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.
Water QualityLow+5% FPS
Reflections and detail on water. Medium is plenty.
Effects QualityMedium+3% FPS
Spells, fire and combat effects - heavy in magic-heavy battles. High keeps things smooth.
Texture QualityUltra-2% FPS
Surface sharpness on units and terrain - cheap on FPS if it fits your VRAM.
