Hi David, The has lots of GL checks when setting up use of advanced features - anything above what is in OpenGL 1.1 is checked for!
In your case it's very likely that the difference you are seeing has nothing to do with the graphics card unless you are using a feature that the 7800 doesn't support and the 8600 card does. Much more likely is a driver bug. Robert.
