If it's an Nvidia card, it's possibly the render frames ahead function. Apply coolbits to unlock all control panel features, then go into advanced 3D settings. There should be a "Max frames to render ahead feature" that has a 3. Reducing that might help.

This is also my greatest complaint on the UI side, and happens all the time (no SLI though, just a humble Geforce2Go getting 3-10 frames/sec). Cursor movement shouldn't be reliant on frame rate though.
