  "summary": "Modders have significantly improved the performance of FSR 4 on AMD’s BC-250 mining APU, reducing render times by nearly half. By creating a portable FidelityFX DLL, the processing time for upscaling 1440p content has been cut from 11.51 ms to 5.92 ms. This improvement is achieved through optimized handling of machine-learning and low-precision integer operations, which were previously executed inefficiently on the older RDNA 2 hardware. The new implementation maintains the same image quality while improving performance, making it a valuable enhancement for Linux gamers using the BC-250.",
