Why does my Onda 9D4-DVH motherboard cause frame drops and sluggish response during fast combat?

When pulling off high-frequency combos, I noticed a weird 'stickiness' when switching between covers, making precise parries an absolute nightmare. The Onda 9D4-DVH chipset was hitting irregular spikes of 12-18ms when processing high-frequency requests, causing a massive bottleneck in the instruction queue. I initially tried disabling all power-saving options in Windows, but that did nothing—actually, it made my mouse cursor skip slightly during fast movements, which was just confusing. I eventually dove into the BIOS Advanced Power Management and forced Global C-States OFF, then locked the PCIe link speed to Gen 3 instead of Auto. Using a latency analyzer, I saw the bus response time collapse from a messy 15.4-22.1ms down to a rock-steady 4.2-6.8ms. The controls felt crisp instantly. Interestingly, my idle power draw jumped by 15W after the tweak, but I managed to stabilize things by bumping the memory voltage to 1.35V. Motherboard temps stayed around 62-68℃ with fans humming at 1200-1400 RPM. Checking the hardware monitor, the frame generation time finally flattened out at 5.1-6.4ms.
