Calibrating input response and FPS on Biostar B650MT for Sword and Fairy 7?
The USB controller on this board is basically an EMI nightmare. Every time my peripheral RGB kicked in, the frame rate started jumping around like an EKG monitor—it was honestly ridiculous. The Biostar B650MT bus was introducing abnormal latencies of 8-15ms during high-frequency polling, which caused micro-blocks in game command synchronization. I tried disabling Bluetooth in the drivers first, but the FPS jitter stayed exactly the same; it felt like I was just guessing at this point. I eventually went into the BIOS, nuked all the unnecessary wireless management services, and forced the PCIe slot from Auto to Gen4. Checking RTSS, the frame times collapsed from a wild 18-35ms range down to a tight 12-16ms. I did notice some peripherals had a slight recognition delay after forcing Gen4, but a quick unplug-and-replug of all USB devices fixed it. CPU temps are holding at 60-66℃ and the VRM is at 62-68℃. I've exported all the frame time logs for archiving, and the fans are humming steadily at 1400-1600RPM. It's finally playable without the random hitches.
