Why does my screen flicker in Dead Space Remake night scenes?

I was terrified in the isolation zone as the screen flickered violently. I tried lowering ray tracing, but the visual errors persisted. I used GamePP Shader Compile Queue Manager to clear the 6.8GB cache. RTSS monitoring showed frame time stabilizing from 18-35ms to 13-16ms. The 3DMark benchmark confirmed the issue is resolved.
