The new patch for V5/V5P is superb. Been working on a scene today..with Yahoo open/Internet up and all other background programs running. NO crashes/NO slowdown etc. I was adding/deleting/moving around 70 plots of grass :) Procedurals, still at times give my puter fits. Especially while in the node editor, while trying tweak. Puter crashes. This is usually happens when I go beyond 4 mats per terrain. That said, I haven't tried messing with this since the new patch. That said again, it's all a moot point anyway, because once V5I arrives....this will be off my puter :)
