Alpha Piscium v1.8.3

Highlight

• Major performance optimizations on rasterization pass
• Config profiles for different quality/performance tiers

New

• Added config profiles for different quality/performance tiers
• Added Assume NV GPU option for NVIDIA-specific optimizations
• Separated SSS sample count from blocker search count for better control

Improvement

• Optimized gbuffer pass viewZ attribute by computing from gl_FragCoord.w
• Optimized terrain draw normal vertex attributes
• Optimized shadow pass attributes
• Optimized denoiser reproject register usage
• Optimized denoiser stabilization pass occupancy
• Removed some vertex attributes for passes that don't need them
• Optimized SST register usage and ray sorting key layout
• Optimized GI5 storing handle register usage
• DenoiseBlur FP16 optimization
• ReSTIR temporal reuse math simplification
• Early return branching optimization
• Updated TAA filter kernel for lower quality profile
• Reduced TAA motion blur
• Tone mapping tweak
• Moved cloud clear from GIReproject to ShadowSample pass to balance VRAM loads
• Moved fast history storing to history fix pass to balance VRAM loads
• Emissive color curve now performed in input color space for better consistency
• Removed spatial reuse feedback due to firefly artifacts

Fix

• Fixed hit distance on disocclusion
• Fixed backward analysis distance check
• Fixed GBufferTranslucent material id reading
• Fixed RTWSM forward analysis writing position
• Fixed extra water tinting
• Fixed history length diffusion killing disocclusion fix

Misc

• Removed unused shadow specular output and associated references
• Removed reservoir age reset
