DelphiX and hardware property

[patroclus02]

As I heard, DelphiX does alpha effect by software (and that's why it is so slow). What is the DXDraw.Hardware property for then

[Useless Hacker]

I think that property is probably for 3D. DirectDraw does not have hardware accelerated alpha-blending (and rotation), which is why DelphiX does it in software.

From the DelphiX help:

doHardware -- The hardware acceleration of Direct3D is made effective.

The DoHardware property is set true if you want the card to do the rendering (if it is capable of it), and false if you want all rendering done in software (whatever the capability of the card).

Usually set to true, the thing will automatically kick back to software rendering if it gets too much for the card.
