i want to find a idea to implement :
let video card to draw all the visible things, do not use cpu's Instructions.
it's means that to use hardware acceleration possible for the visible controls.
to give only a form design (e.g. .frm files) ,
For a window that uses any of the Windows "facilities" (caption, menus, borders, controls, bitmaps, anything that is Windows specific, etc), not really. Windows already implements those features using GPU instructions (when possible and depending on the version of Windows).
If you take full control of the screen (as many/most games do) then Windows will, for the most part, stay out of your way. Once you do that, forget "normal" windows and controls. You have to do everything.
