Default 2D, Acceleration, And Windows: Aren't All Graphics Cards Equal?

In the first part of this series, a number of readers speculated that, with the introduction of DirectX 10-capable graphics cards and Windows Vista, older GDI methods for 2D graphics output were rendered obsolete. The WPF (Windows Presentation Foundation), along with Direct2D, have been available to Microsoft developers for some time now. Nevertheless, there are plenty of good reasons why GDI (the Graphics Device Interface) remains unarguably meaningful and relevant, which means we must examine its behavior and performance, even for the brave new world of Windows 7.

Update by ATI Hotfix:

As you can see, the performance in Catalyst 10.1 (our hotfixed version, not the publicly-available driver) is substantially better than Catalyst 9.12 with Aero enabled, in the case of polygons, even surpassing the performance of 9.12 in Windows XP. This is the fix we've been looking for.

LOL, I'm scoring *909* with win 7 64 bit and 5870 (10.2 drivers). Something must be wrong...

Retested : can we get lower...

seems you need that hotfix more badly, the "line" benchmark suffers the most from this bug.

It's in the line with their findings. There's a bug with HD5xxx hardware and software drivers which causes this low performance in 2D with Vista/7
