Best Doom Eternal settings for the RTX 4080 Laptop (2026)

On a RTX 4080 Laptop (paired with a balanced AMD Ryzen 9 5950X-class CPU), Doom Eternal runs at roughly 122 FPS at 1440p with our optimized settings — up from about 123FPS with everything maxed. Here's the configuration and what each setting costs.

The RTX 4080 Laptop is a strong 1440p graphics card with 12GB of VRAM, and Doom Eternal is a moderately demanding game. Paired with the AMD Ryzen 9 5950X, it flies at 1440p — about 122 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 203 FPS at 1080p and 122 FPS at 1440p, dropping to roughly 69 FPS at 4K. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

Recommended settings
Upscaling — DLSSOff
Doom Eternal (id Tech 7) added DLSS in a later update. The engine is famously well-optimised, so this is mostly a 4K / weaker-GPU lever.
Texture Pool SizeNightmare-1% FPS
How much VRAM is reserved for textures. Ultra is safe on 8GB; Nightmare wants 10GB+.
Lights QualityUltrabaseline
Number and quality of dynamic lights — the heaviest GPU setting in busy arenas. High/Ultra looks great without the Nightmare cost.
Shadows QualityUltrabaseline
Shadow resolution and filtering. Ultra is a clean step below Nightmare with barely a visual difference mid-fight.
Reflections QualityHighbaseline
Screen-space reflections on metal and blood. High is plenty during the carnage.
Volumetric QualityHighbaseline
Fog, smoke and god-rays. High keeps the mood while trimming a busy scene.
ParticlesHighbaseline
Gore, fire and explosion effects — lowering smooths the heaviest Slayer Gate fights.
