How do I fix screen flickering and color overflow in Warhammer 40,000: Space Marine 2 with Intel Core i9 13900K?

In the Night Club, neon lights exhibited strange color overflow and tearing under full Path Tracing. I tried lowering the ray tracing level to High, which improved FPS by 15 but resulted in unacceptable loss of lighting quality. I used DDU to clean install NVIDIA Studio Driver 560.94 and cleared the 6.8GB shader cache via GamePP Shader Compilation Queue Management. RTSS confirmed frame generation time converged to 13-16ms. HWiNFO showed CPU temperature at 58-64℃, and GPU-Z indicated VRAM usage at 12.4-14.1GB, confirming stability.
