Hi all, I remember from a few years ago when I was looking into DirectDraw that the API (and probably D3D, too) allowed switching to some kind of "exclusive fullscreen" mode, I guess for efficiency reasons. Now I wonder if OpenGL (on Windows) or some Win32 API function provides something similar, or if it's not possible/neccessary at all. (Right now I simply use a top most window without border and change the screen resolution if required.) Any hints? (I'm using plain OpenGL, no glut or gameglut.)
