How do I fix severe color bleeding in Ghost of Tsushima?

I felt my immersion shatter when neon lights in Kamakura bled across the screen. I tried lowering ray tracing, but the visual drop was painful. I used GamePP Shader Compilation Queue Manager to clear the 6.8GB cache. RTSS confirmed frame time stabilized from 22-35ms to 13-16ms. GPU-Z showed VRAM usage at 6.2-7.5GB. This fix saved the night scenes.
