My Fanxiang S790 4TB has wild response fluctuations in Nioh 2 co-op, should I lock the PCIe link?

Fighting swarms of demons is awesome until you hit those random micro-stutters. The Fanxiang S790 4TB has an overly aggressive I/O scheduling policy for fragmented assets, with response times jumping between 1ms and 25ms, causing frame times to spike from 12ms to 35ms. I tried killing all background apps in Windows, but while CPU usage dropped, the I/O jitter stayed—just a waste of time. I went into the BIOS, disabled PCIe Link State Power Management, and forced the drive into High Performance mode. In RTSS, the frame time variance dropped from 10-30ms down to a tight 13-16ms. The game feels way smoother now. I did notice the idle temp went up by 4℃ after disabling power management, but I fixed that by tweaking my case airflow. Drive temps are now steady at 52-58℃ and the motherboard is at 60-66℃. Monitoring confirms the scheduling mode is active and holding steady.
