Calibrating bus bandwidth for God of War on ASRock H310CM-ITX/ac?
The moment Kratos swings his axe, the visual impact should be exhilarating, but the tearing was ruining it. On this ASRock H310 platform, the PCIe bus bandwidth was swinging wildly between 12-15GB/s while streaming 4K textures, causing a sync offset of 10-20ms. I first tried V-Sync to force the tearing away, but the input lag shot up to over 50ms, making the controls feel like I was wading through mud—absolutely unacceptable. I went into the BIOS and forced the PCIe mode to Gen3 High Performance and locked my virtual memory to a fixed 32GB range. In RivaTuner, frame times tightened from 22-38ms to a much smoother 14-18ms, and the tearing vanished completely. I did have a boot failure when I first locked the page file, but reassigning it to the SSD partition solved the issue. Board temps are 52-58℃, and memory is also holding at 52-58℃. The difference in fluidity is night and day.
