Does the TNT2 support this extension.
And what's the difference between WGL_EXT_swap_control and GL_WIN_swap_hint (which by the way is not listed in the extension registry) ?

Yes, all our HW supports this; it's a programmatic way of controlling vsync.

I don't remember the specifics of WIN_swap_hint, but I think it has something to do with telling us what part of the window is dirty for a SwapBuffers. (???)

i havent been able to get the swap winrectangle extension to on my vanta with win2000. i recall about 6months ago i was able to do it but under win98 (dont have win98 installed anymore so i cant check that now). anybody know whats likely to be the problem, im guessing win2000 doesnt want to obey the hint like win98 does.

Well, it is a hint, not a requirement. So if it gets ignored, I'd expect that the app shouldn't care...

I don't know why you aren't getting it to work. I'm away from work for Thanksgiving and so I can't look at our code for the moment.
