Weird key lag in PS

[ExZeRoEx]

When I'm playing and stuff I'll sometimes lose control of my character and it'll keep moving in the same direction that it was moving. Also, sometimes the typing is laggy too, so I'm guessing it's like a key lag.

Check your bandwidth settings in the PS options - play around with it a bit.
