Shadow Projection on Opaque using 15-20ms - Possible to Disable?

So I am trying to increase my FPS, and ‘profilegpu’ shows ‘Shadow Projection on Opaque’ is using 15-20ms, half or more of my entire frame time. This seems like a crazy amount and far over represented.

Is it possible to disable somehow? Am I doing something wrong? Workaround? 4.10 from source.

You should provide a bit more details about your actual scene.
