I'm finding the beta driver 190.15 is significantly better than 186.18 in gameplay.
Both are making 3DVantage error tho. I say erro, it runs but at less than half the usual frame rate and looks like its in 3d with the primary colours echoed on the sprites. Seems to much of a coincidence not be be something to do with the drivers. When the program starts it exits Aero
