A lot of the emails/notes were a bit small. It's ok for my eyesight, but I did notice I was holding the steam deck closer to my face.
Really good value on the Steam Deck. Thoroughly enjoyed it.

A couple of crashes during the live action episodes, but they can be replayed after restarting the game.
With Proton latest (9.0-4) the live action episodes would start playing but the video would freeze after about 10 seconds, audio continues. Worked ok with Proton Experimental.

Collectible documents may be hard to read in handheld, but not on monitor.
random lag, but only for a few seconds

Video episodes now work fine on Proton Experimental, and apparently even on regular Proton as of the latest update, but I haven't tried it. They are streamed from Microsoft's (poor) servers and can pause to buffer pretty regularly however, no matter how good your internet connection is. Medium settings look good and can net you a pretty stable 40fps with SteamOS built-in cap, but some areas (mostly during non combat scenarios) can drop to the mid-30fps. I advise capping the game to 30fps for a perfectly stable experience if that's what you like, as the motion blur is well implemented and makes the game look decently smooth. Input lag can feel pretty high but that's a quirk of the game itself and feels similar to other Remedy games. Disabling Vsync can help a little with it.

Newest proton version (9-0.3) fixed the issue with streamed cutscenes
Streamed cutscenes now play perfectly with the newest Proton update. Unexpect considering that those don't even worked under Windows 10 & 11...

In Act 2 Part 3, the initial cutscene didn't have any dialog audio at first. Bizarrely, the rest of it (footsteps and SFX) was still there. When I restarted the mission, the dialog played correctly. Not sure if this was a Proton issue or just with the game.
The entire game functions fine. Some reports say the streamed cutscenes are awful quality but they ran fine at 1080p for me, but you do need good internet. You'll have to watch them on Youtube if you have a slow connection, because due to a 5head move from Remedy only the Windows Store version locally stores the cutscenes. From what I understand the live cutscenes only play with GE, so I just played the game with that. The in-game video player is awful and if you try to forward or reverse it bugs out, but I don't think that's a Proton issue. Overall it performs the same as native.
Streamed cutscenes are aweful both on Linux and Windows. The devs decided that localy storing the videos is too hard...

After the recent proton experimental update the bitrate of the movies is fixed. The game is now fully functional and on the deck at medium settings you get a very good frame rate.

Need multiple tries (Alt+Tab/Windows key, etc.) for the game to release the mouse, when losing focus.
On multiple occasions, the game had variadic sensitivity. I'm guessing, this is the game's stupidity, being a console port, rather than running it on Linux.
The game on highest settings in 1080p ran with around 30-40 fps. Don't know if this a Linux+Proton issue, but definitely bad, given the hardware. Lowering them a little yielded stable 60+ fps with very nice graphics still.
The 3d rendered part of the game runs flawlessly. The videos played from local storage (eg.: the "previously on Quantum Break" recaps) play flawlessly. The episode livestream is completely borked. It either doesn't play and show a black screen with the video controls, or crash the whole game entirely. Had to watch them on Youtube.
Livestreamed episodes don't work.

Сериал не работает
There are key choices in the game that effect the story, and these choices have long episodic cutscenes that are played through streaming, and the streaming quality is awful. Unfortunately in Remedy's infinite wisdom only the Windows Store version of the game can play the cutscenes locally.
The only way around this is to just watch the cutscene of the choice you picked on Youtube

Gameplay is smooth and excellent, FMV sections are junk and must be skipped
Streaming FMV sections are completely unwatchable.
I've not played all the way through, so not sure how much missing the FMV is going to detract from the game. What dumbass thought to build such a design where it (badly) streams 50% of the experience? I'm past the cutoff for refunding otherwise I'd absolutely turn this back in.
works out of the box with latest proton

Streamed / live-action cutscenes wouldn't work and had to be skipped
The game is playable and the in-game cutscenes run well. The streamed / live-action cutscenes were unwatchable for me and had to be skipped. I ended up viewing these cutscenes outside of the game.
Worked perfectly with no tinkering on Pop OS through Steam

A good game tarnished by Microsoft's awful servers. Ignoring those, this is an exciting time-travel shooter, with that classic Remedy touch.
If you're sat with arms outstretched, some text on notes and other collectible lore pieces can be difficult to distinguish.
This isn't even a bug, just genuine Microsoft incompetence. After each act, an episode of the Quantum Break TV show is designed to play to accompany the main game, however these episodes do not play and instead leave you with a black screen constantly "buffering" due to Microsoft's atrocious servers. Wouldn't be surprised if these servers get shut down for good sometime soon.
If you like Control or Alan Wake, this might be fun to try out.

