Well, there's an error I didn't get yet, I'm jealous! I thought I had collected all of them! :-) I have my tesselation on low...guess I'll turn it off so I can complete my error collection! But seriously, this is good information, exactly the kinds of experiences and knowledge we seek here...thank you, Yoland. A good tip for people. I didn't know that about pushing info over to the graphics card.
