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

http://game.amd.com/us-en/drivers_catalyst.aspx

When running IL-2 1946 or any version before 1946, make sure you tell IL-2 your running an ATI card first in IL-2 Setup and then close it. Open IL-2 set-up again and 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.

Current DX10 cards don't have fixed function pipelines (fixed shaders), they're programmable so when you run IL-2, which has a graphics engine that it 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 in full swing.
Thanx for the suggestions, I am at work right now, so will try it when I get back home. But why do I need to uninstall my driver if I already have the 9.4 verison? I thought I maybe needed to try the driver that came with the card just to test? I will try what you suggested anyway. I had no graphicbugs when I ran the sim with the Nvidia card, so it must be poor Open GL support by ATI. My card says it should handle Open GL 2.1 so something is odd anyway. I have no problems with other games except Battlefield 2 and some shadows that are not right.

Using Driver Sweeper will remove all driver files. Some times when installing new drivers over old ones the files don't copy over correctly. Driver Sweeper makes sure no old files are left behind before you install the new driver.

I don't know about nVidia/ATI having better OpenGL support than the other, they both should be able to handle API calls. It's thier implimentation that may be different. Since other OpenGL games and apps I use don't suffer from the same artifact problems, I'm putting it down to the current IL-2 graphics engine not being compatible with the newer cards, not the other way round.

Either way SoW will change that.

Tested tonight with cleaning the drivers. Installed 9.4. Still errors. Then I turned off overclocking and no errors so far. Didn´t had the time to test long, but flew 10-15 minutes without a bug. Only bug is the purple flash inside the cockpit like a reflection from the muzzle flash, and sometimes when my bullets hit enemy, sometime I see odd colours, but this is not annoying like the other errors where! Thanx for the help.

Hi Kaptein, to solve the purple muzzle flash issue go into "IL-2 setup" which can be found down below your confi file, then uncheck "use vertex arrays" and the other vertex arrays box which I don't recall the name of. It will be easy enough to locate though as there are only two vertex arrays boxes. This will fix the problem.........But occasionally I too get a "rainbow burst" of colours, when firing guns.....Not sure how to fix this but it doesn't happen too often.

EDIT: The second box option is "Vertex array extension", both can be found in the "video" part second from top left.

Hi Wolf, I have seen similar on my 4870X2. What is your driver version and can you post your catalyst control centre 3d settings? Your confi would be helpful too. I solved it by disabling catalyst AI. As mentioned above also the vertex arrays boxes in setup. I have no idea if that is related too, but now I have no problem. Don't ask me why, but it worked on my rig.

This is what I use, which is almost trouble free.

AA 4X (Box filter)
AF 2X
Catalyst AI DISABLED
MipMap High quality
V refresh ON
Enable adaptive antialiasing ON quality (minimum)
Triple buffering on.
Catalyst version 9.4

Your IL2 video setup would be helpful in addition.

Cheers.
