When I setup the sim to use both options to 1 a black box is flashing on bottom left corner inside the cockpit.
use3renders=1 and hardwareshaders=1

I tested with 4.08m version and all 5 versions 4.09bm dlls set that appear in this thread.

Do the new DLL files change any system files in Windows when the game with the new DLL runs?

These are the graphics dll's for IL2 only.

It will not affect windows file system as they are installed into the IL2 directory.

I see. Thanks!

Includes march DLL

If your games running fine then you dont need to try these at all.
