Demon’s Souls Remake hits impressive frame rates on PS5 emulator as development advances at a lightning pace

Background: Sony, 2028, and the Move to Preserve PlayStation Games on PC

Sony remains determined to kill physical media for good starting in 2028. People who oppose that idea are working to make all PlayStation games—whether physical or otherwise—preservable on the PC, the one platform where that preservation appears actually possible.

PlayStation exclusives are usually locked to console hardware. Demon's Souls Remake, developed by Bluepoint Games and published by Sony Interactive Entertainment for PlayStation 5 on November 12, 2020, is a crucially important PS5 exclusive. AstroBot, also known as Astro Bot and released for PlayStation 5 on September 6, 2024, is another title now appearing in the same emulator discussion. The article below tracks technical progress, not story events.

Development: KytyPS5 Compresses Years of Emulator Progress into Weeks

Several PlayStation 5 emulators are up and running at the moment. One of them, KytyPS5, is making tremendous progress, jumping from one milestone to the next within weeks. Earlier console emulators often needed years to reach the same stability.

The speed matters because PS5 emulation is not just a brute-force hardware problem. A PS5 game depends on a custom architecture, console-specific timing, and design expectations that do not automatically translate to PC. Multi-platform games tend to progress more smoothly because their PC versions already align with non-PS5 hardware. PS5-only games are harder, because there is no official PC version to use as a reference.

Latest Progress: Demon's Souls Remake Hits 40 to 50 fps on KytyPS5

Players are now getting Demon's Souls Remake to run and play at around 50 FPS on KytyPS5. A shared post from u/Dense_Organization76 in pcmasterrace describes the result as "Demon souls remake 40 to 50 fps on pc emulator KyTyps5".

The framerates look smooth and satisfying. The footage also appears to run without major graphical glitches, and the game does not seem unstable and prone to crashing during these first few segments. Things do seem a little sped up, probably to account for some internal lag and slow-motion animations. That is one of the hurdles the emulator will need to surpass to achieve actual broad playability.

What the RTX 5090 and $5000 GPU Reveal About Hardware Limits

The footage is running on an Nvidia RTX 5090. While KytyPS5 shows a lot of promise, we are still a bit far from the average Joe having the means to take it for a proper spin. Emulators always need the beefiest hardware in their early days, so it is not surprising to see the best GPU on the market used to test everything and iron out any potential problems.

The source coverage appeared first on Destructoid, and its Destructoid Checkpoint newsletter is described as gaming news with a bit of snark. The report calls the development speed astonishing and notes that the writer did not expect to see an actual PS5-only game running this well this soon, "$5000 GPU be damned".

What This Means for Other PS5 Games

The Demon's Souls Remake result is useful because it is not just about one game. Handling a crucially important PS5 exclusive can give emulator developers the tools and understanding necessary to tackle other PS5 exclusives and improve performance across the board. AstroBot is also making some great strides on the emulator, and the next milestone will show whether this momentum can extend to more PS5-only titles.

For readers, the significance is preservation. A PC emulator is not a storefront, not a cloud service, and not a substitute for buying games. It is a technical path to keep access to games that may otherwise be tied to aging consoles or a shrinking physical-media ecosystem. If Sony's 2028 physical media direction moves forward as described, emulator progress becomes more relevant.

Current Stage: A High-End Proof of Concept, Not a Mass-Market Experience

At present, KytyPS5's Demon's Souls Remake milestone is an early, high-end proof of concept. It demonstrates 40 to 50 FPS on Nvidia RTX 5090 hardware, shows smooth early segments, no major graphical glitches, and no obvious crashes in the first few segments. It also exposes the remaining gaps: timing speed-up, broader stability, and accessibility outside elite GPUs.

The timeline now runs from Sony's 2028 physical media goal, to PC-based preservation work, to rapid KytyPS5 milestones, to Demon's Souls Remake at 40 to 50 fps, to AstroBot progress. The current stage is still a $5000 GPU showcase, not a mass-market way to play PlayStation games.
