PS3 emulator RPCS3 shows off new feature that lets you uncap the framerate in certain titles



As the years go by, PlayStation 3 emulation has become more and more viable, as the hardworking team behind the PS3 emulator RPCS3 continues to make major updates and breakthroughs. The most recent addition to the emulator is a WIP feature that allows users to remove the framerate cap for certain games, causing them to run at a smoother framerate than they did on original hardware. It's important to note that this won't affect every game in the PS3's library, though there are a few games that already make use of this removed fps limit without doubling the internal game speed. In the above video test, we can see Ni no Kuni, Tony Hawk Project 8, Sega Rally, Batman Arkham Asylum, Shadow of the Colossus, and Ferrari Challenge running at or around 60fps; a higher framerate than how they played on the PS3.

Three ways to get double fps cap (game dependant):
  • Double Clocks Scale value.
  • Double Vblank Rate.
  • Double Vblank Rate and halve Clocks Scale.
NOTE: it's possible that a game may rely only on timers and not vblank for frame capping, changing time scale in this case will affect the speed of playability as well.
Or even use another method for fps capping unsupported at the moment.

According to others who have tried out recent builds of RPCS3, Final Fantasy XIII, Ratchet and Clank: Into the Nexus, and perhaps most shockingly of them all, Red Dead Redemption, work too, though some of these games still aren't fully playable even at 30fps yet. The framerate override hasn't been officially added into the feature list for main builds, but if you're curious enough to want to test it out yourself, you can do so by using one of the master builds of the emulator.

To enable it, you'll have to edit each game's configuration file (that you want to try it with) at /config/custom_configs/. Look for the line VBlank Rate: 60, and replace 60 with an integer multiple of it, e.g. 120. If the game was originally 30 fps capped, this will raise the cap to 60 fps (to it's double).

This feature is still in heavy research and will probably improve even further, hopefully making even more games compatible and uncapped

This shit made things a little wet downstairs for yours truly when I saw it on Reddit the other day. Imagine, if Sega, for some boneheaded reason decided to not release the remasters of Yakuza 3-5 out West, if this works with those games' OG releases on PS3, people would be able to play the games in 60 fps...with the visual problems of the PS3 versions' limited draw distance and aliasing, not to mention artifacts of holding over old translations from the arrogant motherfucker that is the PS2 version of Yakuza 1, but alas, it would be an option as I could see Sega re-releasing Yakuza 6 on to Steam before the remasters' localizations and PC ports, though we'll see. Yakuza 5, once optimized, won't be a performance nightmare when a lot of enemies and other things are happening all at once on screen!

Can sb pls explain why it is not possible to make N64 emulators increase the framerate?

Tough some patches are available for some games, the original hardware used a lot of tricks to even run the games at their native frame rate, and a lot of code was dependent on how the n64 behaves, and said behavior is hard to emulate until today, even with powerful machines.

not a fan of ps3 due to it's noise (it was really annoying for me to hear a game console crying the way it did when we launched a game demanding on power)

Never had such an issue. Maybe clean your consoles once in a while or take them out from the enclosed entertainment stand. ;)

Uncapped frame rates huh?
That'something I wasn't expecting.
I wonder how Persona 5 would benefit from this new WIP feature.
Though I doubt my i7 6700HQ would be able to push any more than 30fps.
