I love the game but Im really dissapointed with the optimalisation. Both native and WFaS work well for me with everything set on high. NW in Dx9 mode, but everything set on low is unplayable on some of the maps when the FPS drops to 17-25. Of course, my PC is not some kind of monster, but I thought that the GF9800, 2 Gb RAM and 2,6 Ghz Dual Core could handle that game.
