A Breakthrough Gaming Architecture
RDNA2 ArchitectureAMD RDNA™ 2 architecture is the foundation of next-generation gaming PCs and consoles. It is the bedrock of the upcoming revolution in PC gaming graphics and cloud gaming. AMD RDNA™ 2 elevates and unifies visual effects and gameplay across multi- gaming platforms, like no other graphics architecture before.
AMD FidelityFX
Contrast Adaptive SharpeningOFF
Contrast Adaptive SharpeningON
Bring Out All The DetailContrast 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.
Shading Rate OverlayOFF
Shading Rate OverlayON
Get Performance with QualityUsing RDNA2 architecture and variable rate shading allows fidelityFX to analyse luminance and motion of frames to help optimise rending to ensure you also get optimal performance without reducing image quality.
Ambient OcclusionOFF
