Beware ATI catalyst Version 11.6 halved my FPS compared to 11.5

Thanks for the reply Attila, here using HD5850 I have a repeatable result 11.5 good, 11.6 bad.

Maybe try full screen mode instead of pseudo full screen in CoD with the latest drivers as with my sapphire HD6950 and the 2nd pc with HD5970, the fps in 'full screen' are playing noticeably more smoothly.

Half fps means vsync started to work without tipple buffering enabled. Either switch vsync off or turn tripple buffering on: ATI Tray Tools >> Game profiles >> Manage profiles >> Direct3D Tweaks (create and save new profile for CloD).

I thought Triple buffering improved frame rates when VSYNC is enabled in game?

Exactly. This is what I mean. Without TB you have either 60 or 30 or 15 fps if vsync is on, you can not have 40 or 50 fps.

thought triple buffering only related to open gl?

Enabling Triple Buffering for OpenGL-based games such as Doom 3, Quake 4, Prey or Enemy Territory: Quake Wars is very simple - go to your graphics card's control panel and enable it from there. However enabling Triple Buffering for Direct3D-based games - the bulk of modern games - actually requires more effort. You will need to use a utility called D3DOverrider which comes with RivaTuner - see the bottom of this page of my Nvidia Forceware Tweak Guide for more details.

Fro ATI use ATI Tray Tools as described in my previous message.
