The only problem I had was with proton-CachyOS(native package) when I was using expressVPN. The game wouldn't connect to other players and vice versa(even with friend that you could see online). The problem was fixed after I switched to proton experimental.

It runs extremely well and smoothly.
There is crackling and distortion with very loud audio moments while diving onto the planet, but it is otherwise fine.
I run in Borderless Full Screen Window mode and when the opening cinematic starts it does not always launch and occupy the full screen. I have found the most reliable way to switch over to it is to click on the bottom portion of that window when I pops up while I hover over the Steam icon.

symlink my ~/.steam/steam/steamapps/compatdata to the install disk (new disk for steam)
ln -s /home/[username]/.steam/steam/steamapps/compatdata/ [path/to/disk]/SteamLibrary/steamapps/compatdata
white borders on borderless and fullscreen
often faulty cursor grabbing but not always (like sometimes while running)
after symlink due to new disk this worked very well out of the box, exept cursor grabbing. also running a 90fps at max setting native rendering but was expecting a bit more given my build.
tried default, hotfix and experimental versions of proton, with or without arguments, did not wok
gamemoderun %command% --use-d3d11
Works pretty well
gamemoderun %command% --use-d3d11

Mods have been broken by the recent update
Any mods changing (at least) models will cause the game to not launch. Delete the data direcotory, then verify installed files. Also update your mods.

Weird white line around screen in Fullscreen. To Fix (KDE): run game in window mode and use special application settings to force fullscreen.
When using multiple Monitors, the mouse sometimes moves out of the game. To Fix: disable all other monitors. In KDE, you can set keyboard shortcuts for this.
First, figure out your display name: "kscreen-doctor -o"
Then create a new shortcut with the command "kscreen-doctor output.[monitor].disable"
and another one with "kscreen-doctor output.[monitor].enable" to enable the second monitor again.

Plays great without any changes, but there are minor performance issues that can be helped with tinkering
gamemoderun gamescope -w 1920 -h 1080 -r 165 -f -- %command% --use-d3d11 -USEALLAVAILABLECORES --force-grab-cursor
Illuminate shields are improperly rendered and have black boxes in the texture even when close
Mouse is not trapped to screen in borderless windowed, --force-grab-cursor
appears to help
Reduced frame rate compared to windows --use-d3d11 -USEALLAVAILABLECORES
partially alleviates and increases frame rate slightly from ~120 fps to ~140 fps
If you use a different keyboard layout (I use colemak) gamescope
translates your layout to the game automatically and you do not have to rebind default keys.

Not going to go
I am on Fedora 42 and game not going to work no matter what i do

gamemoderun gamescope -w 2560 -h 1440 -r 165 -f -- %command%
borderless has a weird white outline without the launch options
performance since some recent update (idk which one) has gotten WAY worse, went from matching windows performance to anywhere from 20%-50% worse performance than windows, making the game kinda unplayable

DRI_PRIME=1
Helldivers 2 previously required no launch arguments for Fedora, but now it is not using the GPU - unless this launch statement tells it to use the GPU. I have seen this on other games such as Forza Horizon 5 lately, so it is likely no fault of the game.

The game window appears, but closes itself very quickly
Seems like the recent patch broke the game on Linux entirely
gamemoderun %command% -USEALLAVAILABLECORES

Borderless has white lines
Plays fine for me without any modification, but YMMV.

gamemoderun %command% --use-d3d11 -USEALLAVAILABLECORES
Some things jitter around, some textures are pixelated or blurry from time to time, and enemies occasionally have bugged (ha) geometry
Borderless fullscreen has a 1px white border

Sometimes, when you Alt+Tab and then refocus the game, it becomes really stuttery. You might want to Alt+Tab a few times until it fixes itself, that usually works. Also, there's the white border in borderless mode, but I think it's the same on Windows.

small update: gamescope -w 1920 -h 1080 -W 1921 -H 1081 -F fsr -f -- %command% will remove the 1:1 pixel border from the game

I had crashing after about 2-3 minutes starting up. I ended up disabling the XMP profile and lowering my RAM clock rate from 6000 MHz to 4800 MHz in the BIOS. Avoid overclocking your RAM for this game. Now it works like a charm!

mangohud %command%
It doesn't start on fullscreen by default, need to enable it manually.
If ASYNC option is enabled the input gets laggy after two missions and worse while in it.
Performance-wise Helldivers 2 runs slighty worse on linux than windows, have to keep it most of the graphics on low.
If ASYNC option is enabled the game will drop FPS after some time playing.

