I'd hate to sound like the "contrary" guy, but I always had much problems with my GeForce cards and Vue. The one that I had on my second desktop PC always gave me problems in the visualization of OpenGL previews, which I had to disable (and I'm speaking of Vue 4 Pro not of Vue 5 Infinite, which also had problems with it but is more recent software, so it could be more understandeable), until finally I dumped it last month and got an ATI Radeon card which works perfectly. Same with my laptop, I bought one with a GeForce in it and I am regretting my choice everyday I turn the laptop on and start Vue. It scrambles my OpenGL preview, although not as bad as the desktop PC card. On this computer I am writing with, which I had to upgrade recently due to motherboard crash, I have installed a new ATI Radeon whcih is a dream and very fast. From now on, for me, only ATI Radeon cards, at least until Vue will remain my main 3D landscape program (which is going to be for a long time). Orio
