Well all I can say is this.....I have Nvidia 9600M GT...which SUDDENLY stopped being sompatible with Maya 2009 High Quality viewport. I upgraded drivers etc etc uninstall re install ad nauseum. Now I had it working with 2011...until just then..no joke...now AGAIN Maya will not recognise my card...Im over it...I will just have to bloody live with it again. I would do some serious research first mate.
