This is what they tell me when I ask why my character walks insanely slow and gets passed up sprinting by players not sprinting because of the lag issues. Ping is 68, ran benchmark and got above standard score. Obviously not my side but this is as far as they will take it. Basically a really long fk off and suck it up cause forums wont do anything.
