Hello. I have just switched workstations. Previously I was running C3D 2011 on a pretty descent machine. 8GB ram, 1GB dedicated video, i7. Pretty smooth for the most part. My new machine with C3D 2012 has SSD, 16GB Ram, 3GB dedicated video, i7. Seems like it should fly through drawings no problem. Some drawings are performing fine, but other have an tremendous amount of lag. They are pretty much unusable. Any ideas on what could cause the decrease in performance? It seems like drawings that have x refs could be the offenders. I know we could get into whether the video card is certified...ect, but it seems to me that its a bigger underlying issue. Any comments are helpful. Thanks
