How do I resolve lighting flicker and frame time volatility in Ghostwire: Tokyo with Path Tracing enabled?

Neon lights flickered badly in night scenes, with frame times jumping between 16-28ms per RTSS. I tried lowering RT settings, which hurt the visuals too much. I used GamePP Shader Compile Queue Manager to clear the 5.8GB cache and installed NVIDIA Driver 560.94. GPU-Z confirmed VRAM usage stayed at 11.2-12.8GB. RTSS showed frame times stabilizing at 11-14ms. This set the stage for a flawless visual experience.
