System Spec: AMD Athlon 64 3000+, 160gb hard drive, 2gb ram, Nvidia 6600gt AGP, XP Home. Installed Area 51 and installed the patch. Whilst playing the game particulary during firefights parts of the screen where the gun aim (the crosshair is it? +) is becomes very blocky. In fact when this first starts to happen If I move the aim via the mouse, everywhere the aim goes it wipes out the detail and becomes all smudged. Does anyone know why/how this happens? and how to remedy this. Thanks people.
