How to eliminate color overflow and screen tearing in Nioh 2 night battles with path tracing?

I saw color overflow in Nioh 2 night battles. I tried lowering ray tracing, but it ruined quality. I used DDU to clean install drivers and cleared 4.5GB shader cache via GamePP. Per RTSS, frame time improved from 25-38ms to 15-18ms. VRAM usage stabilized at 5.2-5.8GB. These settings restored the atmospheric immersion.
