Mac FPS Bug Update
I have noticed that not only is it the sound that has been affecting my mac but there must be problems in some visuals. I think that this is rooting back to 6.6 because before that I was playing fine at 60+ fps and now I get an average of 45/50 fps. This problem isn't huge for now since I keep sounds at a low volume graphics at low/very low but take note that before 6.6 I was completely fine with medium/high settings without shadows. Anyways hope a rioter reads this and feeds it back to the teams trying to work on a fix.
P.S. Could you put the issue in the client's implemented service status so that we know that a fix isn't available yet and people don't get confused and mad.
