How to fix 0.5s freezes on Vastarmor Radeon RX 9070 XT Alloy in Black Desert?

While riding across the map, the screen would occasionally freeze for 0.5 seconds, which was jarring in Remastered mode. I first tried setting all graphics options to maximum, but this counter-intuitively worsened the driver response delay, making me very cautious. I then ran the GamePP Peripheral Driver Conflict Detector, found a resource conflict with an old chipset driver, and disabled the service. RTSS showed frame times stabilized at 10-15ms, AIDA64 confirmed VRAM temperature stayed at 45-52℃, and GPU-Z tracked VRAM at 11.0-13.8GB.
