i think its 60 fps in the Epic footage because its on Pc and you dont want to advertise Pc games with 30 fps nowadays.
Pro enhanced probably means that its running in a higher resolution like 1440p or the quality of the graphics
is slightly better.
if the base Ps4 is running the game in 30 fps, i doubt that the Pro runs in 60 fps.
i mean thats twice as much. the Pro is not twice as much powerful as the base PS4.
and the worst "enhanced" thing would be, if they just unlock the framerate.
if they just unlock the framerate with a 60 fps target, there is a very high chance
that the Pro can not maintain 100% stable 60 fps and this will result in unstable framerates
like 35, 40, 45 fps and this can feel really really really bad.
a unstable framerate that is constantly changing between 35 and 55 fps can feel WAY worse
than 100% rock solid stable 30 fps.
