Even without FAR the port is honestly still better than most of Japan's efforts. The problems mostly consist of minor bugs (like the full screen resolution bug), and stupid oversights (the cutscene stutter).
On the flipside, they put actual work into a full PC version with arbitrary resolutions, rebindable keys, full support of MSAA, and performance which is on par with the PS4 version on equivalent hardware and scales very well on more powerful machines.
An official patch fixing those bugs should be coming soon, but FAR fixes them so it is really no big deal.
