Interesting find! Its good to know there may be a work around. I don't use ATI cards, so I don't have any way to test and fiddle, but I'll certainly add this to my personal knowledge base. I really wonder if the mods read these posts to monitor trends and pass the info to the dev team. Finding a specific setting that fixes an issue as common as the frequent black shroud crashes is the sort of thing that could seriously help them nail down errors in the coding.
