Installed these over the 101.70 Vista x32 drivers. So far I'm impressed with the performance. Tested in Oblivion and things are much smoother and quicker; running max settings at 1680x1050. Tested both the opengl Adrianne and Frog demo and both crashed while trying to open. Cascades however opened without a hitch and is running much smoother than before. OpenGL issue? Great improvement with these drivers! Digital Vibrance still greyed out..
