Why does Monster Hunter Wilds keep freezing up during map transitions on my Western Digital SN850X 1TB?

Whenever I hit those massive Wilds ecosystems, the loading bar just hangs at 85%, and that micro-stutter is a total nightmare during a hunt. The WD SN850X 1TB's dynamic SLC cache tends to saturate during heavy bursts, causing random read speeds to tank from 700 MB/s down to a shaky 400-550 MB/s. I initially tried locking my virtual memory to a fixed size, but that was a complete waste of time—it didn't fix the stutters and actually caused the game to crash when RAM usage spiked, which left me pretty frustrated. I eventually pivoted to installing the latest NVMe drivers, killed the power-saving mode in Device Manager, and forced the write cache flush. After running CrystalDiskMark, I saw 4K random read latency drop from 65ms to a much tighter 38-42ms, and map transitions finally felt fluid. Funnily enough, right after the driver update, the drive started disappearing during idle; I had to disable PCIe Link State Power Management in the BIOS to stop the disappearing act. Temps are now sitting steady between 48-55℃ with the heatsink doing its job. Using a profiler, the read curve is finally flat, and frame times are locked in at 5.1-6.4ms on Win11 24H2.
