How to fix data sync lag on Samsung 9100 PRO 8TB?
Turning quickly in the heat of battle made the building textures look like they were being ripped apart—it was a total nightmare for immersion. The Samsung 9100 PRO 8TB has monstrous PCIe 5.0 bandwidth, but at 10-12GB/s throughput, it hit a microsecond sync drift with the CPU, causing the VRAM buffer to swing wildly between 14.2-15.8GB. I tried dropping the graphics to Medium, which gained me about 12 FPS, but the flickering stayed; that was just a band-aid solution that ignored the real problem. I eventually dove into the BIOS, forced the PCIe link speed to Gen5 instead of 'Auto', and enabled Re-Size BAR. In RTSS, the frame time spikes of 11-24ms smoothed out to a tight 8-12ms, and the tearing vanished. I actually struggled to boot the first time I locked Gen5 until I updated the motherboard BIOS. The SSD hovered between 62-68℃ with the active cooler humming at 2800 RPM. System logs now show zero transfer errors, and the link is finally stable.
