Keyboard causing drop in games

[no_1_dave]

All my games run smoothly when i'm standing still & wizzing my mouse around.
As soon as I start using the keyboard my fps drop making my games stutter really badly.
Anyone now why & how to fix it?

is it any key, or just the moving keys that cause the stutter?

I'm guessing that moving rather than just looking around causes a bigger geometric hassle for the gpu/cpu, and thereby causing a fps hit.

i see the same thing going on and have just put it down to that

- if it is usb unplug it and put in different port
- if it has drivers download and install the latest ones
- try another keyboard, ( usb if you have ps2 or ps2 if you have usb )

Tried different port etc.
Worked fine with my old GTX 275, this is happening with my new GTX 470. Must be a conflict with new Nvidia drivers & my keyboard.

I have put the keyboard repeat rate to low which has sorted it for now as long as I dont press loads of keys at once. Is there a better solution or is this probably a "wait for nvidia to release more drivers" thing?

Have you tired another keyboard?

Sounds like drivers for the new card rather than something to do with the keyboard.

I think there must be some sort of conflict.
I dont have another keyboard or a PS/2 keyboard around to test.
With the temp fix I have done it probably wouldnt happen on a PS/2 keyboard as they dont have that option (I dont think)...

Mmmmmm. Could be some kind of power drain on the USB port I guess, bit of a strange one though.
Have you tried different USB ports (in particular if you have front and back ports, try the opposite of where it is now)?

try changing the usb ports. What keyboard have u got?
