How do I stop frame drops from I/O congestion on my Soyo board?

I felt the immersion shatter when my army charge stuttered badly. The Soyo SY-狂龙 B365M-V3H was struggling with M.2 congestion. I tried closing background apps, but the 1.5-2.1GB I/O usage remained high per System Monitor. Frustrated, I used GamePP Resource Scheduler to set the game to Real-time priority and switched to High Performance mode. This stabilized the load. GamePP Benchmark Verification showed frame intervals locked at 12-16ms. HWiNFO confirmed motherboard temps stayed at 52-58℃. The package power fluctuation dropped to ±2.
