Why is my Fanxiang S910PRO 2TB stuttering in Ark 2?
It was a complete nightmare trying to load a giant island with thousands of entities when the screen just froze for about 0.4 seconds. I was baffled because this is a top-tier PCIe 5.0 drive. Checking the backend, I noticed that while the Fanxiang S910PRO 2TB has insane throughput, the I/O queue depth was jumping wildly between 32 and 64 during random small file reads, causing latency spikes from 12ms to 28ms. I first tried killing all background services in Windows, but that barely freed any RAM and did absolutely nothing for the disk bottleneck—it was too surface-level. I eventually dove into the advanced driver settings and forced the NVMe queue depth to 128, while simultaneously disabling PCIe Link State Power Management in the BIOS. Suddenly, the read latency tightened up to 6-11ms and the asset streaming became buttery smooth. I did run into a weird issue where the system had a slight recognition delay during cold boots right after the tweak, but updating the motherboard chipset drivers fixed it. Temperatures stayed steady between 48-56℃. Verified the scheduling parameters are locked in via storage analysis tools.
