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
Modders have nearly halved FSR 4 processing time on AMD’s PS5-derived BC-250, using a portable FidelityFX DLL that cuts 1440p upscaling cost to 5.92 ms.
Modders have significantly reduced the processing time required for FSR 4 on AMD's BC-250, a PlayStation 5-derived crypto-mining board. The new implementation, which involves a portable FidelityFX DLL, cuts the upscaling time from 11.51 ms to 5.92 ms at 1440p resolution. This improvement, detailed in a VideoCardz post, builds upon earlier efforts to turn the AMD RSNA 2-powered board into a capable Linux gaming machine.
The optimizations, originally developed for Mesa, are now incorporated into a portable DLL, eliminating the need for a custom Mesa build. The performance gains are due to more efficient execution of machine-learning workloads and accelerated low-precision integer operations, rather than a reduction in image quality. At 4K resolution, the processing time drops from 25.72 ms to 12.08 ms, and at 1080p, it falls from 7.13 ms to 3.93 ms. Despite the BC-250's limitations, such as an aging CPU and limited memory, halving the upscaler's per-frame cost provides the board with more headroom for other tasks.
