Can USB devices effect some games performance?

EastCoasthandle · Jul 18, 2007

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?

Um.............. dunno how to say this but, the SB is linked off the NB...... and thus wouldnt really affect anything.

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.
