This is getting absurd. I can't believe we can emulate Playstation 3 and Switch to some degree and now even Playstation 5 is attempted on the Deck. Before the Deck came out, I only expected to play indie games and older AAA games on the device. I'm literally flabbergasted right now, at the prospect of playing at least one PS5 game on the Deck. And because of the technical similarities of the systems, it's not even just a wishful thinking. Guys, am I getting crazy?

I mean it was 0.6FPS... That's 100x slower than realtime. It's great PS5 emulation is making strides, but you wont be playing anything on the deck...
We’re also talking about a ~2 Tflops GPU in the Deck vs the PS5’s 10, right? And half the CPU, being generous.
I’m not sure it’s even theoretically practical on the deck, for all but the absolute lightest of games.
Has there ever been a case of emulation working with less compute than the original platform? I can’t think of any. But with the pricing in 2026+ that’s kinda the situation for many gamers.

That would be a valid concern if we emulated the entire CPU on a different CPU. But in fact the CPU type is the same on PS5 and Deck (and your desktop PC). That means it does not need to emulate the entire CPU. From: https://github.com/sharpemu/sharpemu
Executing native CPU instructions
Native CPU instruction execution doesn't guarantee 1:1 throughput, let alone account for the fact that the PS5 has over double the raw power of a Steam Deck.
Translating API calls from the guest software to the host's equivalent isn't free, either. If the emulator uses hardware virtualization, you can also add the extra cycles spent every time the guest needs to perform a hypervisor call.
In a decade, maybe the IPC gains would be enough for something with fewer cores and lesser clock speeds to be able to do the equivalent work of a PS5. Right now? With a Steam Deck? Good luck running anything more intensive than an indie title at full speed.
I don't think anyone said or expect AAA games running at full speed over PS5 emulation on the Steam Deck. Nobody said that.
But even if you set engineering concerns aside, and Sony makes a the Steam deck PS5 native themself, the gulf is still large.
We're strictly talking about games that are more-or-less trivial for a PS5 to run.
I'm not trying to rag on the Deck, but that's just what the specifications dictate.
That's my point. I don't know what else to say and what you think I'm saying. No one asks for AAA PS5 games to run at 60 fps on Steam Deck through emulation... Can't I be happy just to run ANY PS5 game on the Deck? That alone would be enough, because that proofs so much alone. My point was, we can expect PS5 games to run soon. That was my reply to the response that we cannot expect anything anytime soon.
Fair enough. This is true, apologies for being so hostile.
I'm pretty stoked about PS5 emulation in the future too, though honestly I have a pile of other console games I should have, but have not tried to, emulate yet.
Your point is we can expect PS5 games to run soon on the steam deck.
Their point is that we cannot expect ps5 games to run at any playable framerate, maybe ever, due to serious hardware hurdles.
Not AAA games, any games. You disagree on a key point there, and they were just trying to explain why they disagree with you.
Did you read the comment I'm responding to? Not everyone has the same argument, as there are different people responding with different. Some say it will not happen with any game, others say it will only happen with trivial games. And I explain why that may happen sooner than you think.

