My game keeps hanging at 90% loading on the Fanxiang S910PRO in Dead Space 2. How do I stop this lag?

Every time I entered a new horror zone, the loading bar would just die at 90%. It completely killed the pacing and honestly made me anxious as hell. The Fanxiang S910PRO's PCIe 5.0 link was hitting 120-280ms handshake delays on my board, causing the engine to time out and deadlock. I tried disabling the page file, which was a complete waste of time and actually made the freezes happen more often. The real fix was updating the BIOS to the latest version and manually forcing the M.2 slot to Gen5 instead of 'Auto'. In CrystalDiskMark stress tests, reads stayed locked at 10000-12000MB/s, and the hangs disappeared. I noticed my cold boot time increased by about 3 seconds after the change, but disabling 'Fast Boot' in BIOS fixed that. Drive temps are hovering between 58-68℃. MemTest86 confirms zero data errors, and the input response finally feels tight and snappy.
