Best Total War: Warhammer III settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), Total War: Warhammer III runs at roughly 86 FPS at 4K with our optimized settings — up from about 87FPS 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 Total War: Warhammer III is a demanding, graphically heavy game. Paired with the Intel Core i9-14900K, it runs well at 4K — about 86 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 152 FPS at 1440p, dropping to roughly 86 FPS at 4K. Its 24GB of VRAM is plenty for Total War: Warhammer III, 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.

💡 Total War: Warhammer III: Massive battles are very CPU-heavy; lower Unit Detail first.
Recommended settings
Upscaling — DLSSOff
Total War: Warhammer III supports DLSS and FSR. A free FPS boost - but huge battles are CPU-bound, so don't expect it to fix the frame drops with thousands of units.
Texture QualityUltra-1% FPS
Surface sharpness on units and terrain - cheap on FPS if it fits your VRAM.
Unit DetailHighbaseline
Detail and count on individual soldiers - the heaviest setting in big battles (and it leans on the CPU). High is the value pick over Ultra.
Shadow QualityHighbaseline
Shadow resolution and range across the battlefield. High looks nearly identical to Ultra.
Grass QualityMediumbaseline
Battlefield grass density. A real cost in big fights - drop it for an easy win.
Tree DetailHighbaseline
Tree density and detail on the battlefield. Medium is a safe trim in forested maps.
VFX DetailHighbaseline
Spells, fire and combat effects - heavy in magic-heavy battles. High keeps things smooth.
Water QualityMediumbaseline
Reflections and detail on water. Medium is plenty.
