If you dock your Deck to a TV, the resolution sometimes gets stuck on the 16:9 ratio when you launch the game undocked. This is easily fixed by changing the resolution back to 1280x800 in the graphics settings in-game.
Frame limit to 60 and TDP limit to 10W
GOG Galaxy install script (https://lutris.net/games/gog-galaxy/) with the latest installer from https://www.gogalaxy.com/en/, then install the game from there

dodge on r4
chews through battery very fast

Game stutters frequently during the later parts of the game in the hub area. Since the final boss is fought there, reduce settings to maintain 60fps.

I installed the Epic Store version through Lutris. Whether I ran the .exe through Wine, Lutris, or Steam, it worked perfectly. Recognized my DualSense properly, too.

Runs perfectly out of the box.

I have slightly worse performance compared to windows
but it runs fine given my hardware
It is playable but my problem is my pc resources
Game Ran out of the Box, No Problems
Run's smooth as butter
works perfectly out-of-the-box
Works flawlessly

Controller worked fine after enabling steam input for as a game override.
Game did not launch with any proton version, but booted up flawlessly on GE proton.

Je n'ai changé aucun réglage, le jeu fonctionne sans aucun changement nécessaire

Works very well out-of-the-box
No problems, no flaws, just works

Two times during a complete playthrough I experience that the game suddenly stopped responding to input (one of the times it got stuck/repeated some initial input). Restarting the game resolved the issue.
Game runs smoothly. Controller input is mapped and shown correctly (I'm using an xbox style layout). I haven't tried the game on other platforms, but it ran as if native.
After 22 hour I've finished the game without any problem. Works great out of the box
Works flawlessly OOTB
Runs perfectly out of the box

After a year, it still has the same issues. Such drastic frame-drops on a combat-focused game make it in my opinion unplayable

Game still suffers from random massive performance dips (from 145 fps to 34 or lower). These drops have varying lengths, but they usually last several seconds and happen in both combat and exploration.
It's very odd because apart form that the game runs fairly smoothly, but the experience is very annoying.
Lastly, some information about my setup: I am running Gnome 44.2, on an Nvidia laptop, with the entire xorg session being rendered using the Nvidia card. I also have my laptop hooked up to a second external monitor. I'm using a different SSD to the one I had on my previous report, and tried both proton 8.0-2 and experimental.
To get more than 4h of battery life, you can set fps to 40, TDP to 7w and GPU frequency to 600 which is a sweet spot.
Some very very rare sound crackling.
occasional screen glitches when moving around in the menu

Very much a gold standard for what should be considered "Verified" for SteamDeck. Flawless use out of the box
I didn't bother changing any performance settings, but I was only getting about 2 - 3 hours from full charge, which seems a bit lackluster for a Unity game.
Only real critique as a SteamDeck user is that the character is so small on screen that you can hardly make out animations and details that might be important in combat.
Plays wonderfully. I completed the whole game on my Deck and ran into no problems at all.
Perfect from start to finish, beat the whole game on deck
The game runs perfectly under Proton, just install and play!
I beat the game twice start to finish on the deck. No setting tweaks, default proton, it worked perfect. No slowdowns, no graphic issues, no freezes, no crashes. Suspend works great as well, I used it a couple dozen times. I recommend against running at 40Hz though. I tried it momentarily and frame pacing went a bit screwy that way. 30 fps at 60Hz should work if you need the battery savings.
VIDEO crashes at random moments during gameplay. The game is actually running, as is audio. So you can send inputs and you'll hear it. But video is completely frozen.
I have tried ALL proton version. I have tried disabling every single graphical enhancement. I have tried the game on internal storage and on external storage. I have tried it in desktop mode and in game mode. Nothing changes the fact that at random times the video literally just freezes while the game keeps going on the background. Sometimes making game mode or desktop mode crash after you try to exit the game forcefully.
On default proton 7 that valve chooses the game has lots of slow down in fighting scenes or any scene with translucent or smoke effects. This is fixed by forcing the experimental build.
Excellent overall and looks superb on the deck screen.
Runs great out of the box. Regularly getting 100+ FPS
At one point I had the game tank in performance, though I likely was running low on VRAM or the like. Hasn't happened again since.
Worked right out of box.
Having these random frame drops on a game with a big emphasis on combat make the experience almost unplayable.
In 40 minutes of gameplay, the game has had 4 massive performance dips (from 154 to 42 fps). These drops last several seconds and appear on both combat and exploration for no apparent reason.
Not sure what could be causing this. My pc certainly meets the specs, I have the game running on an SSD, no background programs running, session forced to nvidia graphics, latest drivers, and other games don't have these issues.
