PS3 emulator RPCS3 can now play Demon's Souls at 60FPS thanks to a patch

By - | Views: 22,390

RPCS3 for emulating the PlayStation 3 continues advancing quickly! A new blog post is up showing off a patch that enables you to play Demon's Souls at 60FPS and 4K.

The patch simply changes the amount of time that’s advanced each frame from 33.3ms to 16.7ms. Since the patch is meant to be used with Vblank at 120 which doubles the max framerate, this lets us get a correct game speed at 60FPS. After that, it is then necessary to set Clocks scale to 200 to re-enable the games internal frameskipping at 60FPS, without which you will drop game speed every time your computer can’t hold 60FPS. I’ve also included another line that’s commented out by default (has the symbol # at the start of the line) which sets the timestep to 8.3 ms. This is meant to be used with Vblank at 240 and Clocks scale at 400 for proper gamespeed at 120FPS.

This is some seriously impressive stuff, amazing to see that RPCS3 can run so well. Have a look at their new video to show it off:

Want to get going? The steps needed are included below:

  1. First of all, you’ll need the EU or US disc version of Demon’s Souls. Only the disc versions will currently work.
  2. Next, you’ll need to right click on Demon’s Souls in the game list and click Configure.
    On the CPU tab, ensure that SPU block size is set to Safe (which is the default setting).
    On the GPU tab, ensure that Write color buffers is enabled and the Renderer is set to Vulkan.
    Once the above changes are made, hit Save and you’ll be back to the game list.
  3. Right click on Demon’s Souls again and click on “Open custom config folder” and open the corresponding config file. In This file you will need to set:
    Clocks scale: 200
    Vblank Rate: 120
    Log: {sceNp: Fatal}
    Please note that all the above options are case sensitive.
  4. Finally, download the patch here and place it in your RPCS3 folder. If you are on Linux, then place it in ~/.config/rpcs3/.

As always, emulation remains as a vital part of gaming's history. Not just so we don't lose access to tons of older games many years later when a developer moves on, but so we can play them often better than the developer was able to run them on the system it was originally designed for.

Quoting: slaapliedjeI actually bought one of the listed Blu-ray drives so that I could rip my own PS3 games. It's a long process and I'd only recommend doing it for those PS3 exclusive titles out there. Like I ripped Red Dead Redemption so I could play it on my PC. Then again it was random how it'd load with the version of RPCS3 that I was using, so decided to just fix the laser in my fat PS3 :P

It would be interesting to have your feedback about the process, what softwares did you use, difficulties you encountered etc.
Sadly my Blu-ray drive is apparently not compatible to dumping PS3 discs.

For now I only did one mitigated test with a pirated game but of course I intend to buy a compatible drive and some PS3 discs to dumping them myself in the future.
I'm particularly waiting for this goal/feature "Support booting from original game discs." will be quite useful IMHO.
https://www.amazon.com/gp/product/B00DWFPDJI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 is the drive I'm using. I'll rip a game tonight and write up a howto.

Yeah, even if that option of booting from an original is there, you'd still need a drive that can read the disks. But it would certainly save the time and hard disk space if you could run it straight from the drive.

Load times might be slower though.

Not necessarily a howto, simply having your detailed feedback.
But thanks though! :)

A bit off topic but speaking of dumping games, I tried to do it with my PS1 CDs and it failed (the resulting image didn't run on my emulator). I was thinking of retry that... It seems the majority of tools to do it are on Windows.
Yeah, I think I used IMG Burn on Windows for the PS3 games. Gonna see what I can use on Linux to copy games.

Quoting: elmapulthe game is running on linux? you forgot to mention that... some times an emulator isnt running as fast on linux as it is on windows.
in some cases the linux build dont even compile, sigh.
example:
https://www.youtube.com/watch?v=ka6C7pDg3vA

but you know what would be cool? if we forget stupid projects like atari vcs that dont have any chance to compete against the likes of ps4(and 5), xbox one(and scarlet) and nintendo switch(or whetever they come up after) and instead focus on making sure that linux is the best platform in terms of breaking exclusivity (funding projects like this, more than the windows folks do, making sure we are their priority)

Spec wise, the Atari VCS isn't far off the PS4 (assuming the specs are legit). Will it compete with the PS4/5? Probably not because Nutari (as some have not so fondly referred to them as) doesn't have oodles of money like Sony does. But the AMD hardware they're using is more powerful than say a Switch is. In fact the Switch isn't all that powerful at all, the only thing that makes it cool is the form factor (portable plus dockable). It's an nVidia Tegra X1, which was released in 2015.

you forgot that nintendo have exclusive games.
and so does sony.
by the time atari launch their console, sony will anounce ps5 and everybody will save money for it.

i know its not trying to compete with ms,sony and nintendo, but the question is, who gonna buy it? aside from linux fanboys and people who fell nostalgy for atari?

People who wanted Steam Machines? :P

Switch has very few exclusives. I have a Switch, but none of the exclusives have really kept my attention. Breath of the Wild was decent, but I'm so used to other open world games, that it was infuriating to me that you can't actually craft items. I stopped playing it a long while ago.

But if you'd noticed what I said, it's going to be the software library that matters. The funny thing is everyone keeps saying that it's nothing more than a raspberry pi that costs too much, and that's not quite true. But yeah if there is no software for it, who cares? Or if there is no software that you can't just run on a cheap Linux box, who cares. Only thing it has going for it above that is probably the size, it still is pretty difficult to build your own PC that is console sized and not have severe heat issues, or bad performance.

So I forgot an important step in getting the game to the computer. You have to decrypt it, and while it SAYS the ps3-disc-dumper supports Linux, I don't really see how to compile it, or use it at all.

Plus the appimage of RPCS3 uses an outdated version of OpenSSL so a lot of features don't work. It should upgrade to 1.1.0.

That one seemed to work. At least under Manjaro. Working on getting the gamepad working.
slaapliedje Aug 18, 2019
Under Manjaro, install libray-git, and rpcs3-bin. Though rpcs3-bin doesn't pull in the vulkan libraries, so I ended up trying to build rpc3-git, but that build didn't work, but it did pull in the right libs.

But after that, I ripped Untold Legends: Dark Kingdom and played it for many hours last night, performance was great, but not sure if it was the game that is glitchy or what, but there were points where I'd get stuck in something and the camera would freak out.

But ultimately, very playable under Linux. Granted, last time I tried Red Dead Redemption in Linux, it was random whether it'd work or not.

nintendo has just the most famous exclusives and some of the most famous franchises ever.
plus its the only way to play good games on the god (aside from a few android ports, all android have is gambling games) so in an certain way, all switch games are "exclusives" they are on mobility

Yeah, was kind of irritated that Marvel Ultimate Alliance 3 was exclusive to the Switch. That and I prefer the artistic style of the previous 2. Still should spend more time playing it.

You're right though, the mobility and docking capability of the Switch is what makes it awesome. I bought Civilization VI for it so I could play it on the road.
