Can you limit the FPS to 60 within your graphics card's control interface? (for NVidia - in the NVidia control panel).
Do you have SLI or Crossfire? Does switching from Alternate Frame Rendering 1 to 2 (you can force this in the SLI control panel) help at all with the stuttering? (They're saying it does).
I'm not sure if you're asking me directly, but yes, I am running 3 GTX680s in SLI configuration.
I found that if I locked the v-sync in the NVCPL there was stuttering, even if I set it to Adaptive, so I leave it set to off and I get 100FPS with all of the settings as per my previously posted images.
