Finished the game, worked great

Working flawlessly out of the box
I just checked the "enable compatibility tool" option and the default setting was "Proton Hotfix", and the game worked flawlessly after compiling the shaders.

Works great, although I recommend capping the fps at 40 or even 30 for less occasional stuttering
changed tdp down to 10w
slight stutters when driving at high speeds or gliding high above the city
A few stutters here and there.

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

The gameplay is nice, dispite the early release of the game.
I purchased the Premium Edition, and everythong seems workink perfectly.

Most Gameworks options are not available, but the game still looks gorgeous without them
Game works well out of the box

Works
The game works out of the box. No tinkering required.

The game has a 90fps cap by default. You can increase the capped framerate like so: www.pcgamingwiki.com/wiki/Batman:_Arkham_Knight#High_frame_rate
I was able to 100% the story.

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

Had issues with other protons. Game would say it was launched in steam but wouldnt actually bring up the game on my monitor. Tried GE-Proton8-3, launched the game from my desktop icon instead of from steam and it worked fine. Played up until you bring ivy to the GCPD with no crashes or bugs.

Might be due to Ryzen 3300u being not that powerful
I have increased my tdp using ryzenadj.
sudo ryzenadj --tctl-temp=95 --stapm-limit=28000 --fast-limit=28000 --stapm-time=64 --slow-limit=28000 --slow-time=128 --vrm-current=180000 --vrmmax-current=180000 --vrmsoc-current=180000 --vrmsocmax-current=180000
Do not use Arkham Quixote dxgi mod if you have < 8 GB ram and integrated gfx card like me. Performance was worse when using Arkham Quixote.

Well optimized game, works flawlessly on Linux.

Completely flawless experience
Runs with no issues

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.

Game runs just fine out of the box. Sadly Nvidia Gameworks does not work even with suggested tricks found over the internet.

Game run just fine out of the box. Tried to enable Nvidia Gameworks with protontricks, winetricks and parameters and nothing worked.

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

Work out of the box

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.

Edit \BmGame\Config\BmSystemSettings.ini. Change MaxFPS=60.000000 to the desired FPS cap.
tweaks are not necessary to play and enjoy the game out of the box.

Works fine out of the box
Worked out of the box! Nice expierence

So, from my last review. I had cleaned my computer and ofc, moving parts around it. It resulted in the UEFI/bios settings reseting, which ofc meant that Above 4G Decoding and ReBar being turned off, which are essential to be on for Arc graphics cards.

Runs perfectly
Läuft perfekt

Constant freezing the next time I play the game. It only happens after I click my mouse one time. Often it freezes so bad I have to restart.
Freezing is a dealbreaker. If somebody has a fix for it, make it clear in report.

Great game, plays great. Loved it
Only thing was I found that the game would crash if I changed the amount of screens connected to the computer while playing, but most people shouldn't have this problem. Would still recomend

Works perfectly at 90 fps without any lags or stutters. Crashed once (may be a me issue)

Subtitles can be a little hard to read because of how small the text is.
Works very well without needing adjustment. No issues whatsoever.
Best batman game, still serving the same experience even on Linux

Great game - gorgeous at 1600p
Choosing a mission in the radial menu sometimes made gross noises in my headphones
Locked up the device a couple times. I think I had maybe one software crash.
Played the whole thing through at 1600p using the 30FPS frame lock and high settings.
