Ok, so i installed d3 and everything went fine. i opened the client and watched the opening video with no problem. Then the login screen. Every word i type has about a 1-1.5 second delay before it shows up and when i click on something in game or try to move around, it also is delayed and quite laggy.

Please help me as i am unable to play and i am becoming quite frustrated with this problem

Im running a AMD athlon(tm) X4 645 Processor 3.10 GHz. 6 gigs of ram, on a 64-bit operating system.
