ATI 6870 not overclocking (Low FPS)

[Flanker35M]

S!

I left CCC open and alt/tab to check clocks during game. They did not go higher than 500MHz. I overclocked the card but still the same?!

Also these black cursors people talk about are gone for me. I closed all the info windows, could that do it? Also overriding AF in CCC helped with graphical artifacts.

I tested Very High settings and got 11-38FPS over sea/land. Lowering to High helped a bit, but there is a lot of pauses and stutter. When these issues are solved the game will look simply gorgeous

I have a pair of 4850's in crossfire, but they are not both working in this game, the splash logo comes on in other games but not this one.

I did go into CCC and allowed the auto tune to OC it.

If you can explain I'll check what you ask.

I have a second monitor and have the CCC open when in game for monitoring.

The setting for force maximum clocks is only in the ati tray bar. right click, select your top card (either one will work) than 3D settings and than force maximum clocks/enable

If that does not force one of your cards to ramp up to 3D speed than you will need to disable one of your cards.

S!

Same here, no override option on 11.3's.

Any help?

Noticed the same behaviour with my 4850 - the core clock speed remains at the idle underclock speed of 160MHz throughout the entire game session, confirmed using GPU-Z sensor logging. This doesn't happen with any other games I have tested, just CoD.

I'm running v10.10 of the Catalyst drivers and don't see the force clock speeds option either. However, I was able to force the clock speeds using the ATI Overdrive option in ATI Tray Tools (http://downloads.guru3d.com/download.php?det=733).

Unfortunately, forcing the clock speeds didn't seem to noticeably improve performance.

Right-click on the ATI Tray Tools icon in the taskbar and select Hardware | ATI Overdrive 5. For reference, I'm running ATI Tray Tools v1.7.9.1557

Sorry but I have to concur on this one. No override in the 11.2 version 64 bit W7 here
either no matter where I look.

On the other hand I don't have the option for individual profiles activated?! Perhaps
one can do it in there?
