v1.1

Release Notes

This release of the FidelityFX Denoiser adds a new denoiser specialised for ray traced shadow rendering.

• New high-performance spatio-temporal denoiser, specialized for shadow denoising.
• Tile classifier to skip work on areas without spatial variance in the shadow mask.
• Increased contribution of spatial filters on low temporal sample counts.
• Analysis of the local pixel neighborhood to counter ghosting artifacts.

FidelityFX Denoiser v1.0

Release Notes

This first release includes a high performance spatio-temporal denoiser specialized for reflection denoising. The preferred use case of this denoiser is within applications requiring denoised radiance values generated by a stochastic reflection implementation.

• High performance spatio-temporal denoiser, specialized for reflection denoising.
• Tile Classifier to skip non reflective areas.
• Variable Rate Traversal: From full rate for mirror reflections down to quarter rate for glossy reflections.
• Temporal Variance Guided Tracing.

Includes

• Classifier pass for reflection rays and denoiser tiles.
• Spatial filter pass.
• Temporal reprojection pass.
• Gaussian blur.
