    I came across an article discribing the use of some usb devices that may reduce frame rates in Fear. I've never come across a post were someone claimed better frame rates when they disconnected all their usb devices. In all honestly I am not sure if you can disconnect all your usb devices, specially if you use usb keyboard and mouse. Is there anyone out there that can test this?

    I guess it's possible if Windows has to use extra CPU cycles to control USB devices.

    EDIT:Skimming through the article it seems even more likely, they say it's a problem with Directinput, which is the input device controller of Directx.

    it's been proven in armed assault: unplug/plug mouse and keyboard and frames goes 20% up.
