I double that. GDI and DirectDraw are different things.
Nearly all cards have for some years supported *both* GDI acceleration (from
Windows 3.1 days...) and DirectDraw acceleration (from Windows 95 days...).
Although they support both, they are different sets of code for different
purposes.

Then, why do you require DirectDraw support for activating acceleration?
Is simply.
When no acceleration is, the GDI calls are rendered manually, when it is
activated, they are rendered through DirectDraw.
No they aren't. Please trust me on this, I know quite a bit of details
of the Windows NT (and 9x also) architecture and this is just not true.
