gamescope -e -f -W 3840 -H 2160 --force-grab-cursor --backend sdl gamemoderun mangohud -- %command%
On Gnome, fullscreen is broken, gamescope fixes the issue of fullscreen but the window doesn't grab the cursor, only adding "--force-grab-cursor" doesn't fix the issue, adding "--backend sdl" seems to fix it. No problem on plasma.

works okay, need to resolve the hitching
Graphics are fine at first, then at a certain point in the session they switch to hitching when rotating.
Mouse bounds are wrong if run on a screen which does not start at x=0. I don't know if this is caused by the game, Proton, xwayland-satellite, or niri (my compositor).

LD_PRELOAD="" %command%
I'd say it runs even better than in Windows. No lag spikes whatsoever

Other than graphical glitch on menu unless you set to Window Fullscreen, works great!
On start up half the screen has black blocky corruption. Changing the game to Window Fullscreen rather than Fullscreen fixed it
I haven't changed any proton settings or anything. Completely out of box it works great! Had to change to Windowed Fullscreen but on ultra settings the game is super smooth. Haven't seen any other issues once in game, super smooth and works great.

It was enjoyable at first despite the freezing/crashes, but it grew to be entirely unplayable and I gave up and went back to Windows
A couple times, fullscreen was not full and resolution detection was incorrect, but this was not consistent
At first, occasional significant (20+ seconds) freezing despite otherwise flawless performance on Ultra. A couple days later, less than 2 FPS on Low for no discernible reason.
As it stands, I simply can't play this game on Linux and have to switch to my Windows boot to play it.

gamemoderun %command% -vulkan
FSR/TSR cause quite noticable aliasing (At least in late game)
Disable FSR/TSR and definitely play on Vulkan for the best performance possible (Either through video settings or simply by adding -vulkan
to your launch command)
Just works

It crashed my whole DE after each autosave.
My game crashed my whole DE, so if you experience the same issue, try switching to Vulkan in the settings. It also improves the FPS drastically with an AMD GPU as an added bonus.

I had problems with performance on windows with this game it would stutter on the highest settings until i lowered them, I tried it on linux and the performance problems were completely gone I can run the game on the highest settings (no raytracing) without any stuttering and as a bonus using linux makes my GPU run colder than on windows

Yes. Suprisingly, the game runs at my monitor's max (165fps) at 4k. In Windows 10/11 I rarely saw it exceed 120fps.
DXVK_ASYNC=1 LD_PRELOAD=”” %command%
Running without the tweaks here, the game would stutter after about 20 minutes. Once the tweaks were applied, the game runs perfectly (Right-click the game in steam, select properties, paste the tweak here into the LAUNCH OPTIONS box).
Note that I am using KDE 6.3 with Wayland and have HDR enabled on a 4K 165hz monitor. I run the game with all graphics settings at max/ultra.
Works great without any modifications!
gamemoderun %command% -vulkan
Game crashes on exit. No adverse effects, besides the minor annoyance of closing an error popup.
-dx12
Sometimes walls don't render when looking at them at some angles
Runs awesomely

Ran with no tinkering or issues. Haven't played long on Linux but didn't face any issues so far.
Game has run perfectly on 500+ hour world
gamemoderun gamescope -H 1440 -f --mangoapp --force-grab-cursor -- %command% -vulkan

VKD3D_FRAME_RATE=80
Works pretty much out of the box on vanilla Proton. Performance wasn't nearly as bad as I feared. I put everything on high or ultra on 3440x1440, set FSR to the Quality preset, and I was able to get a framerate somewhere between 80-100. I ended up settling on capping the FPS at 80 for a more stable experience.
By late game performance had made a significant downturn, but still only dipped below 60fps in the most intense parts of my massive factory.
This is the first game I've ever played that supports AMD's FSR Frame Generation. I tried it out for a bit, but it made my mouse movement feel so sluggish and awkward that I immediately turned it off. For me it was 100% unplayable.
In over 150 hours of playtime, I experience a single hard crash, as well as one network error. I played through most of the game together with my brother, and there were pretty much no issues. I was the host for most of the time, and this had no impact whatsoever.

