Hi
I have 512MB ATI Radeon mobility HD 4570.Recently I installed ATI Catalyst 9.12 hotfix driver( for windows 7). I observed that all my openscenegraph application are rendering very slow saying dat it is not finding some driver functions (something like wglPixelFormat..()). When I revert back to my natvie driver came along with the card. It s working fine. Is ATI Catalyst 9.12 hotfix not supporting my card? or Is fullfledged ATI Catalyst 9.12 hotfix driver available now?
