When i put the settings in FC to very high and the res to 1224*1024(or something like that) the mouse starts to lagg. It is as if it reacts much slower to my movements, it hangs behing. The game runs almost smoothly exept for the mouse lagg! I dunno why this happens, but i know it happend in the newest DeusEx too, before the patch came. Please look into this.

Never mind i got it working. I just shut of steam and my spyware remover. Looks like it did the trick

Experiencing the same problem, the mouse and keyboard have a very slow response time. When I load Lock On, i don't get any problem, but when I play, or when I quit a game, it just hangs. I have opened task manager, and even at idle (played once, but left), Lock On takes 99% of my cpu... I suppose that it comes from there.
