Battlefield 3 punkbuster not updating
Most users report only the performance boost, including inside closed areas.
This is a known issue which affects a small minority of our users.
The first thing you should do to try and resolve this is disable Windows Aero while playing the game; this can give you a surprising boost in performance.
To do this, simply tick the "Disable Windows Aero" checkbox in BF3 Borderless (available since version 1.2).
I've tried re-installing the game, re-installing my Windows 7 (64Bit) TWICE, I've tried disabling DEP, repairing it and pretty much every fix I could find from Google and on Battlelog forums, but nothing helps.
I know it's not a program interfering because I've tried disabling all processes from my side and only running BF3and I'm starting to think it's a hard ware issue.
