First of all, I’m talking about tracking arrows. Before the patch it was very hard to find a predator who’s using bow if he didn’t move and was in stealth mode. He was almost able to shoot in your face. Now it’s very easy to find him, because each arrow has a noticeable red “tail” that shows you where it was shot from.
Secondly, it seems they did something with PS4 grafic settings - I mean PS4 players now spot predators as good as “clever” PC players who “smartly” change their graphic settings (I’m talking about shades quality settings and so on). It’s almost impossible to stay invisible after the patch, you can easily spot the Predator from very long distance.
Thirdly, they did something with PS4 hitboxes or autoaim. I mean after the patch almost ALL of the PS4 players suddenly transformed into snipers. Their accuracy increased dramatically. I believe that you can become better player just by playing the game, but I don’t believe so many players could become much better just in 1-2 days right after the patch.
