Why does Banishers: Ghosts of New Eden have micro-stutters on DDR3?

While soaking in the eerie atmosphere, random micro-stutters felt like grains of sand on silk. I first tried disabling all Windows power-saving options, but while frequencies locked, the stutters persisted. I used the GamePP BIOS Load-Line Voltage Guide to switch to L3 mode and tuned VCCSA to 1.15V per CPU-Z. Frame generation time stabilized at 16-22ms per RTSS, and MemTest86 confirmed zero bit-flip errors. Temps stayed at 44-50℃ per HWInfo64.
