How do I fix the light flickering in ELDEN RING shadow realms?

The shadow realm flickering was distracting. I updated the driver first, but the issue remained. I used GamePP Shader Compilation Queue Manager to clear the 4.5GB cache and recompile. 3DMark showed the GPU temperature stable at 60-65°C, and the flickering stopped completely, restoring the intended atmospheric experience of the game without any visual glitches.
