As the title suggests I am having problems with a single 5 man team I am running.

I have multiple 5 man teams running with no problems at all, all teams have identical settings. However when i open up and run my Death Knight team it will only ever give 1FPS and causes a lag in windows as well. As soon as I close the windows everything is OK, if I immediately open any other 5 man team I get 60fps across all no problems.

I have deleted the team and renamed it something else and I still have the same problem. I have been using this team with zero changes for many months with no problems and this has just started from nowhere. 4 Slaves always run on lowest settings and master on ultra / Max everything. I have dropped DK Master to lowest and still doesn't help.

If anybody could offer some suggestions that would be brilliant, I'm not very clued up with computers so if you need any extra info, assume I have no idea what you are on about so keep it simple
