Runs OOTB
J'ai eu ce jeu gratuitement alors j'ai pas cherché très longtemps, en tout cas j'ai testé toutes les version de proton dispo dans steam.
gamemoderun %command%

needed to disable shadow half rate in steamdeck performance settings
unreadable text, due to shadow half rate
eval $( echo "%command%" | sed "s/Win32\/Launcher.exe'.*/Win32\/TinyTina.exe'/" )
The game laucher crashes when we hover the mouse over it. The initialization options fix it.
Either Friends-Only or Public worked just fine.
Works great out of the box
My previous report is incorrect. The game runs fine with no issues. When I originally installed the game on my second HDD I found out it was NTFS which steam games don't play nice with. Make sure to install on a EXT4 formatted file system.

Couldn't get past the welcome dialog
Proton 7.0-6 and 6.3-8 get me to the welcome dialog, it freezes upon clicking Continue. With GE it crashes at the launcher, Experimental and Hotfix crash before that. Tried with steam on Gentoo and via Flatpak.
Works fine as expected. There is a need for an in-game setup, but not much other than that.

Proton expérimentale
Quelque instalation automatique au 1er lancement.

Runs fine with GE Proton.. you might have to interract with the Windows installer once during installation.
Does not work
The game will not start at all. I have tried Proton versions 5.0 to 7.0.
Starts good (singleplay)
Played with Proton 7.0-6

預設的解析度字很糊,把解析度設成 2560x1440 就可以解決
解析度沒設成2560x1440以上會看不清楚選單的字

text looks totally pixeated, but can be read
initial resolution was wrong
Getting past the hurdles, it's just a good borderlands game. It's free as of writing this, so go get it!
The game would get stuck on the steam deck start up. Had to restart the deck to fix it.
For some odd reason it wasn't letting me add always on commands so I couldn't turn off the touch screen.
Entering flamerock killed fps for a moment, but isn't consistently terrible.
Didn't get far into the game, just checked if it installed and started up and could get into a game.
Default resolution, Official controller layout
Screen Resolution: 1152x720 Framerate Limit: 45 Refresh Rate: 45
Gamepad not working. Use touch as input on launcher. Configure the graphics on the game.

In about 1 of 3 sessions, the game window stays black. A short sound is played, then it is muted. Apparently there are similar bug reports for the windows version.
I'm using the Epic version, installed via Lutris.

Game runs nicely, without issues
Initial gameplay was laggy but it was due to the resolution not being set right...once fixed, it was working fine with no issues
didn't had the chance of trying the multiplayer

Works fine, was too high fps to play on uncapped.
Have to swap proton versions just to launch it. If the prefix does anything it works again.
Works out of the box for me Running Manjaro (Pahvo) with Gnome 40.4.0 and without Optimus Manager installed/Enabled. It ran on my Intel Chip just fine. I also tried it with my RTX 2070 and it worked flawlessly.

Used proton 6.3-7 and it worked fine. I tried 5.0-10 and that did not work.
If you have high quality textures and/or texture streaming on the game was crashing frequently in multiplayer. After I turned off the texture streaming and reduced to low or medium quality I didn't have a problem.
