Fixing bus bandwidth on ASRock H310CM-ITX/ac for Silent Hill 2?

The foggy streets should have been atmospheric, but every time I turned the camera, there was this annoying 120ms trail that ruined the immersion. Looking at the logs, the PCIe link on the ASRock H310CM-ITX was struggling with massive texture streams, causing constant signal retransmissions that made the effective bandwidth oscillate violently between 4GB/s and 8GB/s. My first instinct was to blast the latest GPU drivers, but that just led to a crash on startup—a total frustration that forced me to look at the hardware level. I dove into the BIOS and forced the PCIe speed to Gen3 instead of 'Auto' and disabled all motherboard power-saving states. Using a latency tester, the end-to-end response time plummeted from 55-70ms to a crisp 22-28ms, and that 'sticky' feeling vanished. I did hit a snag where the SSD took forever to be recognized at boot after locking Gen3, but switching Windows to High Performance sorted it out. Chipset temps are now 45-52℃ and the GPU pulls a steady 140-160W. Frame time graphs are finally flat, with RAM sitting at 58-63℃.
