Modders halve FSR 4 render times on AMD BC-250 APU

By PulseAugur Editorial · [1 sources] ·

Modders have significantly improved the performance of AMD's FidelityFX Super Resolution 4 (FSR 4) upscaling technology on the BC-250 mining APU, which is derived from PlayStation 5 hardware. By porting optimizations from a custom Mesa modification into a portable FidelityFX DLL, they reduced the rendering time for FSR 4 at 1440p from 11.51 ms to 5.92 ms, and at 4K from 25.72 ms to 12.08 ms. This optimization achieves byte-identical image quality to the original shaders, suggesting a more efficient execution of the same workload. AI

IMPACT Improved efficiency for AI-driven upscaling techniques on older hardware, potentially enabling wider adoption.

RANK_REASON This is a community optimization of an existing technology (FSR 4) on specific hardware (BC-250 APU), not a release from a frontier lab or a significant industry-wide event.
