Can someone explain to me how/why the fucking MINECRAFT maps on pavlov get my fps down to half of what they are on other maps? 
I can get 144 on cache or dust or sand no problem, but the second I get in a minecraft TTT it drops to 56-72, what the fuck?

how do you fuck it up so hard, the whole map must be 4k polys, and I'm sure I'm exaggerating
