How do I stop lighting flicker in Metaphor: ReFantazio night scenes?

Neon lights in the Night City nightclub were flickering and tearing. I tried lowering ray tracing, but the visual quality was unacceptable. The Corsair Vengeance LPX DDR4 3600MHz 32GB was fine, but the shader cache was the bottleneck. I used DDU to clean install driver 560.94 and cleared 6.8GB of cache via GamePP Shader Compilation Queue Manager. RTSS monitoring showed frame generation time dropping from 22-35ms to 13-16ms. The screen is now stable, setting a perfect visual standard for my playthrough.
