How can we limit number of frames/sec. The process in tut23 is very vague, and difficult, is there any other way to get clock tick and make the framerate stick to something like 60 frames/sec.

try someting like this...

void DrawFrame()
{
static DWORD t = 0;

...

while( GetTickCount() < t )
;
PageFlip();
t = GetTickCount() + 100;
}
