Since the last patch I have been experiencing what seems to be a memory leak issue when playing. Usually my first game will run flawlessly, with maybe a minor hitch here and there. But if I queue for another game without exiting the client then my performance in the second game vastly reduces from 60fps to 30-40fps. Only fix is restarting the client. Issue also seems to be exacerbated by alt-tabbing too, like tabbing out will cause the fps drops to worsen.
