DXVK_FRAME_RATE=75 %command%
Frametimes are awful, feels very choppy even at framerate cap limit

the game did play without any tinkering but it worked alot better with Proton Experimental (ROG ALLY Z1E)
Clicked play and it works! Great performance
runs like crap at 4K but thats probably just the game

Basically ran out of the box
Only problem was a small amount of frame drops in the first 5 minutes of the game, else it worked flawlessly

%command% -dx11
Just a couple of notes:
Adding
-dx11
was necessary, otherwise even the first screen (Unreal Engine) would fade in five seconds per frame.Current Proton 9.0-4 / Hotfix / Experimental renders the Buck Thunder 2 intro at a couple of seconds per frame, even on DX11. Overriding version to Proton 8.0 works perfectly.

doesnt work
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia PROTON_LOG=1 %command%
doesnt work at all I tried everything others said but couldn't play, maybe about my distro

Unplayable: without "%command% -dx11" the game won't open, and with these parameters, the game launches and runs with low fps (5 or less)
%command% -dx11
Unplayable for now, and it's the same with standard Proton, GE-Proton and Proton Hotfix

Doesn't launch at all
gamemoderun %command% -dx11
"DX12 is not supported by your gpu", adding -dx11 ---> "a D3D11 compatible GPU is required to run the engine".
PROTON_USE_WINED3D11=1 remove the error but the game doesn't start. Proton Ex, GE-Proton9, Proton 9, 8,7,6 nothing is working. :sad:

Changed the keyboard & mouse controls ro match the controller layout, while leaving the gyro active when touching the right trackpad or right stick.
The fps fluctuates between 40 and 60 even on the lowest settings, if left uncapped.
The game is definitely fun to play and I had a great time going through the missions and listening the gatlians speak, but the performance is not that great for me.
Since I got the deck, I stayed away from shooters, because I know I am terrible at hitting the targets with a controller. However, since the deck has a gyro I wanted to learn how to use it so that I can play shooters on it. The first thing you have to know, is that the game doesn't support multi-inputs, so you can either use the gyro as a joystick/joystick camera or bind every button from keyboard & mouse to the deck's buttons. I started with the first option, but the experience wasn't that great, because there was a significant lag that I couldn't bear. So then I tried the second option. After a lot of tinkering, looking at some tutorials and reading some blog posts, I got to a point where the gyro was usable.
However, due to the bad performance of the deck (or maybe the game? I heard that the game isn't optimized even on higher end pc configurations), it gaved me mixed feelings. In the rare occasions where the game did run at 55-60 fps, the controls felt good and I could start getting accustomed to the gyro. However, most of the time the game's fps spiked from 40 to 60 even on the lowest settings. I even tried to turn on the Allow tearing in the deck's settings in order to reduce the input lag that I felt (it may be different for you and I'll explain why in a second), but due to the low fps, I just couldn't enjoy the game fully.
That being said, if you can play shooters locked at 40 or even 30 fps, then you will definitely have a blast with this one. I, however, can't. I started with a locked 40 with no gyro, then after a mission or so, turned on the gyro, but eventually I uncapped the fps because my eyes couldn't stand the fast action at that fps level.
If you are like me, then you'll have to play on story mode or at most normal mode difficulty level (I beat the whole game on normal mode, with the exception that for the last boss I switched to story mode because I just wanted it to end), if you really want to take a shot at this on the deck.
Nonetheless, here are the settings that I've used:
- Motion Blur: Disabled
- Texture Quality: High
- Upscaling Technologies: Intel XeSS
- Upscaling Mode: Balanced
- everything else set to Low
And I've also activated the Allow Tearing option in the steam deck's settings.
No issues

Performance was great, ran wonderfully and played from start to finish
Very rarely a character model would go missing, probably a bug in the game itself. Final boss vanished between phases, using "last checkpoint" fixed the problem with no lost progress
Works perfectly fine.
Runs perfect with NVIDIA DLSS on.

Beat the main game and DLC, 0 issues
Good game, had no issues.

