ATI blue stripes

I haven't had this underclock issue, yet Now, my 5870 is a Sapphire Vapor-X and comes overclocked a little from standard. When I saw a few weeks ago that someone was recommending AMD Overdrive - I turned it on and pushed the sliders up a bit. However, the last week at least, I turned it off.

Right now my CCC is for AMD Overdrive is set as follows:

Enable AMD OVerdrive = unchecked
High Performance GPU clock = 890MHz
High Performance Memory clock = 1260MHz

I have used the ATITrayTools monitoring graphs set to view Main CPU Usage and GPU Activity. My 5870 was running way over 80% - sometimes as high as 98% - during heavy load CoD application.

S!

Mine's very similar, my defaults are 850/1200mhz with ATI Overdrive on. The core never hits 850 as it does in every other game, just sits at 400 with GPU usage at 100%, which doesn't seem right to me. Latest beta gives me what looks like true fullscreen (which I assumed would solve the problem) but nothing has changed.

From what I've read it doesn't seem like CloD was ever tested on ATI cards, at least not on a crossfire rig, which to me is ludicrous as ATI/Nvidia make up a huge percentage of the market for gfx cards. After accidentally leaving xfire on after installing 11.4 I feel really bad for people with 6900's and other dual cards, it was a hideous experience. I just wish I could figure out why the underclocking affects some ATI cards/users but not others. Those of us with this issue are only getting around 50% performance out of our GPU's and it's no wonder our framerates struggle to hit two digits!
