How to stop the VR stuttering on SOYO SY-A320D4+?
While sneaking through tunnels, I kept getting these periodic hitches that are absolutely nauseating in VR. The PCIe 3.0 lanes on the SOYO SY-A320D4+ were showing latency spikes between 15-22ms, making the frame delivery totally unstable. I cautiously tried lowering the VR render resolution, but that just made the image look grainy and the stuttering remained—proving the bottleneck was the I/O throughput, not the GPU. I went into the BIOS, locked the PCIe mode to Gen3, and disabled all the useless onboard audio enhancement features to reduce bus pressure. The frame time analyzer showed the variance shrink from 18-35ms down to 11-15ms. It's a huge improvement. I did lose audio for a second after the first PCIe change, but a quick driver reinstall fixed it. Board temps stayed around 42-48℃. Verified the fix via the VR performance overlay. Status confirmed.
