You may also want to verify that the environment variable __GL_SYNC_TO_VBLANK is not set. For certain graphics cards/drivers, this variable allows you to control the frame rate. If this variable is set to any non-zero value, the application settings will be overridden, and the frame rate will be locked to the monitor refresh rate.

This reminds me of something that I asked a while ago: as far as I can tell there is no way in OSG to modify vsync after the context has been established. At least the OS X code only checks the vsync trait on setup. I have a preliminary patch that adds this on OS X (key binding 'v' and code to toggle vsync at runtime) but it's a bit raw. Is it worth polishing this for submission?
