3/4/14 Still having the issue, it usually happens in local chat, ive been wondering if it is more related to scripts communicating in the background, i can get a steadily slowing effect when i am in personal IM's but Nearby chat will rappidly bog FPS down to an unusable level, I have a decent computer with dual Radion 7850's and it should be able to handle things. the interface layer just seems to be bogging everything down.
