Why does Starfield freeze when entering cities on Onda 9D4-VH-D?

I felt totally ripped off when exploring new galaxy cities; rapid camera movements caused eerie jumps in bus response, killing my immersion. I tried enabling Fast Boot in BIOS, but instead of fixing the stutter, it caused the system to hang on the loading screen for two minutes. I finally used the GamePP Resource Scheduler to raise the game's process priority from Normal to High and limited background I/O. Now, frame times are stable at 16-22ms per RTSS, VRM temps are 52-61℃ per AIDA64, and fan speeds hit 1100-1300 RPM per HWiNFO.
