There seems to be a problem with the latest patch that has affected this. Aloe of people a complaining about hit detection aswell. For me I don't seem to have this problem but in close quarters the frame rate drops dramatically. There is a YouTube called westie and he has made a really good detailed video that explains all the issues that are happening since the patch. Definitely check it out as it made things a lot clearer for me and also I'm sure I saw dice is doing a hot fix some time this week so fingers crossed it will go back to how it was.
