Flickering textures
Used CryoUtilities default settings + 4gb vram set in bios Settings - low+most effects on, 60 fps, vsync on.
11 hours in:
GE9-16 - a few flickering textures here and there, no audio glitches, no crashes
GE9-20 - lots of graphics glitches and crackling audio
Ergo = use the 9-16 version

Proton 7
Limit to 30 FPS
Would freeze when getting to Chapter 12 in the story
Kept crashing at the beginning cutscene of Chapter 12 until I switched to Proton 7 and set an FPS limit to 30. Now it at least runs and is playable.

Raise de Vram for better cutscenes
FPS set to 30 and TDP at 11W
Severe FPS drops during certain cutscenes
So the big issues for the cutscene frame drops comes down to the Vram 1gb limit. Change it to 4gb and never had a slowness issues during cutscenes.

All graphics set to low.
V Sync- On Frame Rate capped at 30 Display options, increased AMD to Ultra Quality

For some reason, the cutscene right before Chapter 1, where they enter the Nova Net, goes haywire with a FPS going as low as 1-2, and menu's lagging. Plow through it, it's the only instance in the game so far this happens (all other cutscenes run just fine), and it goes back to normal when gameplay starts. If not, restart the game and it'll start after the cutscene thanks to auto-save. It's not related to graphical settings.
After some testing and experimenting, these settings run just fine and looks rather nice! *Display:
- Max refresh rate: 40.00
- AMD FIDELITY FX CA SHARPENING: 50%
- Resoltion Scale: 80.00
*Graphics: Everything on low/off, bar:
- SCREEN SPACE REFLECTIONS: on
- DEPTH OF FIELD: on
With these setting, it looks and plays great and pretty smooth, with occasional dips into the 30's and on rare occasions the higher 20's. First impressions aren't good, though: the very first shot of the zoom-in on Quill's hole has a FPS in the 20's, and the aforementioned cutscene before Chapter 1 falls apart. However, this is nor representative of the rest of the game.
It plays and looks better than I had dare to hope after some experimenting.

Game is poorly optimised. Needs to run with low settings, FRS1 set to performance and FPS to 30.
Some games run well on Steam Desk. This is not one if them. You can achieve 30fps, but with a big trade-off in visual quality. It's playable, though.
Changed VRAM in the BIOS settings from 1 to 2 gb

Models are occasionally shaky.
Game freezes during cutscenes, and can no longer progress.


Got the game as an epic games giveaway. Installed the game with lutris. Used Proton-GE 8.23 and 8.30, Proton 8 and Proton Experimental, but none of them worked properly due to the huge framedrop in some cutscenes and at the beginning of chapter 12. At those points, the device was very unresponsive... some sort of maxed CPU consumption...
But I've got the game to run smoothly with Proton 7!. I've only noticed a few graphic glitches, like sporadic flickering shadows.
30fps and decreased CPU power consumption
Just needed to add this "-nolauncher" argument in Epic Games configurations
flickering shadows
Huge framedrops with Proton 8 and Proton Experimental
The game runs great!

On SteamDeck capped to 45fps to avoid annoying bounces, runs fairly stable at this on low settings and the built-in FSR is nice. Definitely a playable and nice experience, have seen others recommending an FSR2 mod so might be worth trying that to clean up some of the light bluriness.
FidelityFx Super Resolution 2.2 - https://www.nexusmods.com/cyberpunk2077/mods/3001/
Ultimate ASI Loader - https://github.com/ThirteenAG/Ultimate-ASI-Loader/releases/tag/x64-latest
Use FSR 2.2 Mod - https://www.nexusmods.com/cyberpunk2077/mods/3001/
Do NOT use an anti-ghosting version. Place the following files into the bin folder inside the Guardians of the Galaxy Steam Folder: EnableSignatureOverride.reg, DisableSignatureOverride.reg, nvngx.dll, nvngx.ini, and the entire plugin folder.
FSR 2.2 Mod NEEDS an ASI File loaded - https://github.com/ThirteenAG/Ultimate-ASI-Loader/releases/tag/x64-latest
To load the ASI File, you need to Ultimate-ASI-Loader. Go to the link and download bink2w64.zip, and extract the file. Rename original bink2w64.dll file that is in the game's bin folder to bink2w64Hooked.dll, and place the newly downloaded file into the bin folder, where the old file was.
Activate registery modification
Download Protontricks from the discover store, grant it access to your games, and select guardians of the galaxy. Then select Select the default wineprefix. Select Run regedit. Select Registry on the top left, then Import Registry File. Import the EnableSignatureOverride.reg file.
If Protontricks cannot access your game (such as internal drive .local installation):
Open Protontricks, select guardians of the galaxy, then select: Select the default wineprefix. Then choose run winecfg, select drives, and select show dot files. You can now access the internal drive with the game on it.
FSR 2.1 Nexus Mod
60 HZ 60 FPS allow tearing
FSR 2.1 Nexus Mod
To improve power usage I use the following settings: Deck settings: 60 hz Refresh, 30 fps lock, allow tearing, TDP 8, GPU Freq 1000 Display Settings: 1200x800, vsync off, max refresh 30, dlss quality, sharpening 80% Graphics settings: 4x Anisotropic, detail medium, shadow low, texture high, reflections on, motion blur off, radial blur on, chromatic off, lens flare off, depth of field on, light scattering low.
Produces mostly locked 30fps, ~17w of battery usage
Blurry/Soft graphics with FSR 1.0 (default), cleared up with FSR 2.1 mod + graphics settings increase
The game runs well out of the box, but with worse visual quality to maintain framerate and battery (low settings maximum imo)

This game is unfortunately poorly optimized. Worth playing on a Gaming PC or Laptop, but on Steam Deck it's just not fun (for now at least)
Unfortunately can't run this at steady 30fps, even with FSR 2.0 Community Patch installed and running in balanced. Played it on a Gaming Laptop instead, great game!
Installed FSR 2.0 per this article:
https://www.techpowerup.com/review/marvel-s-guardians-of-the-galaxy-fsr-2-0-community-patch/
Some light flickering. Solved by installing an updated version of VKD3D, though I opted to use the latest version (at the time) of ProtonGE.
I ran the game at 60Hz/30FPS. There were some FPS drops here and there, but nothing extreme. Still very playable and a really enjoyable game on the Steam Deck.
flickering texture problem was caused by vkd3d-proton but is now fixed https://github.com/HansKristian-Work/vkd3d-proton/pull/1147
You have to compile you own version of vkd3d-proton with the updated files then copy the new files (d3d12.dll) in the prefix of the game

Grazie alle ultime migliorie in Proton, il gioco può essere eseguito su Steam deck senza la necessità di nessuna configurazione particolare. Il alcune aree c'è uno strano glitch nelle luci, e questo è probabilmente il motivo per cui attualmente è marcato cone "giocabile", ma il gioco offre comunque una esperienza eccellente su Deck

Thanks to the last improvements in Proton, the game runs out of the box on Steam Deck. There's still a wierd glitch with the lights in some scenes and that's probably why the game is marked as "playable", but it's still a great experience on the Deck
