Borderlesss window mode doesn't work on KDE Wayland
Severe mouse lag after the mod support update.
Fixed the horrible lag by deleting the idtechLauncher.exe from the game root directory and create a mock symlink pointing to the DOOMEternalx64vk.exe

Only works when specifically picking 10.0-2 Proton in the Compatibility tab, other versions don't work (including Hotfix and Experimental).
Before PC Mods update, game ran well with Proton 9, even if it didn't launch with default options. Now, since the Mods launcher was added, it needs Proton 10.0-2 to start the game - otherwise, nothing shows up. In the "Compatibility" tab, Proton 10 is at the bottom of the version list, so you must scroll all the way down to pick it. After doing that, everything loads again and works wonders.

New launcher with mod support causes CTD at launch, fixable by circumventing the launcher e.g. via
cd <local file location>
mv idTechLauncher.exe idTechLauncher.exe.bkp
cp DOOMEternalx64vk.exe idTechLauncher.exe
- Launcher is broken; requires circumvention
- Unable to correctly detect HDR; required
--hdr-debug-force-output
- Proton versions other than experimental had dirty exit; required

The amdgpu driver often crashes if pushed too hard with undervolt, hasn't happen with any other game
The new update adds an launcher allowing anyone to play with community-made mods, haven't try it myself yet. But under any other circumstance, the game worked flawlessly with Proton 9.0.4. Before the update, that is.

Booted up Doom Eternal to try the new Mods on offer. The Mod Manager is a little bit jank and often freezes, but stick with it and it'll be fine. Once loaded in, there may be a bug with attempting to change settings using the mouse. When you click on a setting to change and a context menu should appear, it often flickers and you can't select anything; just use your keyboard to select and change (arrow keys, enter, space, esc).

Some issues in menus to change controls
Unable to login to bethesda from the game due to keyboard issues in menus. The workaround: connect your steam account on bethesda website before launch.
This game used to work great on Ubuntu, but the new launcher they added is really laggy and glitchy through Proton.
Very rare/occasional stutters, but overall very good experience (might be an issue with my config).

The game works perfectly fine after a few hours of gameplay and I don't notice any performance or stability issues, so should be fine.

Capped the FPS to 40.
Text can be a bit hard to read at times, though it's doable.
If you play the game on both PC and steam deck, your config settings sync so it can be annoying to, for example, have to constantly change graphics between max and medium.
Läuft ohne besondere Einstellungen sehr gut.

Works fine out of the box, smooth and stable framerate
The game should have an option to cap framerate, the only option to do it is to use vsync which adds input lag.
Works perfectly out of the box

Works smoothly. The experience is better than Windows because the Windows button works while in-game. Doesn't work on Windows.

I used my Bluetooth headphones, and the audio quality tanked, like I was in a call. If this happens switch your headphones' profile from HSP/HFP to A2DP. Note that you won't be able to use your mic.
There's a minor issue if you launch it through the idTech Launcher. If you click on an item in the settings that has multiple options or you want to change keybinds, the menu instantly closes. This does not happen without the idTech Launcher. You can get around this by using your keyboard to navigate the UI. As for keybinds, leave the mod beta channel, boot up the game, set up everything and copy the DOOMEternalConfig.cfg file to your modded version.

runs good
sometimes blackscreen after alt tab if it has been set to exclusive screen

Had to disable V-Sync, otherwise the framerate was atrocious. Without it, runs just fine on Ultra.

One time a window didn't work (map didn't render on the other side)
Once or twice the game would drop frames and graphical quality, fixed upon pausing and unpausing for a moment or it would resolve itself within a minute

I was trying to force HDR I had my screen flicker in fullscreen but setting it to windowed fixed that. Otherwise this game would run fine in fullscreen.

Launching through gamescope to enable hdr. On Hyprland, 0.49.0 the following is needed in hyprland.conf:
debug {
full_cm_proto = true
}
and gamescope needs to be lanched with the options --hdr-enabled --hdr-debug-force-output

Works just like on windows

Really nice experience, recommended.
I would recommend to connect your Steam account to the Bethesda from their site instead of relying on the Game first startup menu. Apart from the Login, the game runs flawlessly.

Worked out of the box

Light to mild crackling at some points.
Handful of spontaneous crashes.
Flawless, wouldn't be able to tell it's not running natively
Surprisingly runs perfectly out of the box, it just works

From a terminal prompt: sudo su; enter password; paste the command: echo "vm.max_map_count=16777216" >> /etc/sysctl.conf
From Cinnamon menu: Turn-off "Effects"
On Mint, and this is my update after weeks of play: with the two steps noted above I have had no more occasional screen-freeze crashes!

runs out of the box.

didn't work (game crashed), however it still ran incredibly well.
Works Perfect!

No issues what so ever, played perfectly fine, buttery smooth at over 400fps for my setup.
The game run with no issues with the default Proton settings on my setup.

works straight out the box
idk probably just me using comsic alpha

Default controller input wasn't working at first. Switched to a layout I made to add gyro, and that for some reason fixed it.
Yeah, turns out I forgot to delete the launch command that said to uninstall the Frame Gen Mod from when I had the Frame Gen Decky plugin. Runs great.
