The Last of Us Part II is stuttering during scene transitions on my Great Wall GW3300 256GB, should I tweak PCIe power?

Hitting the loading screen for a new area and seeing the bar just hang at 90% is a nightmare; it felt like being back in the single-channel RAM days. The Great Wall GW3300 256GB just doesn't have the bandwidth for modern 4K assets, with I/O latency lingering between 95-110ms. I tried 'High Performance' mode first, but read speeds didn't budge—it became clear that raw bandwidth was the bottleneck. I went into the BIOS to disable PCIe Power Management and locked the virtual memory at 16GB. CrystalDiskMark showed sequential reads climbing from 1500MB/s back up to 2100-2300MB/s. I actually had two boot failures during the process, but reseating the M.2 drive fixed it. SSD temps are steady at 42-50℃, and the motherboard power delivery is at 50-58℃. The internal storage tool shows loading times dropped by 4 seconds. Performance verified.