Runs perfect but we aware of a dual monitor issue.
Second monitor needs to be at 60hz, otherwise the 2 hour playtime notification will cause a bad FPS drop that requires restarting the game. Disabling the notification will also fix it.
Use Vulkan but it ran fine with DX 11 and 12. Vulkan is also 3 to 5 fps quicker.

When travelling fast via train sometimes some of the blue mushrooms have artefacts around their stems, suspect that's TAA rather than the game though.
Alt tabbing back into the game results in a black screen for a brief time (2 seconds)
Turn off V-Sync or the game will very regularly stutter when moving between regions, and set FPS limit to your monitor refresh.
After doing so on my 4090 I notice very little stutter, and I'm on full ultra settings, no upscaling.
Also performs well on standard proton-ge. Remember to turn off Vsync or you'll get quiote a lot of stuttering.
Do not use mangohud with -dx12 flags, it will not work.
Works great, no issues!
-vulkan
Game slows down when exploding certain rocks. Multiple explosions can result in significant slowdown.

Boot into menu and create a new game. Loads for a few seconds then freezes.
-vulkan
Without -vulkan, it freezes on boot load. With -vulkan, it freezes on game load. Proton version changes nothing. Other suggested launch options either don't make any difference, or prevent the game from even starting. No luck unfortunately.

On occasion the game will freeze for a moment, though this is probably just a quirk with Xwayland.
Just switching to Experimental works for me. Note that I am on Wayland, KDE particularly.

Works out of the box. No tinkering required

If the Proper Settings are made, Launch option plus menu option it runs very good locally, Servers have some graphic issues.
-vulkan
It Runs Well with the options described above, but if you play on a Server that forces Direct x you might experience so colour issue on the mountains far away, the ones not part of the map anymore.
I used the no issues option because You can even get it right on a server, but you need to have admin priviliges and some Providers of gameservers do not let you change that option if you order a gameserver for Satisfactory specifically and not a blank one.
gamemoderun mangohud %command%

Inputs feel slightly laggy? It's very hard to describe.
Performs perfectly well even in large factories just like it should. Only thing I'd say is I was prompted to install the Microsoft .net framework for Unreal Engine, it claimed the install "failed" but it let me launch the game and play so I guess it didn't fail in a meaningful way.
This could also be a proton-cachyos thing.

Great out-of-the-box
Crashes when you attempt to change graphics settings in-game. This happened my first playthrough of the game
I installed steam, then clicked a button, then installed Satisfactory, then... oh, wait. I think that's the end of my list. See above for only significant bug found

It just worked...

Runs faster than a hare

Runs fine
No issues

Never makes it to the title screen; entirely crashing on DirectX and hanging on the loading screen on Vulkan.
-vulkan USEALLAVAILABLECORES -nosplash -NV_PRIME_RENDER_OFFLOAD=0 -VK_LAYER_NV_optimus=non_NVIDIA_only -GLX_VENDOR_LIBRARY_NAME=mesa %command%
As very few others have experienced, the game simply won't start. On DX11 and 12, it shows the splash screen before crashing, while on Vulkan, it makes it to the loading screen before indefinitely hanging. I've tried almost every combination of launch options I can find, I've updated my GPU drivers, nothing works. I may end up re-installing my OS to see if that does anything.

-vulkan
Runs great.

WINE_FULLSCREEN_FSR=1 gamemoderun %command%
it crashed 4 times in over 1000 hours of play
graphical textures missing with certain versions of vulkan

mangohud %command% -dx11
Petit lag à chargement de la map mais ne se reproduit plus après un premier passage et ne dur que quelques millisecondes.
Avec un lancement sans modification sous DX12 une perte de performance de 30% est à prévoir.
