If you have an Nvidia card, you can set the environment variable __GL_SYNC_TO_VBLANK=1 or =0 to enable or disable vertical syncing, but this must be done before the graphics context is initialized. I'm not sure how to do it for ATI or Intel chips. A google search turned up this tip for ATI cards: http://www.stolk.org/debian/vblank-fglrx.html (I haven't tried it though).
