While Final Fantasy VII Remake runs at 30 FPS on PS4, it is now possible to bump the frame rate to 60 FPS with this unofficial patch.
Final Fantasy VII Remake runs at 30 FPS on the PS4. It was confirmed that the PS5 version will support 60 FPS but this doesn’t apply to the PS4 version. A modder has now released a patch to brute force the game and makes it run at 60 FPS on the PS4. This is achieved by downgrading the resolution to 720p on the base PS4. If you have PS4 Pro, you can tweak it to run at a higher resoution.
The unofficial patch can only be installed on a modded PS4. This means you need to have a console that can be exploited and modded to run homebrew. Under the current limitations, this is only possible on PS4 which has a firmware version 7.55 or below.
If you are interested in patching the game to run at 60 FPS, you can grab the files from here. You will need to make a slight tweak in the .ini file if you want to run the game at a higher resolution, however, it is best to try it only if you have a PS4 Pro.
Just like Final Fantasy VII Remake, it was possible to brute force Bloodborne and make it run at 60 FPS on a modded PS4. This method also relied on dropping the resolution all the way down to 720p but it was the only way to play the game at a higher frame rate.
