In a decent game, they are going to be backing up render buffers
so that the video card is never NOT rendering. You get better control
from within the game in terms of grabbing a surface DC after the render
happens or better yet rendering a quad with your GDI/GDI+ output.

In short order this would not be an easy task if possible at all. Video card
management of the video buffer is fully asynchronous where possible and
definitely not easy to plug into from an external standpoint.
