Why are textures flickering in shadow areas of Shadow of the Erdtree?

Entering the Shadow Lands, I noticed eerie white dots flickering on the edges of ancient buildings. It was incredibly distracting during combat. I tried lowering the Ray Tracing settings, but the flickering persisted while the image quality dropped significantly, which was incredibly frustrating. I then used the GamePP Peripheral Driver Conflict Detection Tool to disable a legacy lighting service that was hijacking interrupts. 3DMark stress tests confirmed the error rate dropped to zero, GPU load hit 88-91% per HWInfo, and core temperature remained stable at 62-67℃ per AIDA64. It stayed at 67℃
