Weird lag in build/buy mode and sometimes in Live Mode too

@MadPeachyTV  Thanks for the dxdiag, and yeah, you're probably not going to be helped by disabling the audio driver.  But you might as well try, since you also have both a driver from AMD and one from Realtek.  If that doesn't help, try playing in a clean boot:

Let me know whether it helps.
