I'm a little disappointed that Archicad 11 seems to be slower than AC10 on my MacPro with GF7300, in 2D redrawing and more in 3D OpenGl redrawing (not rebuilding). I mean, if I rotate my 3D model, I see a lot of library objects to disappear, this is the normality on my MacBook with integrate graphics, but should not be on my MacPro (and is not on the PowerMac's G5 I've tried, all with ATI card, even much older like radeon 9600). Has any other the same problem? Is this a driver/card issue? Are there any settings that can cause this problem (but on G5 I've all same settings)...