Except for one crash (PC completely restarted) the game runs flawlessly. When moving fast some ghosting appear in the edge of the gatlings
Ghosting on the edges of the weapon when moving fast, barely visible
Crashed once in 10 hours

Had to switch to windowed mode in order to change resolution to 3440x1440. If I enable AMD FSR 2.0 or Intel XeSS the game will constantly crash with a DX3D error every 10 minutes or so. Disabling these settings makes the game very stable. Have played for about 5 hours now and haven't had a crash since disabling FSR.

Crashes after first splash screen
WINE_CPU_TOPOLOGY=16:0-7,16-23 DXVK_HUD=compiler %command% -dx11
Tried several tinkering options and different Proton versions, and -dx11. Longest I could get was to see the Squanch Games splash screen (with lag), and the game goes black

Works well, some graphics glitches
Mouse is sluggish in the menu

Чудово грається на Стім Деці зі стандартним Протоном, технологіями масштабування графіки та низькими налаштуваннями.
Зменшено TDP до 10 у маленьких картах, 11-12 у великих місцях.
FPS падає в деяких моментах гри, але не дуже часто. В залежності від графічних налаштувань, падіння може бути суттєвим.
Гра повністю підтримує геймпади, на Стім Деці не було проблем із запуском та грою. Якщо скрутити налаштування в мінімальну якість графіки та використовувати технології масштабування, то можна отримати 55-60 FPS в більшості ігрового часу навіть при використанні зовнішнього монітора. При цьому, треба обов'язково поставити середню або високу якість згладжування. AMD FSR 2.0 Balanced дає більший приріст FPS, але якість зображення страждає трошки більше. Intel XeSS Balanced дає кращу якість, коштом трошки меншої продуктивності. Очікувана тривалість гри від батареї на таких налаштуваннях: 2 години 10 хвилин, при 12 TDP.

the game runs smoothly and I have no/few problems with high on life or proton and steam in general
WINE_CPU_TOPOLOGY=16:0-7,16-23 DXVK_HUD=compiler %command% -dx11
sometimes low fps but after reboot it was fixed
I can only recommend it
WINE_CPU_TOPOLOGY=16:0-7,16-23 DXVK_HUD=compiler mangohud %command% -dx11

-dx11
Game and steam both crash (with max cpu usage for 5 seconds). Error is caused by a bug in the DX12 launch and results in some of the intro splash screens not playing and a hard crash during the loading rocket animation.
Great game and works perfectly on Linux!

Finished game with no real issues
Occasional slowdowns

The game started, I was able to play it for 7 minutes, and then it crashed. and it never ran after that. nothing I could do would fix it.
Runs pretty well, no crashes. Some FPS drops but that's probably just the game, not Proton.

works well with proton 8.0.2. the game doesn't lauch with nvidia driver 535 but no problems with the 525 (linux mint)
gamemoderun %command%

Installed and hit play, worked with no special changes
Smooth and clean, no issues.
Lowered framerate to 40 to get more out of the battery, but plays perfectly at 60 FPS if you're not as bothered by battery life

PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command%
It was hard to get it to fit my 3440x1440. Used windowed mode in lower resolution, dragged it to that monitor and then switched it to "Windowed Fullscreen".
No custom command lines are necessary, but the ones I've pasted enable DLSS and probably more native Nvidia features for those with Nvidia RTXs.
Here is how I was able to get the best image quality locked at 30fps:
Deck: 60hz, Framerate limit set to 30
Game: VSYNC off, Chromatic Aberration off, Overall High Settings, Shadows set to medium and Foliage Quality set to low. Rendering resolution set to 50%.
To make the 50% rendering resolution look good, we will enable TSR in the unreal engine by manually editing the engine.ini file located here:
/home/deck/.steam/steam/steamapps/compatdata/1583230/pfx/drive_c/users/steamuser/AppData/Local/Oregon/Saved/Config/WindowsNoEditor/engine.ini
- And add the following lines at the bottom of the file to activate TSR:
[SystemSettings]
r.DefaultFeature.AntiAliasing=2
r.PostProcessAAQuality=4
r.TemporalAA.Upsampling=1
r.TemporalAA.Algorithm=1
r.ScreenPercentage=50
Worked like a charm
The game runs flawlessly without any additional configuration
Runs good OOTB.
Some occasional stutters