White border in borderless screen
Noticed RAM is used a bit more

There is a white border in windowed fullscreen mode. In default fullscreen mode everything is fine
Game works flawlessly without gamescope. i tried to use gamescope on wayland with SDL backend and X11 synchronous to avoid default fullscreen mode behavior but game randomly freezes at esc menu.

Le jeu fonctionne génralement très bien. (Sauf quand ce sont les développeurs qui font du caca, ce qui est arrivé dans le passé. J'ai joué 444 heures / j'ai atteinds le niveau 112).

Works pretty well, but could be better (also, better performance on CPU bottlenecked systems).
There appear to be some missing textures (some weapon magazines, tip of artillery shells).
Bordelless fullscreen was overriden by the task bar. Fullscreen had issues alt tabing.
Apart from the issues presented, the performance boost is welcome for CPU bottlenecked systems.
The first time I run the game it was slow(15/10FPS), after restarting it never happened again.

I played the game on windows alot and it runs exactly the same except for a small performance increase and pretty much no stuttering, i noticed a specific visual bug with the text when you lose connection and or the game you're trying to join is full the text is misaligned but it could just be a problem with the game, would highly recommend giving this game a try on Linux

Great game and works well for me in Linux Mint 22.1. Might take some tinkering to get it working right but nothing too extensive.
Only runs in fullscreen windowed mode, with the 1 pixel white border. Otherwise, no issues.
Mouse will leave the game window at times and leave me confused as to why my character is no longer responding. Quickly corrected by clicking back into the game most of the time.
Had some initial problems that I think were related to older video drivers. The game would start stuttering when the computer uptime got past a few days. Since the driver version listed in my current computer config, the issue seems to have been resolved.
With current drivers and the OS updated as well as everything else, the game has been running with minimal issues. Biggest annoyance is the mouse cursor leaving the game window sometimes.

Works better on Linux than windows, at least for my hardware. When I play on windows I crash frequently, on Linux I have not had this issue.
1 pixel white border, known issue and not noticable while playing tbh

--use-d3d11 -USEALLAVAILABLECORES
Set graphics settings to Performance. Runs really well.

choppy audio unless add delay
stutters occasionally

PULSE_LATENCY_MSEC=30 WINE_CPU_TOPOLOGY=8 LD_PRELOAD="" PROTON_ENABLE_NVAPI=1 mangohud gamemoderun %command% -USEALLAVAILABLECORES
- had to add

in my case
- after a while (~1h) my mouse movement to look around would stutter. Had to add

- performance was a bit off. Had to add

As of this review https://www.protondb.com/app/553850#oxqTZJNqRi , tinkering with the wine registry to prevent mouse cursor escaping the game window.
Sometimes the enemies have strecthed out polygons.
Mouse cursor escaping the game window on borderless fullscreen. I'm using 2 monitors so it's obvious and annoying.
Proton GE already has the proton fix for the window problem but need to wait for a new release, as of this writing.
Works great
This tinker:%command% -USEALLAVAILABLECORES --use-d3d11 -force-vulkan=black screen after license agreement-no tinkering works fine

I have had issues with black screen on fullscreen and odd single pixel wide borders in borderless fullscreen.
Stuttering after some time playing, very annoying and noticable
This game got so many, but I don't know if they are Linux issues or not.
I generally find the game enjoyable, despite the technical issues the game faces.

Borderless Fullscreen has a white border, fullscreen works normally
No tinkering done and the game works as it did on windows

game-performance %command% -USEALLAVAILABLECORES --use-d3d11 -force-vulkan
Changed to protonGE 9-25
The game can get stuck in black screen if you use fullscreen / theres a subtle white border in borderless fullscreen
No annoying problems except for the cachyOS proton version, had to change do protonGE 9-25 to be able to play online. Performanc wise its awesome :)
