So this last patch, I noticed that the game is running a lot smoother,and even on the heaviest block full of people, I had almost zero screen lock. In fact it's only locked once, and that was because I pulled up the lookbook. Combat is smooth as well. Even on a screen full of enemies, I haven't had frame rate drops. Overall I don't know what the devs did to fix it, but I greatly appreciate it.
I'm not sure if anyone else is having the same user experience, so I posted this in general to both see if other users had those positive improvements, and to relay my appreciation to the developers via the GM's.
