How to fix the stuttering on Fanxiang S910PRO in Metro Exodus?
Loading those high-fidelity ray-tracing scenes was a nightmare; the Fanxiang S910PRO read/write speeds were jumping wildly between 10-12GB/s, causing these annoying micro-stutters. HWiNFO showed the cache controller spiking from 55℃ to 88℃ in seconds, triggering a brutal thermal throttle. I tried cranking up the case fans, but that only dropped the temp by 3℃—completely useless against PCIe 5.0 heat. I eventually went into Power Options and set the disk state to Maximum Performance, killing all Link State Power Management. Surprisingly, that didn't fully fix it until I manually flashed the latest chipset drivers from the motherboard site. Only then did the curve flatten out, with the heatsink sitting at 66-72℃ under positive pressure. After checking IOPS, random read latency dropped from 14-26ms down to a rock steady 5-8ms, and frame times finally stabilized at 5.1-6.4ms.
