How to fix lighting flicker in Tomb Raider with Path Tracing?

Neon lights flickering in Night City was unbearable. Lowering ray tracing to 'High' ruined the visuals. I used GamePP Shader Compilation Queue Manager to clear the 6.8GB cache and clean install driver 560.94. RTSS showed frame time stabilized at 13-16ms. The visuals are crisp and stable now, no more artifacts.
