Shadowproxies?

#1
Hi!

How much shadowproxies can improve performance if used with vegetation, trees and bushes for example? I talk about dense forest, something similar to Kingdom Come: Deliverance. I know that they also use shadowproxies for vegetation.

I need to create additional low-poly model of a tree for example, which will be used for casting shadows. This should decrease shadow triangle count a lot, but on the other side this low-poly model will increase my overall triangle count, because now i have 2 meshes: my main tree render mesh and this low poly shadow proxy mesh?
