Re: nVidia 330M framerate problems
Sporadic loss of FPS doesn't sound like driver problems, driver problems usually manifest themselves in much more serious problems, or at least make it seem much more serious. Turn all the settings down to lowest and see if it still happens, that way you can rule out the chip being the problem. If it's an online game it could be the up/down speed of his internet connection, or like Echo says, if his drive is painfully slow, the game would slow to a crawl while it pulls game files.
