Upscale
Upscale (DLSS/FSR2/XeSS) renders the game at a lower resolution and reconstructs it to a higher one, increasing FPS.
TAA
DLSS anti-aliasing uses temporal upscaling with resolution reconstruction and aggressive edge smoothing. It blends multiple frames for a sharper, smoother image without large detail loss.
CAS
CAS (Contrast Adaptive Sharpening) is a sharpening filter that boosts contrast on object edges for a crisper image, without amplifying noise or flat-surface artifacts.
PBR
PBR (Physically Based Rendering) is a rendering approach based on physical light/material interaction. It produces realistic surfaces (metal, wood, skin, etc.) and maintains consistent look across different light sources.
Chromatic Aberration
Chromatic aberration slightly splits colors at object edges, adding subtle “color outlines” to mimic lens distortion for extra realism.
Vignette
Vignette darkens the image edges toward the corners, focusing attention on the center and adding a cinematic feel.
Saturation
Saturation controls color intensity: high saturation makes colors bright and punchy, low saturation makes them pale or nearly gray.
Reflections
Water reflections simulate a mirror of the environment on the surface, accounting for ripples, waves, and transparency to keep scenes believable.
Ambient Occlusion
Ambient Occlusion darkens creases and corners where light is occluded.
GTAO
GTAO is more accurate and physically grounded, modeling light distribution for softer, more realistic small-scale shadows.
SSAO
SSAO is a fast screen-space method; it approximates darkening from depth/normals and can show minor artifacts.
Hashed Alpha Test
Hashed Alpha Test discards transparent pixels using (pseudo)random hashing to smooth edges and reduce jaggies on alpha textures, especially vegetation and meshes.
Snow Mask
Snow Mask dynamically lays snow on outdoor objects (static and dynamic) based on their normal maps.
