Thankyou very much.Now I get to know what is the real thing.My CPU is slow,and this is a big issue,Anyway I like to play without audio and play other mp3 songs side by side.This was really helpful.Though,I can Run WWE 12 without any problem with disabled audio and other games like SGM and COD MW 2 with full speed and I have not found a video or graphic issue till now.But WWE 13 is a far better graphiced game than WWE 12 and I may face problems.My conversion of raw Graphics and all is not cleared till now but,This forum as well as the reply were fast and good and Maybe it is the correct solution.I can play certain games well at full speed but some do have problems.
