Just did 25 man OS. No disconnects. To think about I did not have vertical sync. unchecked yesterday and earlier today like I thought. Before running this OS, I unchecked it. Ran in windowed mode and no disconnects.
However, I did see very low FPS drops during the raid. But hey I lived and got #2 overall DPS :-)
