Attica makes CPU use 100% and Game lag

i played multiple Matches before w/o any Problem - then i got Attica and i immediately had Lagspikes throughout the whole Match, checked Task Manager and the Game was using up 100% of my CPU. Second Match i got Attica again, turned down the Terran Displacement Quality 'cause i read that is causing issues but - same problem persisted.

Then i got another Map (Campania) and it all worked fine again, turned the Terrain Stuff back again but worked all fine. Next Match Golden Quarry all worked fine.

Attica still causes my CPU to use up 100% and the Map lags. Its the single only Map doing that since the Update came out every time i get it.
