Well, the patch contains a particle system txt file... You need to put it into your Age of Blackpowder: Realm of Revolution module folder. ( C/ProgramFiles/Mount&Blade/Modules/AgeofBlackpowder...) Although the patch won't work that much... Maybe you should look at this thread (you can find a particle system that removes the smoke...): http://forums.taleworlds.com/index.php/topic,73174.0.html
