Best Total War: Warhammer III settings for the AMD Radeon 660M (iGPU) (2026)

On a AMD Radeon 660M (iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Total War: Warhammer III runs at roughly 29 FPS at 1080p with our optimized settings — up from about 12FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD Radeon 660M (iGPU) is a entry-level graphics card with 2GB of VRAM, and Total War: Warhammer III is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 29 FPS with FrameCoach's optimized settings, a clear jump from roughly 12 FPS with everything on High.

Across resolutions you can expect around 29 FPS at 1080p and 17 FPS at 1440p, dropping to roughly 10 FPS at 4K. The biggest free win is FSR 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.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
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.
Unit DetailLow+14% FPS
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 QualityLow+10% FPS
Shadow resolution and range across the battlefield. High looks nearly identical to Ultra.
Grass QualityOff+8% FPS
Battlefield grass density. A real cost in big fights - drop it for an easy win.
VFX DetailLow+7% FPS
Spells, fire and combat effects - heavy in magic-heavy battles. High keeps things smooth.
Tree DetailLow+6% FPS
Tree density and detail on the battlefield. Medium is a safe trim in forested maps.
Water QualityLow+5% FPS
Reflections and detail on water. Medium is plenty.
Texture QualityUltra-1% FPS
Surface sharpness on units and terrain - cheap on FPS if it fits your VRAM.
