Doom: The Dark Ages on Steam Deck: Performance & Best Settings

Quick Answer

Doom: The Dark Ages runs on Steam Deck but requires significant settings compromises to hit a stable 40 to 60 FPS. Use FSR Balanced or Performance mode, drop resolution to 800p or lower, and disable ray tracing entirely. The game is playable and enjoyable on Deck but does not represent the full visual experience id Software designed for high-end PC hardware.

Steam Deck Performance in Doom: The Dark Ages

Doom: The Dark Ages is built on id Tech 8 and is one of the most visually ambitious first-person shooters released in recent years. The Steam Deck's AMD RDNA 2-based GPU with 8 CUs and a 15W TDP was not designed with titles of this calibre in mind, so expectations need to be set accordingly. In practice, at native 1280x800 resolution with Medium settings and FSR Balanced mode, the Steam Deck averages 35 to 50 FPS during combat encounters. Exploration areas are more stable, often hitting 50 to 60 FPS. Boss fights and large-scale combat with many enemies and particle effects are the most demanding scenarios, where frame rates can dip to 28 to 35 FPS. At 40 FPS locked with the Deck's 40Hz display mode, the game is very playable. The 40Hz mode is one of the Steam Deck's underappreciated features: it halves the perceived judder of 30 FPS while being achievable where 60 FPS is not. Set the system to 40Hz, lock the frame rate to 40, and reduce graphics until you maintain that target consistently. ## Best Settings for Doom: The Dark Ages on Steam Deck

Use these settings as a starting baseline and adjust based on your tolerance for visual quality versus frame rate:

Resolution: 800x500 or 720x450 with FSR Balanced or Performance. Rendering below native and upscaling with FSR is essential for consistent performance. Texture Quality: Medium. Dropping to Low saves VRAM but reduces visual quality noticeably more than the performance gain justifies. Shadow Quality: Low. This is the biggest single performance win. Shadows in Doom: The Dark Ages are expensive and the Deck benefits greatly from reducing their quality. Ray Tracing: Off entirely. The Steam Deck's GPU has no hardware ray tracing acceleration. Enabling any ray tracing option destroys performance with no quality benefit. Motion Blur: Off. Improves perceived sharpness and reduces GPU workload. Depth of Field and Film Grain: Off. Quality of life improvements with minimal performance cost. TDP Limit: Set the Steam Deck's TDP to 15W (maximum). The game needs all available power. Reducing TDP to save battery will tank performance below playable levels. Fan Curve: Aggressive. The Deck will get warm running this title. Let the fan run at full speed rather than thermal throttling the GPU. ## Frequently Asked Questions

Is Doom: The Dark Ages officially verified for Steam Deck? As of early 2026, the game has Playable status rather than Verified. This means it runs and is controllable but may not meet all of Valve's Verified criteria, such as default settings being optimised for Deck or all text being legible at 800p. Manual settings adjustment is required for the best experience. What FPS can I expect from Doom: The Dark Ages on Steam Deck? With optimised settings including FSR and reduced shadow quality, expect 35 to 50 FPS during standard gameplay and 28 to 40 FPS in the most demanding combat encounters. Using the 40Hz display mode and targeting 40 FPS locked is the most comfortable way to play. Does Doom: The Dark Ages support FSR on Steam Deck? Yes. FSR is available in-game and is essential for Steam Deck play. FSR Balanced at 800x500 rendering resolution is the recommended starting point. FSR Performance at a lower internal resolution pushes frame rates higher but introduces noticeable softness that some players find distracting.
