Does XFree86 video driver support VBlank(Vsync)
interrupt? If it does, how to enable it?
I know some librarys offer function calls to sync
to Vsync (linke SDL_Flip), but they use
polling instead Vsync interrupt. The performance
suffers a lot.
I did some experiment by probing the vidoe
interrupt pin on the AGP VGA card. It's active
under MS Windowns but not Linux. I just don't know
why Linux doesn't support a basic and vital
function like vsync interrupt?
