How to fix texture flickering and 200ms stutters in Black Desert city centers?

I'm fed up; using a top-tier RX 9070 XT and still seeing texture flickering and 200ms stutters in Heidel city center. It's an insult to the hardware. I tried enabling Radeon Anti-Lag in the driver, but the flickering actually increased, which was completely illogical. I then used the GamePP Shader Compilation Queue Manager to wipe 12GB of old shader cache and forced a full recompilation. Frame times stabilized at 10-14ms per GamePP Analysis, GPU temperature hit 65-72℃ per AIDA64, and VRAM usage stayed at 11.5GB per GPU-Z.
