So the fact that you're getting framerate in-between 30 and 60 makes you think it's triple buffering? I've had that happen to me too even though I knew I wasn't running with triple buffering. That confused me and I made a thread about it here but no one gave me a satisfactory answer.Huh? I run The Witcher 2 at about a constant 45-50fps, and I'm not using D3DOverrider.
