[4eyes] Triple Buffering?

[Cha Lee]

Hey guys,

Do you know anything about triple buffering? I know what its supposed to do,
but I can't confirm it.

>From what I understand triple buffering creates two back buffers. So while
the display is being refreshed, we have two back buffers to render to and
can always render the latest data. This should increase the FPS no?

However, I can't seem to prove this. The only thing that increases FPS is to
disable vertical sync. Even with Triple Buffering on, it does squat to the
FPS. I am using glut and OpenGL to do this test.

This suggests to me that my draw function is only executed after every swap
buffer event instead of going as fast as it can. This sucks. I was under the
impression that Triple Buffering was handled at the driver level, and all
you could do was enable/disable it.
