Some players may be experiencing an issue with decreasing frame rates after the 4.8.1 update. The decreased frame rate issue may cause the application’s display to lag when scrolling and in rare cases cause a crash.
We appreciate your patience. Our team is working to have a solution very soon. Please note the frame rate issue will be improved by the small update just released on 5/16/14.
We will continue to provide updates as our team works on resolving this issue.
