Forged Maps Frame Rate Issue

I have made a map that has serious frame rate issues when I launch it in custom games, but I am below 60% on all of my limits. Can anyone tell me how to fix this or at least why it is happening?

Safe bet is that you have too many objects in the same frame, try using less objects, spreading the objects out, or deliberately limiting lines of sight on your map to decrease the number of objects that can be on screen at once.
