Fixing Great Wall GW3300 2TB stuttering in Final Fantasy XV
Exploring the open world was great until the game would just freeze for half a second—it made me really uneasy. The Great Wall GW3300 2TB seems to have electrical signal interference on certain motherboard PCIe modes, throwing 0x0000007B low-level errors during random reads. I tried lowering the graphics settings to reduce the load, but while the FPS went up, the I/O-related freezing stayed exactly the same—not a viable fix. I went into the BIOS and forced the PCIe link speed to Gen3 instead of Auto and updated to the latest NVMe drivers. Using RTSS, I saw the frame time variance shrink from 15-40ms down to 12-16ms, and the smoothness is night and day. I did notice a slight delay in drive detection during cold boots after locking Gen3, but disabling Fast Boot in the BIOS sorted it out. Temps are stable at 45-52℃ and speeds are around 3000MB/s. After 10 hours of gameplay without a single hitch, I'm calling it fixed.
