What's new in the AMD FidelityFX™ SDK 1.1.4?

The AMD FidelityFX SDK 1.1.4 is a patch release that includes additions to API and fixes for issues discovered with FSR 3.1.0 to 3.1.3.

  • Exposed 4 new tunings to reduce FSR upscaler ghosting in newly disoccludded pixels or highly reactive pixels.
  • Changed the default value of fMinDisocclusionAccumulation to -0.333 (from equivalent of 0.333 in FSR3.1.3) to reduce disocclusion ghosting.
  • Added ffxQueryGetProviderVersion to get version info from created ffx-api context.
  • Exposed ffxDispatchDescFrameGenerationPrepareCameraInfo as a linked struct. It is a required input to FSR 3.1.4 and onwards for best quality.
  • Added frame generation debug checker support.
  • Dropped unused interpolation command lists if frame generation callback fails, to fix infinite wait at swapchain destruction.
  • General fixes to Vulkan Frame Interpolation Swapchain.
  • General framework fixes and updates.
  • Frame pacing debug line added to Vulkan.
  • Added new FFX error when create frame interpolation swapchain results in E_ACCESSDENIED in DX12 due to overlay or capture software.
  • Enabled support for frame interpolation swapchain on Windows 10 1909 and potentially earlier versions.
  • Fixed flipped disocclusion factor from previous and current backbuffer.
  • Fixed HDR mode issues in Cauldron sample.
  • Fixed MSVC C compile errors including ffx-api.
