PS5 emulator KyTyPS5 boots Demon’s Souls, then leaps to 30 FPS in days

KyTyPS5 became the first PS5 emulator to show in-game footage of Bluepoint's Demon's Souls Remake, and performance reportedly jumped from 1 FPS to 30 FPS within a week.

An early PS5 emulator called KyTyPS5 has managed to boot Bluepoint's Demon's Souls Remake and run it well past the character creation screen, producing the first in-game footage anyone has captured of a current-generation PlayStation exclusive on PC. Within days, according to separate reports, its performance went from unplayable to something approaching thirty frames a second.

PS5 emulation has lagged well behind the PS3 and PS4 scenes for obvious reasons: the hardware is newer, better documented emulators like shadPS4 have had years to mature on the previous generation, and Sony's current architecture is a much bigger target. Until recently, the state of the art was SharpEmu, which DSOGaming reported could get Demon's Souls as far as the character creation menu back in July 2026. KyTyPS5, described as SharpEmu's biggest rival, has now gone further, launching the game and rendering actual gameplay, with what DSOGaming's John Papadopoulos calls full graphics and no major visual issues. The site also says KyTyPS5 can launch and run Grand Theft Auto 5, a heavier and more established 3D title, which it calls utterly impressive given the emulator's age.

None of this was fast. On a Ryzen 7 9800X3D paired with an RTX 4080, about as strong a gaming PC as you can currently buy, Demon's Souls Remake ran at 1 frame per second when the footage first surfaced, hence the sped-up clip that did the rounds on social media.

Why the frame rate numbers do not quite agree

What happened next is where the reporting gets messier. Videocardz reports that the latest build pushes the game up to 30 FPS, though it stresses that build is not public and frame pacing still needs work. Wccftech's headline repeats the same 30 FPS figure as a milestone. But TweakTown's account tells a more modest story: it puts the actual measured improvement at 10 to 18 FPS, an increase it calculates at roughly 800 percent over the original 1 to 2 FPS, and quotes KyTyPS5's developers as saying 30 FPS might be achievable by the end of 2026 if progress continues, framing it as a target rather than something already reached. So take your pick: either the emulator has already hit 30 FPS, or that is still a goal for later this year. The sources do not agree, and none of them link to independent benchmarking to settle it.

What else is still shaky

TweakTown also reports that Astro Bot is now running at around 11 FPS, apparently the first time footage of it in motion has appeared, and that GTA 5 remains playable to varying degrees. That would make three notable PS5 titles technically running on PC, none of them smoothly. The site notes that some people online have suggested AI-assisted code is behind the sudden jump in performance, but adds there is nothing confirming that either way, so treat it as speculation rather than fact.

None of this makes Demon's Souls playable in any normal sense yet, and the developers themselves are reportedly cautious about how far this can be extrapolated. DSOGaming is sceptical of claims doing the rounds that KyTyPS5 could run GTA 6 before its PC release, arguing it would be a minor miracle to have Demon's Souls or GTA 5 running at full speed by then, let alone a newer game. For anyone hoping to play PS5 exclusives on PC soon, the honest answer is: not yet, and probably not for a while, but the gap is visibly closing faster than expected.
