Beware ATI catalyst Version 11.6 halved my FPS compared to 11.5
Any one else running 11.6 and COD ok?

Hippo

My performance is better with the new 11.6 version! I used the 11.5 and 11.5 beta, but both are worse then the new Catalyst!

HD 6950

I've noticed no difference between 11.5 and 11.6.

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. :eek:

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?

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