Finally, track shaders also receive an upgrade, once again thanks to the clever design of the PS4 Pro hardware. As the developers explained, “packed fp16 ALU operations, which are unique to the PS4 Pro in the console space, offer us a very powerful tool for optimising shaders, allowing us to enhance CU occupancy and reduce overall instruction count.”
For the less tech-savvie, this ultimately means the hardware design naturally lends itself to providing higher-quality environment shaders, allowing the team to give tracks a more finely-detailed overall appearance.
