Does anyone know of any mods that make use of the Dynamic Light check button in the CS? All vanilla lights seem to have that off but doing a quick test, I made a new light source with that option available to avail no noticeable difference. Does anyone know what exactly it does?

The Real Lights portion of All Natural checks that box on the vast majority of light sources. I can't say I've ever noticed a difference either but at least it doesn't cripple performance.

Ahh thanks for the reply. I was hoping checking it would solve the 'bleeding light through walls' problem but it does not. With my question answered, this can be locked now.
