How to fix Kioxia Exceria Pro throughput issues in CP2077?
Driving through Night City felt like a slideshow with massive screen tearing, and my frame times were jumping all over the place from 18-55ms. It totally killed the immersion. I dug into the logs and found the Kioxia Exceria Pro was glitching between PCIe 3.0 and 4.0 under heavy load, causing throughput to fluctuate between 3.5GB/s and 7.2GB/s. I tried enabling low-latency mode in the drivers, but while the mouse felt snappier, the frame drops stayed—it was just a band-aid on a bullet wound. I eventually went into the BIOS, forced the M.2 slot to Gen4 instead of Auto, and flashed the latest firmware. RTSS confirmed the frame intervals tightened to 14-18ms, and the smoothness is night and day. Interestingly, my boot time slowed by 2 seconds after forcing Gen4, which I only fixed by disabling Windows Fast Startup. Drive temps are stable at 55-62℃ with fans at 1500 RPM. After three hours of testing, the I/O bottleneck is dead, and memory temps are holding at 58-63℃.
