There’s a new GPUOpen website, and with its redesign comes four new open-source FidelityFX effects to improve the AMD Radeon gaming experience. Stand by for acronyms (or initialisms): we’ve got CACAO, SSSR, LPM, and SPD—many of which have been optimised for the RDNA architecture.

The four new technologies are:

  • FidelityFX Screen Space Reflections: Implementation of Stochastic Screen Space Reflections (SSSR) delivers high-quality reflections with minimal overhead via an optimized compute shader and RDNA architecture-optimized denoising.
  • FidelityFX Ambient Occlusion: RDNA architecture-optimized Combined Adaptive Compute Ambient Occlusion (CACAO) effect dynamically and efficiently helps improve the appearance of objects based their exposure to ambient light.
  • FidelityFX HDR Mapper: Optimised for use with AMD FreeSync Premium Pro displays, the Luminance Preserving Mapper (LPM) delivers superior HDR and wide color gamut content for games.
  • FidelityFX Downsampler: Optimized for RDNA architecture, AMD’s compute shader-based Single Pass Downsampler (SPD) generates texture MIP levels using asynchronous compute for optimal performance.
