Best Dark Souls III Settings on the Steam Deck

Short version: Dark Souls III is Deck Verified and runs comfortably on Steam Deck hardware — community reports put it around 45 fps at the default resolution. It is older and lighter than FromSoftware's open-world titles, so this is not a game that needs drastic cuts. Cap at 40 fps with the screen at 40 Hz on the LCD (45 fps at 45 Hz on the OLED), trim two settings, and you spend the whole game at an evenly paced frame rate.

A note on honesty: the 45 fps above is community-measured, from a single community report at the default resolution. It is not a benchmark we ran and it is not a floor — spell-heavy boss arenas will sit under it, empty corridors will clear it. We have no per-setting fps numbers for this game, so nothing below claims one; the settings advice is general Deck practice for this engine's known costs.

Cap the frame rate and match the refresh

Dark Souls III has a hard 60 fps engine cap and ties some physics and animation timing to frame rate, so there is no uncapping it and no reason to try. The in-game Frame Rate option only offers 30 or 60 — leave it at 60 and do the real capping in SteamOS, where you can pick 40.

1. Launch the game once, reach the main menu, then return to the Steam UI.
2. Open the Quick Access menu (the … button) → Performance tab.
3. Turn on Use per-game profile.
4. Set Framerate Limit to 40 fps (45 fps on the OLED).
5. Set Refresh Rate to 40 Hz (45 Hz on the OLED).

A 40 cap sits under the measured average, so it is a number the hardware can actually sustain instead of one that spikes to 45 in a corridor and sags in a boss arena. Matching the refresh rate to the cap is what makes it feel smooth — every frame gets the same 25 ms on screen. The LCD's refresh slider runs 40–60 Hz; the OLED's 90 Hz panel stops at 45 Hz, so that model pairs a 45 fps cap with 45 Hz for the same even pacing.

In-game graphics settings

Open Game Options → Graphics. This is not a game with a long list of expensive sliders, so the goal is trimming the few that actually cost frames in Irithyll, Lothric Castle, and particle-heavy boss fights.

• Texture Quality: High. The Deck's 16 GB of unified memory handles this easily and textures are cheap for what they give back.
• Effects Quality: Medium. The most likely cause of hitching in spell-heavy fights — trim this first if combat feels rough.
• Shadow Quality: Medium or Low. One of the bigger frame-time costs in this engine and hard to miss on a 7-inch screen.
• Reflection Quality: Medium or Low. Wet surfaces are everywhere in this game's world and are a reasonable place to save.
• Antialiasing: TAA. Cleans up edges cheaply and is worth keeping.
• Depth of Field / Motion Blur: Off. Both cost frames for effects most players switch off anyway.

Leave everything else at the preset. A handful of changes gets you most of the headroom this game has to give.

Battery and TDP tips

At a 40 fps cap this is not a power-hungry game, so there is real room to tune below the Deck's 15 W ceiling.

• TDP Limit: try 8–10 W manually. Dial down until you see dips, then nudge back up a watt.
• GPU Clock: leave it automatic first. Only set a manual clock if you still see stutter with a TDP limit in place.
• Screen brightness: the biggest battery lever on either model, and this game's dark stretches — the Catacombs, Irithyll's underside — hide a dimmer screen well.
