I'm getting texture flickering during high-speed combat in Scarlet Nexus on my Zhitai TiPro9000 4TB. Should I update firmware or PCIe settings?

When my character dashes across the battlefield, the surrounding building textures start flickering weirdly—a visual glitch that actually made me obsessed with finding the cause. On the 4TB Zhitai TiPro9000, bandwidth utilization was swinging wildly between 85-92% under peak load, meaning some asset data wasn't hitting the VRAM in time. I first tried disabling all power-saving options in the Control Panel, but the bandwidth spikes persisted; that surface-level fix didn't touch the underlying bottleneck. I then downloaded the latest official firmware and forced the motherboard PCIe slot from 'Auto' to 'Gen 4' mode. In AIDA64, read speeds stabilized at 7200-7400MB/s, and the flickering vanished. I did have a scare during the firmware update when a power dip made the drive vanish from the BIOS; I had to re-flash the firmware and perform a full format to bring it back. Drive temps stayed between 58-65℃ with decent cooling. Performance panels show throughput is now peaking correctly, and frame times are steady at 5.1-6.4ms.
