I updated my Vista64 drivers a while back and they've worked reasonably well except for the 'Desktop Window Manager' falling over every time I suspend/restore my system. Figured I'd try the latest and greatest drivers this evening before I got down to proper development.
*sigh*
I've lost ALL hardware acceleration now. No fancy Aero, no D3D9 and definitely no D3D10.
Dontcha just love these completely random cycles of install-uninstall-install-uninstall that somehow eventually seem to work with no discernable reason why it didn't work the first time [rolleyes]
