Thanks a lot

Ah, sorry I didn't notice that youre talking about ATT and assuemed it was about CCC
My bad sorry. I need to install that again :D

open the catalyst control centre (im running the latest drivers) click on performance then clock controls, then amd overdrive, you can see your current values at the bottom of the amd overdrive interface,

in order to change anything on this screen you will need to click the little key icon above "enable AMD overdrive" to unlock the interface and allow changes

if you have the benefit of two monitors you will be able to monitor this in game, both my gpu clock and memory clock increase when the game is running and at 890 mhz and 1215 mhz on the ram my performance in game was pretty much unchanged.

the game as others have mentioned is hardly touching the CPU im only using 17% of cpu capacity and only 2 gig of my 6 gig ram is used

I'll also confirm that AMD PowerPlay (the thing that downclocks AMD cards when they aren't in use) does not work with Cliffs of Dover at all. It is like it does not consider Cliffs of Dover to be a 3D game.

My GPU/Memory clocks registered as 500Mhz/500Mhz using GPU-Z sensor logging. Their normal clocks during 3D gaming are 750Mhz/900Mhz.

Overclocking the clocks using Overdrive in the CCC will not have any effect as it does not disable PowerPlay which is what controls the GPU and memory clocks. Only forcing settings for the clocks using a third-party utility will get around this.

I'm quite annoyed learning about this today. Its clear that this game was not tested with any AMD cards at all. Its time to get out of bed with Nvidia now.

Got similar problems with nvidia card.
First clocks are at normal 3D clocks but suddenly after some time go down to 400 coreclock. I recognized some memory overflow posted in another thread with screenshot.

Ok, this is what I just got.

If I'm reading it right the first card is not being used, but the second one is 100%?

Catalyst Version 11.2

ATI Radeon HD 4850 x2

That's strange, but at this moment crossfire is nog supported.

Have you read this ;)

All the answers for low fps...

Salute !

So once we've established that our AMD Overdrive is enabled, but the GPU clock doesn't go above 500 MHz whilst in game, what do we do to force faster clocks?

S!

Would be nice to know as I am sure a missing 380MHz will affect performance...
