I am having absolutely terrible interaction performance when I am trying to move something I clone. I have a 6k poly pillar and I create 4 clones of that and try to space them apart and at best I get something like 2fps when moving them. It makes positioning clones a huge hassle. I am on a i7 920 with 6gb ram and a gtx 470. Modo is quite fast otherwise but time and again I get extreme slowdown with certain operations.
Any idea whats causing this and if there is anything I can do to fix it?
