hey mangaroca...in case you havent done it already, try to delete the ubisoft logo(the intro video) of the game...many users with ati cards have a considerable performance increase by deleting the file, which is stored in your steam folder:steam/steamapps/common/il-2 sturmovik cliffs of dover/parts/core/GUI......there is a file called logo, just delete it and you may see a way better performing game.
