Ark 2 has terrible input lag during terrain loading on my Biostar B650MT. Is this a hardware flaw?

This board handles massive dinosaur model data like a snail. Memory response times were jumping between 70ns and 90ns, and that stuttering was just ridiculous. I tried enabling 'Ultimate Performance' mode in Windows, but it only shaved off 2ns and the spikes remained—a total waste of effort. I went into the BIOS, disabled every single memory power-saving option, and toggled High Performance mode. Monitoring showed response times stabilizing between 62-66ns. I noticed some slight frame drops immediately after, but locking the memory voltage at 1.38V fixed that. With the chipset temp between 45℃ and 50℃, the overall fluidity is night and day, and the input feel is finally precise. Hunting for issues in low-level timings is a joke, but it actually worked; frame variance is now within ±5 FPS. Exported all timestamps via a latency analyzer to verify.