Cutscenes flicker intensely in way that could probably cause seizures
Crashes after every live action segment but luckily no progress is lost
Live action cutscenes did not play in vanilla proton but do in GE. The crashes are present in both versions

Playable and stable, Live action episodes work but has video-related issues
Episodes don't show up correctly and goes out of sync with the audio, despite in-game videos plays fine, probably a streaming issue since they aren't saved locally and streaming from a server.

DXVK_ASYNC=1 gamemoderun %command%
Had to upscale because of my VRAM
The game running with upscale goes to 60 fps no problem, but i found out there's a crash problem if you disable "V-Sync" so i had to leave it "on" all the time, Proton experimental runs smooth, GE Proton is a stutter mess for me, but i would say the game runs perfect like Control, the only difference Quantum Break menu doesn't crash on me but Control does and it's random.

stuttering
The game's implementation of VSYNC causes the game to stutter when you pan the camera even with medium settings at a solid 40hz on deck. If you want buttery smooth gameplay: disable ingame VSYNC, make a textfile called dxvk.conf open it and add the following line: "dxgi=syncInterval = 1" (exactly, case sensitive!) save the file and move it to the game's main directory (not the \bin folder) where the *launcher.exe file is located. This forces proton vsync instead. No more stutters. Enjoy!

DXVK_ASYNC=1 gamemoderun %command%

Reduced graphics to medium though the Steam Deck can champion max graphics
Game crashes when tries to play the TV show segments
Game crashes trying to play the TV show segments but they are available on youtube

Missing live action video
Current proton version (8.0 I think) causes everything to freeze when game is focused. Downgrading to 7.0-6 fixes it. Issue with blank screen for live action video that others reported is there though. Atleast at the end of chapter one, haven't gotten further.
Closes after pressing play

works fine apart from broken live tv cutscenes. if you want a just works no issues experience, it's not there yet.
game bug not linux specific: mouse look is broken
live tv cutscenes don't work. need to watch on youtube
Live action episodes won't play
It works on my Steam Deck, but not on my Threadripper/Nvidia machine
taskset -c 0-5 %command%
The fact that it works on my Deck leads me to believe that it's one of those games that breaks when you run with many cores, but "taskset -c 0-5 %command%" to limit it to the first 6 cores didn't help, so now I'm S.O.L. on my main gaming machine. :/
The live action videos didn't play, except for the recaps.
QB is a straightforward experience. Before I added `gamemoderun` or ASYC, game worked fine as well. Just install it and play.
DXVK_ASYNC=1 gamemoderun %command%
Sometimes some textures flicker. It's rare and for a second or two.
Game works on Intel Arc like it should. No game breaking bugs, good framerate, can be played using a controller. In overall it is a good experience.
It just works, click to play and enjoy your game!
Crashes when gathering the feed for the live serie, every episode. But saves your progression before crashing so the issue is not too bothering (you can watch the episodes on youtube anyway).
Plays very well on my system. Very few issues, none if you forget about the ingame serie part. Which is not gameplay.
If you don't mind ignoring the TV Show version of the story and are willing to put up with occasional crashes this runs as good as windows.
WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGER=1 DXVK_ASYNC=1 WINE_FULLSCREEN_FSR=1 WINE_FULLSCREEN_FSR_STRENGTH=2 WINE_FULLSCREEN_FSR_MODE=ultra gamemoderun taskset -c 0-9 %command%
The game seems to freeze and crash when you reach the end of a act and sometimes very rarely the end of a part. However this happens after the game has already saved that you beat it and isn't a problem other than a minor annoyance.
The startup parameter WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGER=1 does fix videos in this game, however the TV Show aspect of the game is just a black screen (This might be some online DRM issue)
If you don't tinker most videos are either black or corrupt when playing, and the crashing is pretty bad. But if you love these types of games you will still enjoy the game. I'm using AMD FSR as the built in upscaler hurts performance and looks worse at 1440p
DXVK_ASYNC=1 %command%
Qorks fine
O jogo funciona normalmente, exceto as live action no final de cada capítulo, mas elas são apenas um conteúdo adicional
DXVK_ASYNC=1 %command%

The game has quite good performance to start playing

Other then broken online episodes (that are watchable on youtube) it ran suprisingly well (medium preset). Some very minor performance drops
Some stuttering in cutscenes
Online episodes between chapters don't work: black screen and stuck buffering. Other cutscenes / movies work fine

I wasn't able to get 60fps but I was able to get a very stable 30fps with everything set to medium.
