Pacific Drive is hitching during map transitions on my Onda B760ITX-B4; should I change the bus priority?

This is unbelievable; I bought an ITX board and ended up with missing assets during map loads. The compatibility is just pathetic. The Onda B760ITX-B4 was having scheduling conflicts between the NVMe drive and USB peripherals, with a 0.2-0.4% collision rate that pushed load times from 5 seconds to 12 seconds. I tried killing all background apps, which only lowered CPU usage by 1% and did nothing for the speed—a complete waste of time. I eventually went into the BIOS, forced the PCIe slot to Gen4 instead of Auto, and updated the storage controller drivers. In CrystalDiskMark, the random 4K read latency dropped from 1.2ms to 0.6-0.8ms. I had two boot failures after forcing Gen4, but clearing the CMOS fixed it. Drive temps are 45-58℃. Diagnostic tools show zero errors now, and the config is backed up. Temps are still 45-58℃.
