Triple buffering can be used on cards which can schedule changing of "active buffer"
during next vertical sync. And I guess it can be fast of double buffering.
Btw - when I tried to change to use double buffering - I only lost performance.
I do it on vsync - but it can dramatically slowdown execution.
About flickering - see my previous email
