Optimizing Great Wall GW3300 512GB load speeds in Metro?
Every time I entered a tunnel, the loading screen felt like a personal insult. The wait was just agonizing and completely broke the immersion. While the Great Wall GW3300 claims decent speeds, the addressing latency on the 512GB partition was bouncing between 120-145ns, creating a total gap in resource scheduling. I tried running a disk defrag at first, which was a complete waste of time for an NVMe drive and just ate into the write endurance—totally ridiculous. I ended up wiping the OEM drivers and switching to the generic NVMe 1.4 protocol driver, then enabled Re-size BAR in the BIOS. In CrystalDiskMark, sequential reads climbed from 3200MB/s to 3400-3600MB/s, and scene load times dropped from 12 seconds to just 6. I did notice that Re-size BAR made my boot time 2 seconds slower with the old drivers, but a chipset update fixed that. The drive stays at 52-58℃ with fans at 1500 RPM. Exported all latency logs to verify the fix. Data export successful.
