Why is my ASRock H310CM-ITX/ac choking in Cyberpunk Orion?
Cruising through the neon streets was a nightmare with these erratic frame spikes, making me seriously doubt this old ITX board's throughput. The PCIe link on the ASRock H310CM-ITX/ac was struggling with high-concurrency resource requests, with latency swinging between 18 - 42ms, which basically choked the rendering pipeline. I first tried toggling 'High Performance' in the drivers; it bumped my peak FPS by maybe 5 frames, but the 1% lows were still abysmal—a total waste of time. I eventually dove into the BIOS Advanced settings, forced the PCIe speed from 'Auto' to 'Gen 3', and disabled every useless integrated peripheral to clear some bus bandwidth. Monitoring via RTSS showed frame times tightening from a wild 15 - 35ms jump to a steady 11 - 16ms range. Interestingly, my boot time jumped by 2 seconds after locking the mode, which I only fixed after killing the 'Fast Boot' option. VRM temps hovered around 58 - 65℃, and the system finally stopped tripping. After several stress tests, the bottleneck is gone, and frame times are rock steady at 11 - 16ms.
