Actually the card supports aceleration (in directx 7 is great) but to have it in directx 8 you have to install the old files of direct draw to make it work. (I take the driver 1.08 and mixed with 1.07 to make the deal).
Tha bad point is the color, its looks darker and the red seems brown.
I think that i have to install directx 8.1 and see what happend
Finally I installed directx 8.1 in my machine, the acceleration doesn't works whit the driver 1.08 (Certified for directx 7), replacing only the two direct draw files with the files of version 1.07 the acceleration works.
I think that the problem with 1.08 is the amount of Video RAM that counts the driver, some direct draw applications shows 2MB free, when really i had 7.
The problem with the colors is partially fixed, it's looks better but still has some problem whit red (looks some brow).
If someone needs the modified driver write an e-mail and i send it
(I do'n't give you any warranty, but it's works very well for me )
