Severe Keyboard Lag in Crysis

[Vader]

Hi Guys, Ive finnaly got around to playing crysis and Im experiencing what I can only describe as severe keyboard lag.

When I use my WSAD keys to move, it usualy takes around 1.5 seconds for the movement to register.
You can imangine what that does when you try and drive the jeep.....

The weird thing is that Im only experiencing this with keyboard.
The mouse is file, so aim and shoot is right.

Frame rate is not brilliant but its ok, between 25 and 40.

On Vista x64, Q6600 with 4Gb of Ram & a 6600GT

any pointers?

I had the same thing but cant remember how i fixed ,but i did google to find the fix so try googling it

Fixed.
I dropped physics and shadows to normal, and increased resolution to my monitors native resolution.

This seems to have fixed it.
Not sure if it was just one thing or a combo of the three.

Might play around with it later.
