How to reduce controller input delay on Soyo SY-A320D4+?
Having my combos freeze at the worst possible moment was infuriating; it felt like the hardware was trolling my skill. The USB bus on the Soyo SY-A320D4+ was having scheduling conflicts with my high-polling rate peripherals, adding a nasty 15-25ms of lag. I tried switching to a USB 3.0 port, but ironically, the lag got worse by another 5ms—just ridiculous. I decided to strip things down in the BIOS, disabling all the unnecessary integrated audio enhancements and setting the USB port mode to 'Legacy' priority. Using a latency tester, I saw the response time plummet from 22ms to a crisp 6-8ms. My inputs finally feel instant. The only downside was a slight dip in audio quality after disabling the enhancements, which I eventually fixed with a third-party driver. Board temps are 38-45℃ idle and 52-58℃ under load. I exported the latency logs, and the difference is night and day.
