F.E.A.R. is a rather resource-hungry game and the increase in performance never got much better than 20fps. This is still a considerate increase, although in most instances the gain was a much more modest 2-5fps.
OK, so the Advent 4211 is MSI's Wind, sold under a different name, in this case DSG's in-house PC brand. But it's worth a look because of a couple of differences, most importantly the price.
