weirdly yes I agree with this. FPS is hovering around the same numbers as in the closed beta, but the open beta definitely doesn't feel as smooth, mouse movement feels jerky that's for sure. Definitely was the first thing I noticed.
This.
Probably down to servers being more loaded than the closed beta.
I notice this with bf 4 etc. when my connection is pap, the game just doesn't feel right and even the fps can dip.
