Nah m8... I never did use Procaff.
I did see a little bit of stutter when in F2 and looking at the rear of an airplane...
Did some research and installed this >>> AMD Opteron™ Processor PowerNow! Driver for Windows XP and Windows Server 2003 Version (exe) 1.2.2.2
But now that I look it's odd... Driver signing says 1.2.2.0 ... Almost certain its this one on this page no matter what the signing says.
