Future FSR3 support

1

Hi Team, any plan for UE4 plugin support like 4.27, and any schedule for native Vulkan support?

Hi team, I just wonder if we can do code contributions to FSR3 since now it's an open-soureced project?

I find this formula to calculate the luminance of scRGB (R16G16B16A16F HDR) colors a bit confusing. In DirectX 11 and 12, scRGB swapchain buffers have a luminance of 80 nits...

Bug. I haven't checked FSR code exhaustively (e.g. upscaling) but I do know this applies to frame interpolation at the minimum. Passing the flag `FFX_XXXXX_ENABLE_TEXTURE1D_USAGE` to [ffxFsr3ContextCreate](https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/a0632abf1350bb64c098573d84c42f053f053a6e/sdk/src/components/fsr3/ffx_fsr3.cpp#L139) or [ffxFrameInterpolationContextCreate](https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/a0632abf1350bb64c098573d84c42f053f053a6e/sdk/src/components/frameinterpolation/ffx_frameinterpolation.cpp#L490) results...

Remove GPU include file in the public header

1

Might be beneficial to remove this line, to reduce dependency on `gpu` headers https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/a0632abf1350bb64c098573d84c42f053f053a6e/sdk/include/FidelityFX/host/ffx_fsr3upscaler.h#L27

Upscaler itself has something to do with frameinterpolation?

1

Looks like the upscaler is simply FSR 2: https://gpuopen.com/manuals/fidelityfx_sdk/fidelityfx_sdk-page_techniques_super-resolution-upscaler/ FSR 3 has the additional frameinterpolation: https://gpuopen.com/manuals/fidelityfx_sdk/fidelityfx_sdk-page_techniques_super-resolution-interpolation/ https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/release-FSR3-3.0.3/sdk/src/components/fsr3upscaler/ffx_fsr3upscaler.cpp#L998 While this upscaler code mention "need to clear here since we need the...

Optical flow scheduleDispatch unused parameter.

1

Hello, pipelineName in scheduleDispatch is not used. https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/a0632abf1350bb64c098573d84c42f053f053a6e/sdk/src/components/opticalflow/ffx_opticalflow.cpp#L465 The worst part is that it's a std::string so it allocates memory at runtime even when passing a static name. I haven't...

Should "FidelityFX Native SDK.sln" contains a "Backends" folder?

1

Like "FidelityFX SDK.sln" does.
