Still there with Cat 11.4 drivers.

Groan.

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.

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.

Oh, I almost forgot - I don't have the blue line.

Comprehensive tests!

You don't have the blue lines because you have an Nvidia card. They seem to be a special feature only available to ATi users.

Cheers,

Nick

PS - what utility did you use to produce the plot of CPU/GPU load?

[Flanker35M]

S!

No worries Gunny Happens to all of us. I have Tessellation Off all the time as I do not play games that have it so basically EVE Online, World Of Tanks and IL-2:CoD

I noted that I get less stutter if I set Building amount to Unlimited. Then they are all already on map thus no loading or popping up. Only thing is the LOD on them..with low setting they are like brown boxes and turn to houses within a radius of your plane(like in old IL-2) and that can cause stutter. Again if you set Very High detail to buildings sure no brownie huts but has an impact on FPS.

For me most stutter is caused by SSAO. With it off I have a lot smoother experience with minimal effect on image. Really hard to tell the difference. FPS hit is 10-20fps and that can be a lot in certain scenarios.

Also shadows cause some of the stutter as they seem to have at least 2 LOD's. One farther away and when you are close(within the "sphere of LOD") they turn more solid and less flickery. Shadows also have this strange anomaly that they "stretch" at certain angles and look like lines. So clearly something could be done to shadows, be it total rework or more options.

Trees have same, farther away they look different and when again closer get more detailed. Gotta say I liked IL-2 original Forest=3 more than this and had basically NO effect on FPS. Actually was better than Forest=1-2. I use trees at Very High as I get less stutter with them that way.

Grass. I find it the most useless feature and have it off. Sure it will add something when taking screenies from ground etc. but when flying just a resource strain IMO adding nothing to the experience as the grass appears also within this "sphere of LOD" around the plane.

I wish Luthier would get in contact with AMD, at least their Driver Boss is on Twitter and for sure would be interested to get CoD to run on AMD hardware well. IMO flight sim genre is so small that favoring one brand is like shooting oneself in the leg by leaving out some players due certain features etc. I really do not care if a shooter game is optimized for one or another brand, I do not play them

Anyways, back to testing again this weekend. Testing is the only thing I do with CoD as it offers very little for single player. But a good tool for testing

Hey Gunny,

Thanks for the extensive testing you have done, very interesting. (also whoever said you don´t suffer from the blue lines because you have an nvidia card should have his/her eyes checked). It would be interesting to know what settings you run your tests at graphic wise (everything high, mid, low, buildings unlimited etc)


@GOZR Apart from the blue lines that is a gorgeous screenie, would you mind posting your system specs and graphic settings (especially AA, AF etc and whether you override them or not in CCC) you took the screenie at?


So far it seems not all ATI cards suffer from the three blue lines bug, older Catalyst drivers seem to have helped some but there are people running the latest drivers who also not suffer from this annoying bug, maybe it has something to do with the VBios version or anything but that is just a wild guess.

Only solution that works to solve the blue lines on the horizon bug in all cases is running the game in DX9 but that negatively impacts fps for me for some reason.

On another note, my best results to get anti-aliasing working somewhat decent have been to set them to enhance application settings in CCC and 8x in CoD (although that seems to make little difference from running it at 2 times)
