I have spent 6 hours researching and making every change possible to my computer, internet, game settings, etc. I still have lost frame rates, sound and graphics stuttering and overall poor performance. This has all been since patch 8.1.5.
I am not the only one.
At this point, someone needs to be honest and tell us what the issue is and whether there is a time frame to repair it.
I think it has something to do with Battlenet because all Blizzard games (WoW and Overwatch) are having issues whereas my other games are not.
