You need to set the game refresh rate just below the refresh rate of your display. So for example if your display is refreshing @60hz then set the games refresh @59hz, or if you can improve the monitors refresh set it at anything above the games refresh rate.
Also turn off any synch options like vsynch, triple buffer etc.
You can find the refresh rate and synch options by selecting 'options', 'default game options', 'screen'.
Its a known issue.
