ATI Radeon HD 4670 and graphic anomalies with IL-2 1946

[Codex]

Try this...

Uninstall the ATI drivers via Control Panel.

Download and install Drive Sweeper and use it to clean all traces of previous ATI driver files.

Once you've cleared the driver files, restart the PC. (Note: Your system will revert back to std VGA drivers after restart.)

After the restart, install Cat Driver 9.4

When running IL-2 1946 or any version before 1946, open IL-2 setup and make sure you tell IL-2 your running an ATI card, then close IL-2 setup. Open setup again and then select "Custom" to tweak the settings. Ensure you disable Vertex Array and Vertex Array Ext as this can cause artefacts or textures to have blue tinge. Also I recomend experimenting with CAT driver settings by allowing the application to control AA and AF. I always set CAT AI to standard when flying as setting it to advanced will result in freaky corruptions.

Note: Current DX10 (nVidia 8000 / ATI 3000) cards don't have fixed function pipelines (fixed shaders), they're programmable, so when you run IL-2, which has a graphics engine that is pre DX10/OpenGL 2.0 era, your card drivers have to "emulate" a fixed function pipeline, as such there will be little bugs that unfortunately you'll just have to live with. Its unlikely that the IL-2 graphics engine will get an update with custom shader code considering SoW development is in full swing.
