Hi, many thanks for replying.

Oh well, I feel so stupid now !
I was so desperate yesterday that I tried to install some ATI drivers which were listed as "mobility" but they promptly shot my system.
And when I used system restore, my german Catalyst Control Center was gone and with it the crossfire mode for my video card.

So, as a final attempt I browsed to the german ACER support website and guess what ?
Despite everyone sayin' that my drivers were the latest and that there were NO drivers to be had from ACER, there WAS a download for my machine.

And it installed a brand new CCC that now let's me fiddle with every little setting my video card has.
Seven settings alone for 3d !

I feel so...professional now. He He.

AND of course shiny new drivers and new OpenGL and Poser-8 now FLIES !

Sure, there might be still some bugs here and there, but I now can WORK while waiting for the first SR.

Thanks to everyone at SM for doing such a great job !
