Full FSR 2.2 pipeline with depth-based motion vector reprojection, temporal accumulation with YCoCg neighborhood clamping, and RCAS contrast-adaptive sharpening. Architecture (designed for FSR 3.x frame generation readiness): - Camera: Halton(2,3) sub-pixel jitter with unjittered projection stored separately for motion vector computation - Motion vectors: compute shader reconstructs world position from depth + inverse VP, reprojects with previous frame's VP - Temporal accumulation: compute shader blends 5-10% current frame with 90-95% clamped history, adaptive blend for disocclusion - History: ping-pong R16G16B16A16 buffers at display resolution - Sharpening: RCAS fragment pass with contrast-adaptive weights Integration: - FSR2 replaces both FSR1 and MSAA when enabled - Scene renders to internal resolution framebuffer (no MSAA) - Compute passes run between scene and swapchain render passes - Camera cut detection resets history on teleport - Quality presets shared with FSR1 (0.50-0.77 scale factors) - UI: "Upscaling" combo with Off/FSR 1.0/FSR 2.2 options |
