I really love the idea behind this mod. However I am having some issues with frame-rate drops while having the mod in my load order: When looking at an empty piece of grass I usually get about 40fps. When the Parallel Road Tool 1.0.0 is enables, it drops to about 26fps.
Funny thing is, once the help dialog pops up, I'm back to 40fps. But after I close the Parallel Road Tool, the frame rate drops again.

I hope you can find a solution for this.
