I am using D3DDECLUSAGE_POSITIONT( in dx9 ) to draw overlay objects. Everything works right, But antialias... When i open antialias, the overlay rect has a blur edge. There is a way to avoid it when card set "Use application setting". http://www.gamedev.net/community/forums/topic.asp?topic_id=466438 But, How to make it work when card force to Antialias? Thank for any replies.

ok, guys.
I have to ask artist add border to the image used for UI.

If anyone know the API can change video card setting( about force FSAA ), please tell me, thanks
