- Audio is crackling with latest versions of Proton Hotfix and Proton Experimental. Even the latest (at time of writing) GE-Proton9-20 has some major audio issues at various points in the game. Download and configure the game compatibility to use the older GE-Proton9-16 and the audio crackling is almost entirely fixed (with the exception of a few very minor points in the game). I tried a few versions, this is the latest version that worked for me. Versions 9-2 to 9-16 seemed fine, then 9-17 has borked audio again.

Audio is crackling with latest versions of Proton Hotfix and Proton Experimental. Even the latest (at time of writing) GE-Proton9-20 has some major audio issues at various points in the game. Download and configure the game compatibility to use the older GE-Proton9-13 and the audio crackling is alomost entirly fixed (with the exception of a few very minor points in the game). I tried a few versions, this seemed to be the best for me.

a few moments where the frame rate dipped slightly, nkt by much though.
FSR is a good idea for steam deck. Audio was initially crackly but stopped on Proton 9.0-3 and when it was done rendering the main-story shaders.

Tarda en cargar algunas texturas
FRS3 Obligatorio

Significant FPS drops anytime there's spores present.
The game ran at a solid 30 FPS and was running mostly fine with some FPS drops here and there but once you get to the first mission where you have to kill some infected in the spore filled rooms the audio degrades and the game completely stops working it runs at 4FPS when it does work and when it does the game just crashes/freezes causing you to force restart the Steam Deck.

play this game on pc

V-Sync - Off // Framerate Cap - 40 // Scaling Mode - "Default" not FSR // Render Scale - 70 // Sharpening - 50 // Film Grain Intensity - 0 // Steam Framerate Limit - 30 // Steam TDP Limit - 9
I chose to lower the resolution to 560p instead of using FSR as FSR produces a lot visual artifacting on moving objects in this game leading to very fuzzy image. The sharpening filter and default anti-aliasing help create a stable and reasonably sharp image at 560p while maintaining 30fps. // The in-game framerate cap was set to 40, as setting the cap to 30 causes poor frame pacing. You can disable the cap, but doing so will impact performance. If you choose to target 40fps instead, I would recommend changing the in-game framerate cap to 50. // I limited the tdp at 9 to provide 2.5 hours of battery life, though you could easily remove this cap and use the extra performance to target a higher resolution or 40fps instead.

game runs great @ 30fps, you can reach up to 45fps by turning off vsync and adjusting film grain and motion blur!
The game runs (mostly) at 30fps stable if you cap it, at some places the fps drops between a range of 20-29fps on version 1.0.4
At some parts of the game when fps goes lower than 30fps you can hear crackling, doesn't happen often.
In certain parts the game can run at arround 20 - 29 fps average
Rarely the ground disappear and some graphic artifacting and lesser graphic artifacting.
Finished the main game and left behind only on steam deck in version 1.0.4, game runs mostly at 30 fps with a few places where it drops for example inside buildings, underground places, rarely in intense focused sections of the game. No crashes or heavy graphical glitches encountered but a few and rare lesser graphical issues found at some places.
I suggested to still use the proton version that steam recommends (Proton Hotfix), using another made my game lag.
Overall, the port is playable from start to finish without major issues and mostly 30fps but expect drops, I suggest still waiting for new patches to have a more stable experience with this game specially on the deck.
Despite trying when it was first released, the game ran much smoother after the 3rd patch or so. Got a relatively stable 30 fps on low.
Dips to 20 fps in sections. Crashed once or twice.
Much more stable now than at launch. I'd probably wait for another patch or two before diving in but I managed to play through it in its entirety with a relatively stable 30+ fps
30 FPS limit, FSR
Game crashed when trying to slide between a bookshelf, had to restart steam deck. Played on PC to advance to further point in the story to avoid that area on the deck again.
Wait for a patch. I have waited for shaders to load 3 times now because I didn't advance far enough in the game to avoid dealing with them again at a restart. Due to shaders taking 20+ mins to load, this game does not respect your time enough to justify the tinkering to get it to work properly.
In some areas where there's a lot of object it drops to 18-20 FPS.
Sometimes the steam deck would freeze at play - I'd have to turn it off and on.
Shaders were compiling like for total of 60 minutes
The game is great, but it spoils the optimization. Wait for the patch.

Runs well on cutomized low/medium settings & FSR performance mode. Shaders took 30 minutes to build. No crashes 3h in the game...
Fixed framerate to 30 FPS
Fun to play, with visual quality lacking a little. Shaders took 30 minutes to build. I don't regret buying the game.
The game runs on customized "Low" setting with some adjustments to medium and the character details set to high. FSR is set to Performance (640x400 upscaled?) and 30 FPS fixed. It runs at 25-30 FPS. Compared to games like Witcher 3 or even Control it looks a bit low quality and at times textures seem to be missing on some objects ocassionally. But the gameplay is captivating and I'm enjoying the overall experience.
The shaders took 33 minutes to build. I set the framerate to 15 FPS and everything to Low / Ultra Performance. Not sure if that did speed up things, but the fans stopped spinning so it did have some effect on the system load.
WAIT FOR SHADER BUILDING TO COMPLETE. Even on Windows PC, this is needed. Proton Experimental, otherwise, used all default settings. 25fps
Occasional Complete Steam Deck Freeze - Had to force power off
It's playable, but may need to reduce quality to increase FPS. I try to use all defaults first and I found the 25fps playable, but just barely. For me, it stays very solid at that 24-27fps. All sound was fine; pretty good through my headphones. The Shader Building is painful and can take between 20-70 minutes. There seems to be a wide range of times being reported for that. I left mine plugged into power and it finished in about 30 minutes.
wait for a patch. its not playable right now
Change the graphics settings to low. Battery will last around 1h:30m
For now it is just 15 minutes of watching nice cutscenes - crashes won't allow you to play past the prologue
Connected DualSense by USB does not enable "vibration" features, stating that I need to enable "sound output through DualSense" - however even explicitly setting audio output to it won't help.
However, the inbuilt Steam Deck controller support was phenomenal - no issues (they even provide a special layout with Deck images and icons!). The only thing was missing is ANY vibration (Deck has something like both-edge vibration motors - they could add at least some sort of extended vibration, ND even state in the game about "DualSense and other compatible controllers").
While stating that TLOUp1 will be "verified" on the Steam Deck - but the "default" graphics preset (Medium) barely handles 20-25 frames on the gameplay scenes. Cutscenes are solid 40fps and work like magic.
You can't progress past the prologue (where the initial credits of authors and all that "Fireflies" slogan) - the game will crash and REBOOT the Steam Deck.
Shaders were compiling like for total of 69 minutes (like Uncharted, but x2 more). Without compiling, FPS was barely above 15 due to 100% CPU usage.
This review was written on launch day of the game and as of right now the game is 100% unplayable on the steam deck.
Reduced graphics to Low with FSR2 Performance
noticable screen door effect because of such low resolution with FSR2
dips to 20fps, absolutely unplayable on Steam Deck!
Initial Shader complie on main menu takes over 1 hour to complete and tends to happen again on subsequent launching of the game.
Avoid purchasing this game if your goal is to play it on the steam deck, performance is bad and will render game unejoyable.
Ran flawlessly with the default detected graphical settings, and no compatibility changes. The game even prompted with the Steam Deck controls, showing it was clearly designed with support in mind. Currently it's listed as unknown, but don't be too surprised for it to become Verified very shortly.
