BRING OUT ALL THE DETAIL

Contrast Adaptive Sharpening (CAS) helps increase visual quality by enabling stunning visual sharpness with optional upscaling to restore detail lost after Temporal Anti-Aliasing (TAA) is applied. For games that support FidelityFX CAS, turning off Radeon™ Image Sharpening in Radeon™ Software to avoid over-sharpening is recommended.
