If you have bought the just released PC version of F.E.A.R. 2 and have an Nvidia GeForce graphics card in your PC, you might want to consider downloading some newly released beta drivers for the game. They are supposed to improve performance while playing Monolith's new first person shooter sequel.
In fact the new 182.05 beta drivers offer even more than that as they add full support for OpenGL 3.0 along with new drivers for the PhysX game physics software. There's also been some performance improvements made for games like Fallout 3, Half-Life 2 and Left 4 Dead. The beta drivers are for both Windows XP and Vista in their 32-bit and 64-bit versions.
