Runs smooth without any issues
Significant lag at all times. This will be one of the few games I'll have to stick to Windows on.
Worked great out of box

For the first initial load of the game, I needed to lower the graphical settings from Ultra to Low. Once doing that the game loaded just fine. I was then able to set my graphic settings back to Ultra and play like normal.
If your game crashes on load when first selecting a save, try lowering graphic settings to low for that first run. You can then return to the main screen and set them back to where you like.

Spent more than 2 hours playing this game on Nobara 41. Pretty solid experience overall.
None
Some textures are not properly rendered, probably due to the slowness of the external SSD since I used SATA/USB converter.

The displayed input switch back to keybaords, the game has this issue in windows as well. Alt+TAB fixes it

Game works perfectly out of the box (even with M+KB). No tinkering needed.
If you use a mouse & keyboard to play this game, it will work just fine. I have not tried using any controllers, even though the game is intended to be played with one. You might need additional tinkering if you want to use a controller, but the mouse and keyboard experience has been nearly perfect. The only issue is that I haven't figured out to reach all the taunts/emotes from the taunt/emote menu with the keyboard.

Works well out of the box so far
Everything worked perfectly. Multiplayer is fully functional too.

Smooth game experience

Works perfectly fine OOTB
57 hours in from start to finished including post game quests. No issues whatsoever.

Deck tanks to 45 FPS every now and then.

33 hours, zero problems
Everything works perfectly fine right out of the box - install and enjoy.

Completely flawless OOTB
Didn't encounter any issues, game ran perfectly fine too.

just work flawlessly
Another great linux game !
Runs well, no issues

I was able to play the entire game start to finish without any sort of issue. And what a fantastic game this is! I highly recommend getting the Ultrawide mod if you have a ultrawide monitor, very simple install and the game looks almost perfect with it (Some status effects show in 16:9 and some character pop ins during cutscene, but nothing drastic).
Mouse control is incompatible with KDE6 at this moment, it causes all mouse movements to be mapped to up and right direction only. Using another desktop environment or window manager (tested using sway) solves the issue.

performance drops a fair bit in towns but not in combat which i have locked at 45fps which the deck maintains no problem
steam is set to run with proton 9 which runs fine

Works perfectly !
Minor issue, but unsure if it's Proton only, or also a Windows issue : mouse cursor does not always automatically disappear after Alt-Tabbing. Clicking properly hides it.
Works straight out of the box

Steam Deck keyboard would not pop up when entering character name. Used PC to get past that part.
I couldn't get Steam Deck keyboard to pop up when entering characters name at the beginning. I used my PC to get past that part.
Otherwise runs well for Steam Deck, with no tinkering.
Works perfectly out of the box
At 1440p I couldn't get the game to stay at a stable 120 or 60 FPS (game was constantly dipping down to around 40 FPS or so, fluctating between there and 50 or so). Changing the FPS cap to 30 remains stable however.

In the towns/villages, the FPS are lower than what it is on Windows, other than that, it runs similarly, for me is even slightly better.

Another report after having finished all the quests. Game runs perfectly!
Amazing game and great compatibility with linux.

In both towns, when looking across, performance drops to about half of what it runs at on windows. Everywhere else, it's on par.
Everywhere else it runs well, except in towns where the fps drop to about half of what it runs at on Windows, when in towns and looking across them, at least on AMD hardware. I'm not exactly sure why.
Otherwise, fully playable on Linux. Love it

Works perfectly ootb.
No performance issues, no crashing, multiplayer works perfectly. Completed the story with no issues, sitting at a little over 20 hours.

gamemoderun %command%
Disable Cloudflare WARP first before playing this game. Because this game using P2P Connection to Multiplayer.
10 hours, no issues

Just finished up the whole story - with the exception of one crash in the beginning all went smooth. Switched to Proton Hotfix, no issues.

SteamDeck=0 %command%
Keyboard Text input does not work if playing in Desktop Mode on the deck. Setting an environment variable forcing the game as if it isn't on a Steam Deck is required to remedy this.
Runs perfectly.
Works flawlessly. No tinkering needed.

The game would not start when using the default recommended Proton. When using Proton experimental it starts fine and works great.
