Problem when viewing image in 3D window

[Anonymous]

hello, i am running Archicad 11 with XP. I have a machine running 2 Radeon X1650 256Mb graphics card, crossfire activated & the latest driver installed. Occasionally the 3D image in the window disappears BUT when rotating & zooming the 3D images appears again, i have un-installed and re-installed Archicad but it still occurs. Strange thing is it does not always occur, only after a while of working on the drawing. Has anyone got a possible solution to the problem PLEASE HELP, its driving me nuts! The only way to sort it out, is to shut down and restart.

I had the same problem in the past with v.10. I couldn't find the solution but then when I used a same machine with a different graphic card it stopped happening. So I would tell you that is a graphic card compatibility issue. Without being 100% sure. There is a topic on this forum where you can put your card model and find out if its ok with archicad or not.
Im sorry I can't help you more!
