How do I fix the lighting flicker in Aka's night areas?

The neon lights in Aka were flickering and tearing, making the game unplayable. I tried lowering ray tracing settings, but the visual quality suffered too much. I then used GamePP Shader Compilation Queue Management to clear the 6.8GB cache and reset the queue. RTSS showed frame time dropping from 22-35ms to a steady 13-16ms. GPU-Z confirmed VRAM usage settled at 12.4-14.1GB. The graphics are finally crisp and stable.
