I have a desktop and a laptop (which is not bad, that's alienware M11). On the desktop I don't have any problems. On the laptop, even on all "low" settings whenever I take something in hand, such as a rock, or anything, the item lags behind the mouse pointer severely (like quarter of a screen). Is there anything I can do to reduce lag on this laptop?

Change all your settings to low, also you could try resetting your driver settings to default values in display driver's control panel. Also try downloading the latest driver.

What is the Laptops spec? It may simply not be powerful enough.

Try alt-tabbing out then back in at the main menu.
