When I had a razer mouse (never again) and my old PS/2 logitech keyboard, no problems... Then I got my sidewinder X6 keyboard, the problem came back - 80+ FPS went to a 30-35FPS... Then when I got my MX revolution, the 30-35FPS went to a 15-20FPS.
EDIT: Forgot to mention that Prototype has the same issue, except when the problem is there, the game doesnt use any GPU acceleration at all.
with G9 and G15 my FEAR FPS was cut to 15fps.
never was fixed, so I never tried it later on.
