Frame Rate choppy with high end system

Can you try and check the control panel for the graphics card and see if you are forcing any settings like FSAA, or if you have any sort of optimization/auto settings enabled. Also, if SLI is enabled it can cause problem even if you have only one card and not actually using SLI.

You can also try and disabled Aero for Windows or any other program or process running that could cause a conflict.

Not saying to do this as a permanent solution, but to find a problem and conflict that we can then look into improving the game for.
