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.

Gunny, strange how Tessellation can affect FPS when the game uses none. But you never know how these games work Gotta try that when back at home. Before CoD is patched up good using it just to test my settings and patches. WoT taking too much time

Anyways, fill the feedback form to AMD. It made a difference to IL-2 1946 as well

I was w-r-o-n-g But I hope you'll understand my mistake. I just finished 5 hours of Black Death testing to confirm:

1. Tessellation as expected, had no effect on anything I discovered that I had not taken account of whether or not I had ATI Tray Tools running. So I when I changed the Tesselation setting from OFF to 64X - ATI Tray Tools was running.

2. So I started a long series of tests iterating Tessellation and Disabling ATI Tray Tools and Turning it back on. Here are the results:

8XAA in AP - Tessellation = 64X - ATITrayTools Running
Frames, Time (ms), Min, Max, Avg
8787, 211340, 0, 96, 41.578 2 big pauses
8830, 211417, 7, 95, 41.766 2 stutters
8569, 211280, 0, 94, 40.558 pauses
8043, 211964, 0, 92, 37.945 8 stuttering periods
8578, 211848, 0, 91, 40.491 pauses

8XAA in AP - Tessellation = 64X - ATITrayTools Shutdown
Frames, Time (ms), Min, Max, Avg
9114, 212280, 17, 98, 42.934 Smooth
8994, 212468, 16, 96, 42.331 Smooth
9093, 212634, 17, 96, 42.764 Smooth
9000, 212428, 15, 97, 42.367 Smooth
9007, 212326, 17, 97, 42.421 Smooth

8xAA in AP - Tessellation = OFF - ATITrayTools Shutdown
9012, 212089, 16, 97, 42.492 Smooth
8905, 212175, 17, 93, 41.970 Smooth
8784, 208758, 17, 95, 42.077 boringly smooth
8822, 212061, 16, 93, 41.601 Smooth

8XAA in AP - Tessellation = OFF - ATITrayTool Running
8754, 212337, 0, 96, 41.227 2 large pauses
8892, 212400, 18, 97, 41.864 smooth!
8839, 211994, 14, 93, 41.695 smooth
8414, 212259, 0, 93, 39.640
8614, 212233, 0, 95, 40.587
8605, 212233, 0, 92, 40.545
8562, 212274, 0, 89, 40.335
8688, 212419, 9, 91, 40.900 some jerkyness
8768, 212443, 16, 95, 41.272 smooth
8571, 212186, 0, 95, 40.394

As you can see, ATITrayTools has an effect on the FPS of my system, but in a bit of a random manner. I have no idea why. I have never setup anything in my ATITrayTools except to run the Graph output for the various functions.

In case anyone's interested I conducted these tests in the following manner:

1. Start TrackIR, Thrustmaster Target software and Fraps to simulate real load.
2. Start CoD - select "The Black Death" track and after it loads select Play.
3. Let the first playback proceed until it's ended.
4. Restart "The Black Death" track
5. Start Fraps benchmark 5 seconds into track. This is the point where Bf-110 #3 transitions his tailwheel to cross the centerline of nearfield Bf-110 port propeller hub.
6. Observe each track and note pauses, stutters or micro stutters.
7. Stop benchmark after the Bf-110 dives. Track is 3 mins 40 secs long.
8. Repeat. Organize documentation and files.

Anyway, I feel a little silly about the Tesselation - kind of did when I posted it. But, hopefully I made up for it

I'm still running Cat 11-3, as I wanted to finsh this testing. I'll install 11-4 today and see what happens.

BTW my settings for these test, except where indicated are:

One last thing. Here's a screen capture I did during the earlier testing, obviously when ATITrayTool was active. You can see the cross-core load as the track is being played and you can observe the CPU load (yellow) and most importantly the 5870 GPU load (pink).



At least these settings in Cat 11-3, have my GPU loaded to a greater extent.
