How to fix bus bandwidth jitter on the Onda 9D4-DVH?
That feeling of gliding across the open plains is finally back. Before this, every time I made a sharp turn, I'd see these tiny, annoying micro-tears in the image. The Onda 9D4-DVH was struggling with the massive texture streaming of the Remastered version, with the PCIe bus bouncing erratically between 40% and 85% utilization, creating 10-22ms of GPU data latency. I tried enabling Low Latency Mode in the NVIDIA drivers, which gave me a measly 3 FPS boost but did absolutely nothing for the tearing—it was clear the issue was deeper in the hardware. I dove into the BIOS and forced the PCIe slot from 'Auto' to 'Gen3' and slammed the latest chipset drivers. In-game, the transitions became seamless. It wasn't without hiccups; the system failed to detect my GPU twice after the change, and I had to reseat the card to get it to post. Now, the board stays cool at 48-55℃, and the bandwidth is consistent. Total relief.
