Best DOOM: The Dark Ages Settings for FPS (PC): Optimized Guide

The best DOOM: The Dark Ages settings lower Ray Tracing Reflections first (the heaviest lever, up to ~52% of your FPS), then Volumetric Fog and Shadows, while keeping Texture Pool Size as high as your VRAM allows and DLSS or FSR on Quality. DOOM: The Dark Ages is a genuinely well-optimized id Tech game, so a short list of settings decides almost all of your performance — get these right and everything else can stay high.

The fast answer: recommended DOOM: The Dark Ages settings

Set these in Options → Video. They target a smooth, high frame rate while keeping the game’s visual identity intact:

Setting	Recommended value	Why
Upscaling (DLSS / FSR)	Quality	Biggest free FPS gain; enable first
Frame Generation	On (RTX 40+ / RX 7000+), if base is stable	Smoothness boost, adds slight latency
NVIDIA Reflex	On	Lowers input lag
Path Tracing	Off (high-end RTX only)	Massive cost; ~20 GB VRAM at 4K
Ray Tracing Reflections	Low or Off	Heaviest lever — biggest FPS gain
Volumetric Fog / Lighting	Medium	Second-biggest cost
Shadow Quality	Medium–High	Up to ~15% FPS
Effect Quality	Medium–High	Up to ~14% FPS
Texture Pool Size	As high as VRAM allows	Where the game’s look lives
Other quality settings	High	Cheap on this engine

Because the engine is efficient, lower RT Reflections → Volumetric Fog → Shadows in that order to hit a target, and leave the rest high.

Ray tracing is mandatory — but tune it

DOOM: The Dark Ages builds its lighting and global illumination on ray tracing rather than traditional rasterized techniques, so a ray-tracing-capable GPU (RTX 20-series / RX 6000 or newer) is required to run the game at all. You cannot fully switch RT off, but you can tune how expensive it is:

• RT Reflections is the single biggest lever. Ray tracing can cost up to ~52% of your frame rate, and reflections are the most expensive part. Dropping reflections to Low — or off where the option exists — gives the largest FPS gain with the smallest visual hit during fast combat.
• Keep base RT lighting on. The game’s look depends on it, and lowering reflections already recovers most of the cost.

The heaviest non-RT settings

After ray tracing, two settings dominate:

• Volumetric Fog / Volumetric Lighting → Medium. This is the second-biggest cost. Medium keeps the atmosphere while recovering meaningful frames.
• Shadow Quality → Medium–High. Worth up to ~15% FPS; Medium-to-High looks nearly identical in motion.
• Effect Quality → Medium–High. Worth up to ~14% FPS; drop it a notch if you need more headroom during heavy encounters.

Everything else on this engine is cheap — leave the remaining quality options High.

VRAM and Texture Pool Size

DOOM: The Dark Ages is VRAM-hungry. It regularly exceeds 8 GB even at native 1080p, needs about 6 GB minimum at 1080p and ~10 GB at 4K to avoid texture-streaming stutter, and with path tracing plus frame generation at 4K peak usage can approach 20 GB.

• Match Texture Pool Size to your card. Keep it as high as your VRAM allows — that is where the game’s visual identity lives — but drop it a notch if you see texture pop-in or stutter that worsens over time.
• 8 GB GPUs: stay at 1080p/1440p, keep the texture pool moderate, and lean on upscaling.
• Run XMP/EXPO so system RAM feeds the streamer at full speed.
• Install on an SSD — NVMe ideal — to keep asset streaming smooth (NVMe vs SATA for gaming).

Upscaling and path tracing

DOOM: The Dark Ages ships with DLSS (NVIDIA) and FSR (AMD). Set upscaling to Quality — it is the single biggest “free” frame boost and offsets the VRAM load, so enable it before lowering any quality setting. See DLSS vs FSR vs XeSS to pick the right one.

Path Tracing was added as a high-end option. It is a stunning upgrade but an enormous cost — leave it off on anything below an RTX 4080-class card and spend the frames on a steadier refresh rate instead. Frame Generation (RTX 40-series / RX 7000-series) is best used on an already-stable base; it adds a little latency, as covered in frame generation input lag explained. Keep NVIDIA Reflex On to hold input lag down while frame gen is active.

Cap your frame rate and finish Windows-side

Once settings are dialed in, cap your FPS to a value your PC holds steadily so frame times stay flat — see how to cap your FPS correctly and best FPS cap for low latency. Then:

• Update your GPU driver or clean-install with DDU when upgrading.
• Disable VBS for a measurable FPS bump.
• Set a high-performance power plan and check Game Mode.
• Show an FPS overlay to verify each change.

Next steps

With graphics optimized, the final gains are in responsiveness — critical for a fast shooter. Lower system input lag with the timer resolution guide and the input delay guide, and confirm NVIDIA low latency mode is set correctly for the tightest aim.
