It's probably more to use the 'low framerate' trick that PC users can exploit to make the jumping puzzles for the Sightseeing Log much easier, which is rather skirting into dangerous territory here with the ToS.

Either way, it's not going to happen (the ability to change framerates on the PC are to compensate for those who have older video cards/system configurations, where as the PS4 has a pretty set in stone configuration hardware and software wise so it has no technical need for this). So I'm sorry to say that will not be happening.
