Best Project Zomboid settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), Project Zomboid runs at roughly 205 FPS at 4K with our optimized settings — up from about 205FPS 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 Project Zomboid is a relatively light game to run. Paired with the Intel Core i9-14900K, it flies at 4K — about 205 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 205 FPS at 1080p and 205 FPS at 1440p, dropping to roughly 205 FPS at 4K. Its 24GB of VRAM is plenty for Project Zomboid, so textures can stay maxed. Project Zomboid doesn't use upscaling, so the gains come from trimming the heaviest settings below.

Recommended settings
Lighting QualityHighbaseline
Quality of the dynamic lighting model. The main GPU-side setting in this 2D isometric game (which is otherwise almost entirely CPU-bound).
Lighting UpdatesNormalbaseline
How often dynamic lighting recalculates. Normal is fine; lower it on weak CPUs.
3D ModelsHighbaseline
Detail of 3D character, zombie and object models (with a "Show 3D Objects" toggle). Lower it for a cheap gain.
Environment ReflectionsOnbaseline
Reflections on wet ground and windows. Cheap to turn off.
Puddle QualityLowbaseline
Rain puddle detail. A small, safe saving.
Texture CompressionOnbaseline
Compresses textures to ease VRAM use — leave on unless you run the 2x texture pack. The game uses very little VRAM.

What are the best Project Zomboid settings for the NVIDIA RTX 4090?

Use a balanced preset, keep ray tracing off for maximum FPS, and ease the heaviest options like Lighting Quality and Lighting Updates down a notch. The full per-setting breakdown is above.

FPS figures are estimates from a generalized model (hardware tier × game load × per-setting weights), not live benchmarks — real performance varies by scene, drivers and game version.
