Did you update the graphics drivers for both video cards?
I actually didn't update the integrated card, there wasn't a button right on the taskbar, so I thought it wasn't necessary (you have to dl a utility program from their website)
It seems to work now I think, Thanks again for the help everyone
At least I can tell you what's a huge memoryleak; the Way Systems. Before upgrading the drivers the studio crashed a lot when I tried to access the way systems tab in one scene that has an ation area. (even if it ran fine on everything else)
