Say hello to AMD FidelityFX Variable Shading, FidelityFX Denoiser, and FidelityFX Parallel Sort

• November 24, 2020

Launched last year, our powerful AMD FidelityFX effects are rapidly gaining critical acclaim from games developers – you can now find FidelityFX in over 35 titles and rising. 

To accompany the recent launch of the AMD Radeon™ RX 6000 Series graphics cards, we’re releasing three new AMD FidelityFX effects to our existing five, to extend our open-source image quality toolkit even further. 

So without further ado, introducing:

• • AMD FidelityFX Variable Shading.
  • AMD FidelityFX Parallel Sort.
  • AMD FidelityFX Denoiser.

AMD FidelityFX Variable Shading provides an open source header implementation to easily integrate DirectX®12 Ultimate Variable Rate (VRS) Shading into your game. The effect works by analyzing luminance variance in the previous frame and uses motion vectors to generate a shading rate image.

AMD FidelityFX Parallel Sort also provides an open source header implementation, this time to easily integrate a highly optimized compute-based radix sort into your game.

AMD FidelityFX Denoiser includes a spatio-temporal denoiser optimized for reflection denoising. This reflection denoiser was originally a part of FidelityFX Stochastic Screen Space Reflections (SSSR) but has now been extracted to its own library.

We’ve not just been making new effects, we’ve also been hard at work on existing ones too!

AMD FidelityFX Stochastic Screen Space Reflections (SSSR) uses your rendered frame to create brilliant reflections. For v1.3, we’ve extracted the essential parts of the library to one HLSL header file to ease integration.

Don’t forget our other FidelityFX effects
