Why is Tekken 8 feeling sluggish on the Onda B760ITX-B4?
When pulling off high-frequency combos, I noticed a micro-stutter in my character's execution that is absolutely lethal in high-rank matches. The USB controller on the Onda B760ITX-B4 was a nightmare, with interrupt requests swinging wildly between 12-35ms while hitting a 1000Hz polling rate, causing the command queue to just pile up. I tried toggling Game Mode in Windows, but that software-level tweak did nothing for the underlying bus conflict, which left me feeling completely stuck. I eventually dove into Device Manager, killed all power management options for the USB Root Hubs, and used a low-level utility to bump the interrupt priority to the highest level. On my latency analyzer, the response time collapsed from 22-40ms down to a rock steady 4-7ms. My inputs finally feel instant. Interestingly, the first time I pushed the priority, I got some nasty audio popping until I dropped the sample rate from 192kHz to 48kHz. VRM temps stayed around 52-58℃ and USB ports hit 38-42℃. Verified with a latency tester—the lag is gone and settings are locked in.
