Best World War Z settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), World War Z runs at roughly 173 FPS at 4K with our optimized settings — up from about 174FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 4090 is a flagship 4K-class graphics card with 24GB of VRAM, and World War Z is a relatively light game to run. Paired with the Intel Core i9-14900K, it flies at 4K — about 173 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 263 FPS at 1080p and 263 FPS at 1440p, dropping to roughly 173 FPS at 4K. Its 24GB of VRAM is plenty for World War Z, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

World War Z (Saber's Swarm engine) is extremely well-optimised and supports FSR 2.2 — the main GPU lever, though most PCs run this game very high without it.
Texture QualityUltra-1% FPS
Surface sharpness — nearly free with 6GB+ VRAM.
DetailsHighbaseline
Overall world/geometry detail and draw distance. High is a safe trim from Ultra.
Shadow QualityHighbaseline
Shadow resolution and range. High is a clean step below Ultra.
Lighting QualityHighbaseline

Effects QualityHighbaseline
The signature zombie-swarm effects — heaviest when hundreds pile up. High holds up in the big set-pieces.
