AMD is set to present FidelityFX SDK, “A consolidation of all the great FidelityFX technologies available on GPUOpen into a sleek, easy-to-use SDK,” at GDC 2023. No official confirmation exists, but we’re certain that Team Red will unveil its FSR 3.0 upscaling technology at the event. AMD has struggled to compete with the RTX 40 series lineup since it launched last year.
The Radeon RX 7900 series offers decent raster performance but falls short in ray tracing, a deficit that is magnified by the use of next-gen upscaling technology DLSS 3 on Team Green’s end. NVIDIA’s DLSS 3 upscaler reconstructs entire frames using temporal data obtained from in-game motion vectors and optical flow data:
AMD uses “Fluid Motion Frames” as the basis of FSR 3.0. We don’t know what FMM is, but if history is any guide, then it won’t be much different from optical motion flow.
We don’t expect FSR 3.0 to leverage hardware acceleration, but there’s a chance that AMD might go with a low-precision instruction set like DP4a that doesn’t require specialized XMX or Tensor cores. Since we’re looking at a frame generation technology, performance should technically double or more, alleviating the gulf between RDNA 3 and Ada Lovelace in ray-traced titles.
AMD is set to present “The FidelityFX SDK” on the 23rd of March between 1000 and 1100 in Room 3001 of the West Hall at GDC 2023.
