How to fix PCIe link bottlenecks on Biostar H310MHD3?
During the flashy combat scenes, I noticed these tiny screen tears and hitches. It was actually exciting to see just how much a budget board could struggle. The H310MHD3's PCIe link was introducing 15-25ms of transmission latency, leaving the GPU starved for data. I tried the 'Prefer Maximum Performance' setting in the NVIDIA panel, but the latency remained—another logical failure. I went into the BIOS, forced the PCIe speed to Gen3, and killed every single ASPM power saving option. The latency analyzer showed response times dropping from 22ms to 10-14ms, and the stuttering almost vanished. Disabling ASPM caused a 2-second wake-up delay from sleep, which I had to fix via the Windows power plan. Board temps are around 45-55℃. Switched the mode in the driver panel and it's finally playable.
