Official Catalyst drivers (now v2.3) are ok for your Radeon7500 but, as far as I know, the beta drivers I suggested are only for 8500 and 9500/9700
Wait the next Catalyst release... probably will include all the fixes present in the beta and should go well for your video card.
Or wait until the 1st DO patch is released... I'm sorry
The best way to fix any problem with an ATI card is to buy a nVidia card
hahaha
