Haha nope my bad. I meant the QT 2GB file limit bug thats been plauging OS X and Adobe products since CS5. Its documented and very much talked about in the Video world. I tried to get some answers at last NAB but I was totally ignored.One reason I can't answer that question is because I don't even understand it haha! I'll take a wild guess that maybe you're talking about VRAM? Do they make cards with more than 2GB of VRAM? (I am a graphics expert but not a graphics card expert)
