How to fix I/O latency on Galax H310M Warrior D4?
When building complex interior scenes, I kept getting this rhythmic hitching that was incredibly obvious at 2K resolution. The PCIe 3.0 lanes on the Galax H310M Warrior D4 were showing latency spikes between 18-26ms, making the frame delivery totally unstable. I tried lowering the resolution, but that just made the game look like a pixelated mess and the stutters stayed, proving it was an I/O bottleneck. I went into the BIOS, locked the PCIe mode to Gen3, and disabled all the useless onboard audio enhancements to clear up the bus. Frame time analysis showed the jitter dropping from 22-38ms down to 12-16ms. I did have a brief moment where my audio disappeared after the tweak, but a quick driver reinstall fixed it. The board is running at 44-50°C, and memory is stable at 52-58°C. It's finally playable without those annoying drops.
