Why is my Fanxiang S910PRO 2TB dropping frames in Horizon Zero Dawn?
Just as a massive machine appeared on screen, my frame rate tanked to 30 FPS. That kind of performance drop turns excitement into pure frustration instantly. Looking at the specs, the Fanxiang S910PRO 2TB's PCIe 5.0 link was hitting sync clock deviations during high throughput, causing 12-20ms of command latency. I tried enabling DLSS Performance mode first, but the edges got all blurry and smudgy—totally unacceptable. I went into the BIOS, disabled PCIe Link State Power Management, and shifted the drive's power state from 'Maximum Performance' to 'Balanced'. In CPU-Z storage tests, the random read latency tightened from 85ns down to 62ns, and the in-game drops vanished. I did have a weird issue where my boot time increased by about 4 seconds after the change, but I fixed that by reconfiguring the Fast Boot settings. The drive now stays between 58-64℃, and the motherboard VRM is around 65-72℃. The in-game performance overlay confirms the temps are stable now.
