The owner had changed the polling rate on their mouse. I set it to normal and the keyboard lag went to the normal USB Keyboard lag.
You do realize that PS2 keyboards are sought after by gamers because they have the least lag?
Plenty on the web about that!
All usb i plugged in my pc works fine but for some reason ALL Keyboards is try to plug wont work properly. It acts as if its lagging.
Tried reformat OS. Also i changed my motherboard since this problem occurred to my old motherboard in hoping that it will fix the problem. But the problem is still there.
Oh. And PS/2 keyboard works fine.
(I have different keyboards that is acting the same in my pc. But when i try to use these keyboard on another pc/laptop they work fine)
What could be the problem? I'm suspecting my psu is giving not enough power
