Does anyone have any good links about inputing directly to the graphics driver? (Like OpenGL and DirectX does)

my guess is some memory addresses are mapped for i/o to the device and there's probably some proprietary format for the data for each device, so you'd probably need information from the companies that created what ever you want to communicate with.
the prospect of communicating directly instead of using the OS API is interesting, i guess it's not a very practical thing to do other than just for satisfying curiosity. don't bother doing it unless it's just for that.

DirectX doesn't write directly to the graphics memory in user-mode, it uses the driver itself - the graphics memory is not visible in user-mode.
Further, it is faster to send commands to the graphics processor than to write to the graphics memory, unless you are doing something really strange.

Compilers can produce warnings - make the compiler programmers happy: Use them!
Please don't PM me for help - and no, I don't do help over instant messengers.
Thanks for replys, I didn't know it would be so much trouble to that.
