Demon’s Souls Remake achieves remarkable framerate on PS5 emulator as progress continues at the speed of light
An early PS5 emulator, KytyPS5, can now run sections of *Demon’s Souls Remake* at around 50 frames per second, with few visible graphical problems or crashes in the footage. The progress is notable because the game is a PS5 exclusive, and advances in emulating it could help developers improve support for other exclusives and preserve PlayStation games on PC.
The footage was captured on an Nvidia RTX 5090, so the results do not yet mean the game is practical to play on typical hardware. Some movement appears sped up, possibly to compensate for lag or slow animations, and wider playability remains a challenge. The article also notes progress with *Astro Bot* and says PS5 emulators have been advancing unusually quickly.
In short
- KytyPS5 runs sections of *Demon’s Souls Remake* at about 50 FPS.
- The footage used a high-end RTX 5090, and the game is not broadly playable yet.
- The progress could help with PS5 game preservation and emulation.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Rapid progress in PS5 emulation could help preserve games that might otherwise remain tied to ageing consoles, while giving developers useful insights into compatibility and performance. The footage suggests that even an early emulator can now run parts of a major exclusive with few visible faults, and continued work may eventually make such games accessible on a wider range of hardware.
The case against
A striking demonstration is not yet evidence of practical, reliable access: it was captured on exceptionally powerful hardware, covers only sections of the game, and may speed up movement to mask performance problems. Emphasising rapid progress could overstate how close the emulator is to a playable experience, when broad compatibility and stable performance remain unresolved.
Explained simply
PS5 emulation is the process of running games designed for the PlayStation 5 console on a PC using specialised software. Whilst emulators exist for older PlayStation generations, the PS5's complex technology has made emulation far more challenging, leaving its exclusive games largely inaccessible on other platforms.
KytyPS5 is one of several projects attempting to create a working PS5 emulator. Such efforts are motivated by game preservation and research into how titles can remain playable across different systems and future hardware.
Emulating the PS5 remains technically demanding. Running games smoothly requires high-end graphics cards and extensive programming work to handle countless hardware details. Practical emulation is currently limited to those with specialised equipment, though development has accelerated significantly.
