The first thing that people notice is fidelity, says Steven. Its running in 1080p, whereas the last game was running in 720p that immediately makes a difference. The particle resolution had to be very low [on PS3], but because weve got loads more memory [now] we can have higher particle resolutions. More HDR lighting gives lots more range in the type of light we have in this level; both the amount of post-processing effects, and the quality of these effects. Thats the kind of thing people notice when looking at the difference between PS3 and PS4. The games look prettier."
