Let me start off by saying that otherwise, the game runs fine. I can run at almost every setting at Ultra High except for shaders (and thus shadows) and AA. However, anytime there is any smoke/dust on my screen (such as from grenadiers clearing a building, a nuke going off, etc.) the game slows down to a crawl. However, even if I turn everything down low, these objects still retain their high detail (and thus laggy) settings. Is there any way to manually change these by editing a file or something?
