Modders halve FSR 4 render times on AMD’s PS5-derived BC-250 mining APU — portable FidelityFX DLL cuts 1440p upscaling time from 11.51 ms to 5.92 ms
At 4K, processing time reportedly dropped from 25.72 ms to 12.08 ms, while 1080p fell from 7.13 ms to 3.93 ms. FSR 4 relies heavily on machine-learning workloads and accelerated low-precision integer operations that are far better suited to newer AMD architectures. On the BC-250, those operations have to be handled through alternative instruction paths.Latest Videos FromTom's HardwareWatch full video here: Earlier community work tackled the problem in Mesa, optimizing the INT8 dot-product operations used by FSR 4.
