   What should I know?
  I was wondering what all I should know before I start DirectX.  I have a pretty good grasp on C++.  Thanx for the advice.   
  I've been wondering the same thing. An answer would benefit me aswell.   ;  Well, a book will tell you all you need to know. My personal recommendation? Introduction to 3D Game Programming with DirectX 9. :)   ;  kool thanx