So clearly it is not about any games.
I suppose an aside, why would you emulate those games when they are available on PC anyway?
Is this a general question why someone would want to emulate the games? It's mostly about preservation. In example I also play the original Super Nintendo games on a good emulator of my choice, rather than the official versions from Steam, because I like that more. From the Steam Decks perspective, I'm more interested into the technical perspective that this is even possible. Even if we just play small indie games on it. It would mean we don't need monstrous PCs after all, because developers try to make it run on small handhelds.
No, my question was, why would you want to emulate low demand ps5 games which aren't even ps5 exclusives?
There's only like five games that are actually ps5 exclusive. All the other games are available other ways which would be better than emulation on a Steam deck, like just native pc versions for the vast majority.
That's not my point as explained. Its being even possible to emulate PS5 games on the Deck that is exciting for me, regardless of which game it is. I couldn't care less of which game I emulate on the Deck or if its available on PC already. It's not for practical reasons, if that is what is confusing to you with my replies. I'm being excited that any PS5 game could be emulated on the Deck, which has lot of implications that is important to me.
I did say my question was an aside.
I know RPCS3 saw a lot of benefits from avx512, doubt it was to the point of running quicker than the original - but I could see dedicated silicon being the reason negative overhead emulation exists.
Yeah, the PS3 was weird. It wasn’t just a “different ISA” like the Xbox 360, the PS3’s processor was a completely different programming paradigm.
I haven’t kept up, but it makes sense that AVX512 helps. That brings desktop CPUs closer to “vector processors” like cell.
Ehm yeah that means they improving. Every emulator started with 0.6FPS. Who says I won't be playing anything from PS5 on the Deck? The PS5 has a x86_64 processor (which can play native Steam games through Linux BTW). This means there is less to emulate and its not like PS3 where it need exponential more power to develop, optimize and run it. The PS5 emulation scene did make huge progress in only a few weeks, therefore your projection with those numbers are meaningless at the moment.
From a technical standpoint, this is fantastic. The Steam Deck is not terribly powerful in the grand scheme of things. The fact that it runs at all is great, and signals that PS5 emulation on PC is actually pretty far along.
What games are worth emulating? It's been a shit generation.
Plenty of decent stuff, but a lot of it came to PC already until sales collapsed due to PSN fuckery, and the fact that nobody can afford gaming hardware any more.
Demon's Souls remake. Astrobot. Gran Turismo 7 (although plenty of alternatives to that).
So look forward to emulating those in 10 years time when you swap a kidney for an Intel Megawank and a Nvidia 9090.
I'll be buying the AMD Megawank and 9900 XTX, thank you very much.
You mean you don't want to play remakes of PS4 games?
GoW, Ghosts of Japan, Horizon, Spidermen and definitely Astro Bot. I think there are a couple more.
Absolutely shit generation, I wont buy a playstation again.
God of War, Horizon and Spiderman are all on PC already.
But none of the sequels will be unfortunately.
All properties listed sequels are on steam too.
They're referring to future sequels, but we'll see how long that exclusivity actually lasts. Almost all of the big games come to PC eventually.
Sony said they won’t port new games to PC anymore.
They did say that. I'm saying we'll see how long that actually lasts. They still need games good enough to be system sellers and TBH I don't think Wolverine's got the juice. They'll go back on what they've said like they've done in the past. Being a patient gamer is going to pay off in the end.
Horizon and Spider-Man are on PC. no need for a ps5 to play them
Unfortunately astro bot would require an $80 controller :(
It's the only game I wanna play. Is it playable now?
Why? Do the triggers and touch not map to steam controller
I don't know
There's more, but not many exclusives
Astro Bot and Demon's Souls Remake. That is it.
There are like a whole 3 games that are decent and Sony doesn’t want us to play anywhere else. Irking them just for that is enough reason.
Jokes on them, I grew up playing "Frontier: Elite II" on an stock Amiga 500. My reactions peak at 0.6FPS! 🎖️
Every time I hear someone complaining about how they can't get 60fps or 120hz or whatever at 4k on some game, I think back to how I had to shrink the screen to like 1/2 of 320x200 to get 10fps on Doom in 1993
unplayable performance
It depends what you're playing. 0.6fps is fine for chess.
The input latency would probably make even chess feel bad to play
True, but I don't think we're talking about the exclusive hot PS5 release of Chess Simulator '27
I think the deck is a stretch, it’s great at what it does but I can’t see it emulating a ps5. Especially given the lack of graphical options. You are however very correct in assuming that is possible. Ps5 uses a standard architecture set based off AMD chipsets. I personally think the hardest thing to emulate would be the memory management swaps. If I recall correctly, Sony and AMD worked closely to make something akin to a complex resizable BAR and allowing quicker swaps between hdd/ram/vram.
