This patch actually made performance worse for me, it was very smooth before. Did Physx and Fur options come with this patch? They are not in the notes but I notice they have been added to the advanced graphics settings panel. Maybe this causes the issues now since it appears flashbangs and grenades are causing a lot of hiccups.
