Option to Disable Shadows on Dead Mobs

This might be in wrong feedback section, but it sort of touches on art.

If there was an option to disable shadows on dead mobs, would doing so yield enough of a performance gain to help prevent the auto-resolution from kicking in? Specifically in ambush spots where the bodies pile up.

By the way, the auto-resolution system has been a great addition! <- Especially for the arena fight in Act 4.
