unplayable
Stuttering bad enough it makes the game unplayable
No idea if the game suffers from the same issues on Windows, but it's unplayable for me as of now. Stuttering is associated with neither particularly large GPU nor CPU load and occurs even if limiting the game to 4 cores using taskset -c 0-3 %command%
, and is associated/noticeable with camera movement.

mangohud gamemoderun %command%
works OOTB
Worked well out of the box including mod support via UMM loaded via lutris

The game demands a lot from the hardware, my GPU often couldn't handle the demand. I have to lower the quality of the shadows.
DXVK_ASYNC=1 DXVK_FRAME_RATE=60 gamemoderun taskset -c 0-3 %command%
The game has a tendency to have slowdowns due to not knowing how to match the FPS to the monitor frequency.
The game has a disproportionate demand on both the CPU and GPU. Hence the taskset command and the fps limitation command.
Sometimes the command in the game, such as attack and go to a certain point, is not detected.
Limit the FPS, lower the shadow quality, limit the number of CPUs the game will use -- because it seems like the game was made for CPUs with few cores.
One crash which prevented me from progressing in the game. I had to set PROTON_USE_WINED3D=1 in order to skip the crash.
Working better than on Windows lol. Perfect, native-like experience.
Works great

Works just like on Windows for me, due to cloudsaves, switching was very easy
Occasional freezes with Proton Experimental, works with 8.0-5

Having a high rate of repeat keys in settings causes lag when moving camera with keyboard.
Rotating Camera Feels Clunky
Over 300 hours played, finished the game, no issues

Excellent on default 8.0-3 or Experimental except for shutdown issue (below)
Doesn't shutdown properly; Fix: Turn off "lockMouseToWindow" in-game setting, then you can shut it down using the mouse to click STOP in Steam.
Does not shutdown properly; Fix: Turn off "lock mouse to window" in-game setting, then you can turn it off each time after quitting by clicking STOP in Steam.

Can not proceed in story after few hours
Gwern Mansion bug is present
Can not proceed because game crashes SDDM, but not not itself when entering Gwerm Mansion location. SDDM restarts but game process is hanged, can not be killed and game music plays

Runs great, no tinkering needed
Never experienced the black screen bug some other people report despite alt-tabbing generously. If you want to use mods, use WINEDLLOVERRIDES='winhttp.dll=n,b' %command%
as a launch argument, otherwise the winhttp.dll installed by Unity Mod Manager won't work and mods won't be loaded.

DXVK_ASYNC=1 gamemoderun %command%
Newest version GE-Proton8-6 fixes the long standing issue of unfocusing the window, causing the screen to be black and needing a restart of the game. This now works perfectly and switchting focus does not cause the screen to be black anymore.
Proto
Generally fullscreen or borderless mode (because the game doesn't have a real borderless mode) causes the game to minimize. This unfortunately causes the game to become unreponsive. Putting it into exclusive mode seems to allow for a singe click outside of the window, but further will cause the previous issue. Putting the game into windowed mode is seemingly the best option to avoid this, even if its temporary.
Modding can work but i did need to jump through a few hoops to get the unity mod manager to behave as you need to point it to the correct directory.
Setting up the modfinder tool isn't too bad as long as you setup protontricks with .net; and it makes automated setup and limited wine/mono/prontontricks utilization and messing around with zip files easier.
Works perfectly after install. No tinkering needed for this one!
Display server: X11 - Proton version: 7.0-6.

Works right out of the box
Gameplay is smooth and looks great. While I did experience rare freezes during load screens that was a long time ago now
Works perfectly out of the box!
No issues found
Works just fine
The game really doesn't like alt-tabbing. Irregardless of whether the game is in borderless or exclusive fullscreen, alt-tabbing causes it to no longer respond.
Some controller models seem to give ghostly stick drifting that is not present in other games
No lagging, mods also function correctly
Changed some controls around
CPU 8W and GPU 1200Mhz
Sometimes text is a bit small
Sometimes crackling sound
Very limited crackling on rare occasions
Game is buggy in general such as UI doesn't work sometimes. Unrelated to Steam Deck
Some text is small in the city building minigame. It's just large enough to be readable at native resolution. If you reduce the resolution and use FSR, it's illegible.
There are some small number of videos at the start for tutorials and one prerendered movie that don't play correctly on the official Proton. Using GE-Proton solves this.
If the game is running in full screen, the mouse cursor will be trapped by it even if siwtching workspace.
The game work flawlessly from the beginning to the very end.
Install Steam… Enable 'Proton experimental' … Install and Launch the Game … Have fun 8)
Wouldn't open at first. Just had to get the latest nvidia drivers, and now running smoothly.
play runs out of the box fine for me, no problems, native controller support, only thing is that it does suck the battery suprisingly heavy
40fps cap

Generally playable but has slowdown. This is usually fine in turn-based mode but results in some jitter when walking around. Didn't seem to resolve regardless of settings used.
It's tolerable but doesn't perform as well as I'd have hoped on Deck. Otherwise works as expected.
