Just get a decent opengl graphics card and throw away your gaming card which was NOT made for any serious 3D work.
It's that simple.
It depends on just how serious you are about 3D.
I guess though that most users here are just part time hobby users so you guys and gals will have to put up with it and keep a-grumblin' and a- grumblin'
It's been happeing for years and people have been posting complaints like this for years
If you must use a gaming card, cut down on it's patheteic implementation of opengl and use a less intensive document preview window mode as already suggested...
If you are seriously concerned..GET A DEDICATED OPENGL CARD. :)
