Best Batman: Arkham Knight Settings on the Steam Deck

Short version: Batman: Arkham Knight is Deck Verified, and community reports put it around 45 fps on the Steam Deck at the default resolution. That is a good baseline for an open-world action game on a 15 W handheld, and it means no drastic compromises are needed — cap a little under the average, switch off the GameWorks effects this port is infamous for, and trim shadows. That is most of the work.

A note on honesty: the 45 fps above is community-measured, from a single player-submitted report at the default resolution. It is not a benchmark we ran, and it is a directional signal rather than a per-scene guarantee — storm-heavy story missions will sit lower than quiet rooftop gliding. No setting below carries an fps claim, because we have not measured one.

The frame rate cap

Give Gotham a fixed ceiling instead of letting the frame rate wander with the weather and traffic.

1. Open the Quick Access menu (the … button) → Performance tab.
2. Turn on Use per-game profile so this applies to Arkham Knight only.
3. Set Framerate Limit to 40 fps (45 fps on the OLED).
4. Set Refresh Rate to 40 Hz (45 Hz on the OLED).

The measured average is close to 45, so a 40 cap sits comfortably under it — you get flat frame times through combat and traffic instead of a number that drifts. Matching the refresh rate to the cap is what makes it feel smooth rather than juddery. The LCD's refresh slider runs 40–60 Hz, so 40 Hz is native there; the OLED's 90 Hz panel only goes down to 45 Hz, so 45 fps at 45 Hz is the equivalent pairing on that model. In-game, set Max FPS to 60 and let the SteamOS limiter do the actual capping.

In-game graphics settings

Start from a mid preset, then deal with the settings that matter on this specific port.

• Interactive Smoke/Fog, Interactive Paper Debris, Enhanced Rain, Enhanced Light Shafts: Off, all four. These are the NVIDIA GameWorks effects, they run heavy on AMD hardware, and Gotham is rainy and smoke-filled for most of the story. This is the highest-value change in the whole menu.
• Shadow Quality: Medium. The biggest of the conventional levers — Gotham's skyline and street lighting cast a lot of shadow, and dropping from High buys real stability for something you will not notice while gliding.
• Level of Detail: Medium. Draw distance across the city is a real cost at handheld viewing distance.
• Texture Resolution: Normal or High. The Deck's 16 GB of unified memory is not the constraint here.
• Motion Blur: Off. A frame-time cost for an effect most players switch off, and it makes fast Batmobile sections harder to read on a small screen.
• Chromatic Aberration / Film Grain: Off. Free, and the image gets cleaner.

Upscaling on Deck

Arkham Knight predates FSR and has no upscaler in its own menu, so use the one SteamOS provides: drop the in-game resolution one step below native 800p, then set Scaling Filter to FSR in Quick Access → Performance and tune the sharpness. This game's third-person camera and heavy rain-and-haze post-processing hide upscaling softness unusually well, so it is close to free headroom for the busiest street and rooftop scenes.

TDP and battery

This port leans on the GPU more than the CPU, so power tuning is worth doing once the cap is set.

• TDP Limit: try a manual 9–11 W. If 40 fps holds there, leave it for the longer session; if you see dips, raise it a notch rather than uncapping the frame rate.
• GPU Clock: automatic, unless you are chasing the last bit of consistency. Manual clocking is a fine-tuning step, not a first move.
• Screen brightness: Gotham is a night game, so you can usually run a step or two dimmer than you would expect without losing legibility.

The 15 W APU ceiling is the hard limit either way — this is about where inside that budget you park the game, not a way around it.

What the compatibility signals say

Two independent signals agree here. Arkham Knight carries a Deck-Verified badge from Valve, and it holds a Platinum rating on ProtonDB from several hundred community reports — which is a statement about Proton and SteamOS compatibility, separate from the fps figure above. Between them, this is one of the more dependable open-world titles to install and tune rather than fight.
