Updated effects

AMD FidelityFX Frameinterpolation Swapchain 1.1.3

AMD FidelityFX Super Resolution 3.1.4 (FSR 3.1.4)

Reduces upscaler disocclusion ghosting by setting default fMinDisocclusionAccumulation to -0.333 from FSR 3.1.3 equivalent default of 0.333.
In small fraction of games, fMinDisocclusionAccumulation of -0.333 results in more white pixel flickering in swaying grass vs 0.333.


AMD FidelityFX Super Resolution (FSR) API

  • Minor non-API breaking additions:
    ffxConfigureDescUpscaleKeyValue to tune upscaler ghosting.
    ffxQueryGetProviderVersion to get version info from created ffx-api context.
    ffxDispatchDescFrameGenerationPrepareCameraInfo is a required input to FSR 3.1.4 and onwards for best quality.
    FFX_FRAMEGENERATION_ENABLE_DEBUG_CHECKING at context creation to enable frame generation debug checker.
    ffxConfigureDescGlobalDebug1 to assign fpMessage callback for debug checker to output textual messages. If fpMessage is nullptr, debug checker will output messages to debugger TTY.
