Thanks to modder illusion0001, a new unofficial patch has been released that will allow you to unlock the frames per second on the Playstation 4 Pro version of Red Dead Redemption 2. This mod still allows for 1080p, but unlocks the FPS to maintain around 50fps instead of the normal 30fps.
For those interested in downloading the mod, you can do so here.
