What settings should I use in ATI CCC and IL2 setup/conf to get both optimal play and nice graphics, if possible? Now I am using OGL, Max Settings, default conf.ini and I get some random freezes especially on 4.09 Slovakia map.

Try turning the Aanisotropic Filtering to 8x and the Anti Aliasing 8x it increased my FPS to 1000 max avrg 70 on IL2

It keeps freezing and it displays a strange colour dissipation effect similar to motor oil on water. Probably the ATI drivers are not mature yet. With previous X1950 Pro card did not have these problems.

What water-setting do you have and what other settings in the ini-files? Are you sure you run the game with 32 bit color-depth? It would help us to determine what the problem is, if you post your settings listed under "[Render_OpenGL]" from your conf.ini-file.

If somebody has the same card you have, but no such problems, it's likely your settings rather than the drivers.

Besides that: Did you deinstall and reinstall drivers after switching your cards?

Just learnt a tweak to control the idle temps, heard it's toasty on the stock units.

If you make a profile in catalyst after turning on Overdrive( make sure clock and memory settings are correct). You can then go to the file "C:\Users\your computer name\AppData\Local\ATI\ACE\your computer name. XML. the xml file will have the same name as the catalyst profile you saved. right click and hit edit.

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />

Change the value to "manual" and Want value to "65" (% of fan speed)

Save the file then reload your profile in catalyst.

For fellow XP'ers it's under C:\Documents and Settings\"your computer name"\Local Settings\Application Data\ATI\ACE\Profiles.xml

Knocked 10 degrees off idle and 5 off load on here.

Make sure you uninstall the drivers and do a driver sweep

Get the tools from Guru3d.com
also might want to try the 8.7 beta drivers over there too.

I uninstalled the old 8.1 cat drivers using the ATI Uninstall Utility, then installed the latest drivers. I may give it a try with 8.7 beta, thanks a lot for the link.
I will also post some of my conf.ini settings.

Wow did not realized that this would start a NVIDIA vs ATI debate but well...

I used to have an ATI850XT prior to buying a pair of BGF 7900GTX OC cards (on sale BTW). Like most I saw a reduction in picture quality when going to NVIDIA. I now have flicquering that I did not have before. Could be an SLI thing, I'm just not that familiar with NVIDIA's cards. My previous ATI card had no problem running iL2 under open GL and gave a great image (no flickering costline/runways/invisable roads)... Also spotting planes was a lot easier... we all know how this is important LOL

I was thinking of going back to a single 4870 for now and buying a second in the future. So going with a single card could eliminate a lot of the SLI (or Crossfire) related stuff...

I know that this sim is VERY CPU intensive. Hell an OC of 0.2 will give you about 10% more FPS... So to all of you out there overclock those #$%?&*. Mine is overclock up to wasooo as it only have to live for about 6-8 months (new Intel chips are coming with the X58 platform).

So what is it GOOD with iL2 or NOT... its the ONLY game that I play.

Very similar config to mine dflc03, not sure if this might help but try changing all the entries with "NV" to a value of 1 eg:

TexFlags.TextureShaderNV=0

TexFlags.TextureShaderNV=1

Think the zero value is specific to nvidea cards.
