Finally the patch has improved the frame rate problems, also I've noticed that the water seems to have gotten a graphical improvement. It looks more natural now which is a big plus, one of the most annoying things was the micro stutter on horse back and in general, which has fixed. Some people said the patch got rid of fog in the bog region, fog is still there from what I've experienced, also there's hardly any noticeable fps drops.
Very happy so far with the patch, though the ps4 version doesn't have blood stains on the character nor did they add the button function to hide/show the HUD.
Since most of the issues are being fixed, I hope they consider adding screen filter option to change the colour pallette of the game, from black and white, sepia, cold, realistic and vivid. Also multiple camera options, like behind the shoulder view, zoomed out etc.
