ATI blue stripes

[Orpheus]

Thanks for the info, I already run GPU-Z so it was easy to check. Tbh as I've not had any issues with the recent 11.4 drivers I'll have to assume they're fine! If only solving this underclocking problem was easier!!

Orpheus,

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!

I just edited the thread above where I posted what I thought were my best settings.

After 3 rounds of confirming tests - I've found that Tessellation at 64X instead of OFF makes a significant differenence in stuttering and minimum FPS. 15 fps difference in multiple tests.

I have also found that Application AA from CoD doesn't do much past 2X - however at 8XAA the frame rate and stuttering are much better.

I'll post more in a seperate thread when I get home tonight. Gotta run.

Are you saying that Tesselation enabled INCREASES your FPS? The 5870 is one of the earliest cards with DX11 and Tesselation features, and it's Tesselation performance is much worse than Nvidia's 480/580 so I guess that just shows us again that the engine can't utilize graphics cards properly at all. Especially since CoD doesn't even run DX11, so having Tesselation enabled shouldn't do jack all for your performance. Atleast not increase it.

Run a Tesselation test at Unigine Heaven and you'll see what I mean.

Still there with Cat 11.4 drivers.

Groan.

Yes - that's what the data says. Edit: No, I was mistaken about tessellation. Data interpreted incorrectly. Background Application, ATITrayTools source of performance difference.

The software is using the engine differently.

I'll post my data in a new thread as soon as I get home.

Look at the AA scaling I mentioned.

Here the lines same here..Cat 11.4 drivers.
