Curiously I'm getting no performance differences with the new SSAO checked or unchecked. It makes hardly any difference atall.
Have also checked that COD is running successfully on all 4 cores (which it is).
Have also tried this patch on 2 different Nvidia drivers; the latest 270.51 Beta & a rollback to 263.09 with no change in performance but the Beta drivers were "causing the display drivers to stop working2 (error code 4).
My system.
Intel Core Quad Q8400 @ 2.66GHz 2.67GHz, 4GB DDR3 RAM, ZOTAC Nvidia GTX 580 amp! edition, Vista 64 with SP2, 32" LCD Display 1360 x 768.
