I played it extensively both plugged in and plugged out. It works perfect. The battery for steam deck lasts almost 3 hours when playing.

Can handle 60fps indoors. Outside/open world had frequent dips from stutter to its 30fps+ regardless of settings. 40/45fps was sweet spot
40/45fps limit on steam deck

Some minor slow downs in some of the boss fights & when driving fast in the city but I tended to glide everywhere so not a big issue. The game is a battery eater so I'd reccomend playing plugged in. Overall played great though with default settings and no tweaks.

For veterans of previous Arkham games not used to the new Detective Mode bindings and still has muscle memory, you can revert back to the old by editing the config files.
.
Find "Batman Arkham Knight\BmGame\Config\BmInput.ini", open it via text editor, "ForensicMode" is mapped to "XboxTypeS_DPad_Up" and while "DualPlay" is mapped to "XboxTypeS_LeftShoulder". Just swap dualplay and forensticmode on both entries, then save it and set to read only
.
The only caveat is that the UI prompts will still display the original controls and the game will display a warning upon boot up that config files have been edited.
You can Force 30FPS to 40FPS/hz to maximize battery life. 40hz gives about 2h30m to 3h on my Steam Deck LCD
Micro-stutters:
Batman Arkham is generally a bad PC port when it released. However, with the Steam Deck, it can maintain a solid 60 fps for most of the gameplay, with minor drops to low 40s and high 30s during High-speed Batmobile or heavy open world segments.
.
There are micro-stutters though. For more stability and less stutters and you can install this fix https://sherief.fyi/robin/dxgi.dll, just download and put in the same folder as the game's exe. (Batman Arkham Knight\Binaries\Win64).
.
Just run the game after that, to confirm if its working a reshade overlay will come up once you boot the game. you can close it by pressing Home hotkey or temporarily binding your controller to Home to close it and rebinding it again to default.
Used normal settings, 1280x800 resolution, and 60fps limit with vsync on. turned off all gameworks

Limited to 40fps, turned settings down. Its still a battery eater though.
I fell through a building once, only lost a few mins thanks to an auto save fortunately.

Subtitles can be a little hard to read because of how small the text is.
Works very well without needing adjustment. No issues whatsoever.
Locked it at 40 fps, customized grpahics settings a bit. Total power consumption ended up at ~12 W, that's roughly 3,5 hours of gameplay.

Sometimes the game would not shutdown properly, so had to force-quit it with STEAM+B.

With the default Proton version, the game plays well. In the first part of the game I changed the refresh rate to 40 Hz, but after an hour or so I went back to 60 Hz because I felt that the game was noticeably smoother. I didn't change any settings eventually.

Frame limit set to 30fps/60Hz to improve battery life
Played through entire story including the knightfall ending + all DLC. Ran it at 30fps/60Hz mostly to increase battery life, so not sure whether it could maintain a stable 40fps or 60fps, but it did maintain a solid 30fps, looked great, and played really well.

I would recommend setting the fps to 30 or lower the graphics settings to get a stable experience.

Subtitles can be a little small but still readable.
Crashes if you change the resolution in game. Using the main menu is fine.
I set to a 30 fps cap and it was nice and smooth. You can get frame rates towards 60 but is quite inconsistent.

RADV_PERFTEST=gpl %command%
If you're playing this on heroic games launcher, use ProtonGE and add RADV_PERFTEST=gpl in environment variables for significantly less shader stuttering

If you have this game on Epic Games for free like I did and dont mind occasional stuttering due to shader compilation then this is great
40fps cap, low settings
occasional stuttering probably due to no shader compilation as it is the Heroic Games Version
Installs and launches fine, no Proton tinkering required. Played for 3 hours on Steam Deck with a 30 FPS cap and all settings maxed out, game runs well without major frame rate or hitching issues. Load times can be long on occasion, but not in a way that feels out of place for a game of this scope.


Set FPS capped at 30
Kept FPS at 60 and game would stutter quite a bit. Changed to 45 and experienced occasional Stutter. Set FPS capped at 30 and game ran fine.
Great experience, it runs great at high at 45fps. Some small drops to 35fps when driving in busy areas. Great game to play on the go.
Forced it to 45fps
if you leave the game idle for an extended period it will crash but other than that it plays perfect
Can regularly stay at 45 FPS low settings, but can still have rare dips; better off playing at max with a 30 cap
Limit to 30 FPS
Can't seem to keep a stable 60 FPS especially during the most non-demanding scenes (ex. the intro diner sequence) even at low. Frame pacing issues before and after entering training sequences and when about to start talking to NPC (like when starting a new mission.)
The stutter is definitely not as bad as launch, but game seems to have an issue streaming as when playing inside environments, it runs smoothly, but while in open world, there's very occasional stuttering for a frame or two. If you want an almost locked 30 FPS, turn off motion blur, turn resolution down to 928 x 580p, and turn FSR on with max sharpness.
Game runs perfectly fine right out of the box, no tinkering required. Should be listed as Verified.
Some ingame text is blurry, such as new gadgets as you gain them
When going over challenges ingame, frame rate slow down
Ocassionally crashes once in a while, does not hinder progress however
Detective Text is hard to read but other than that the rest is fine
Crashes every hour just like Arkham City
The game language that I choosed is Spanish Spain for text and voice but the game use Spanish Latam instead of Spanish Spain, If I use Steam on PC with Windows thats not happend
Genuinly haven't had a single issue, perhaps Steams rating is just outdated. The game runs at high settings 30fps with a ton of headroom and around 3 hours of battery
