Re: Why is Vista 2D Graphics & Text performance so bad compared to
Well, it is a beta driver. The final drivers have not be released yet.
Graphics processing has changed quite a bit in Windows Vista and drivers
need to be updated accordingly. Try your benchmarking again once you get
final drivers, they likely will be more efficient.
