i am curious to know how is a way of doing blitter in directx.
Presently i am using winapi blitter but this is somewhat really slow
on my old machine for big window it can reach (maybe a pair clear
and blit i measured this some time ago so i do not remember) close
to 5-10 miliseconds so it is quite slow.
I asked and i know how to do it in ogl - just by setting/uploading the texture to fullscreen quad, but i am curious what is a good way of doing this in directx.
Is this the same way of some call that uplowads a ram-pixel-buffer to quad texture or something other? can someone wrote mi the name of the api call
which exactly "blits"/uplowads it?
