I had trouble getting vox to work. Once I did the .resetv and relogged vox works better than ever. Crystal clear. 
I can see better in GVs now and can get hits before I die which I couldn't do before. 
My hit % has gone up a couple points since the update. 
The point is I don't think the game has a problem. Too many people play this game with laptops or don't realize that their computer is at the edge of it's ability to run the game smoothly. Then an update comes along and pushes their equipment over edge because of the new demands and it's all the games fault. 
Just because you can run COD with eveything maxed doesn't mean you can do the same with this game. Aces is built different. Everything is run on your computer. COD is run on a server that you log into, so some of the computing load is on the server. Here it all you. So if your computer is just hanging on, an updae can push it over the edge. 
 Not the case in my situation should have enough of everything.
