Basically before the ps4 pro got downclocked to standard ps4 speeds when running non pro-patched ps4 games. The new 4.50 firmware will bring boost mode option which allows the ps4 pro to keep its clock speeds running non pro-patched games. Which naturally improves the frame rate and load times. And these videos rolling out are proof that it works very well. The terrible performance in TEW for example seems completely eliminated.
