PS5 Emulator KyTyPS5 Pushes Housemarque’s Saros to 20 FPS on RTX 5070 Ti
PlayStation 5 emulation on PC has taken another big step forward. Housemarque’s PS5 exclusive Saros now runs at up to 20 FPS through the KyTyPS5 emulator on a GeForce RTX 5070 Ti, according to a new video report published by GameGPU on November 3, 2026. That is a fourfold jump from the 5 FPS runs recorded only weeks ago, and it continues the fastest progress curve the PS5 emulation scene has ever seen.
If you follow PS5 emulation, this guide covers everything that matters about the new benchmark: the hardware and build used, the month-long progress arc from 1 FPS to 20 FPS, what KyTyPS5 actually is, what 20 FPS really feels like, the setup considerations if you want to experiment, and whether this project is worth your time right now. One important note up front: every figure below comes from the emulator community’s published test videos as reported by GameGPU and DSOGaming. We have not run these builds ourselves, and results vary between builds and configurations.
What the new benchmark shows
User IndependenceBig3178 published a video showing Saros running on PC through KyTyPS5. GameGPU reports the following setup and results:
- Emulator: KyTyPS5 build 0.2.1
- Game: Saros, version 01.005.002, region code PPSA17121
- Test hardware: NVIDIA GeForce RTX 5070 Ti graphics card and an AMD Ryzen 7 9800X3D processor
- Frame rate: 12 to 20 FPS across the demo; 18 to 20 FPS during the opening cutscene, dropping to 12 to 16 FPS in open gameplay with the energy shield active and the futuristic weapon firing
- Visual quality: the game correctly renders 3D models, lighting, and particle effects with no critical graphical artifacts and no crashes
The footage shows the protagonist Arjun regaining consciousness in a destroyed location, delivering story dialogue, and moving into direct gameplay with the interface and tutorial prompts on screen. For an Unreal Engine 5 title running on emulated PS5 system software, that is a remarkable level of correctness.
The progress curve: from 1 FPS to 20 FPS in a month
The jump to 20 FPS looks even more dramatic against the previous Saros milestones reported by GameGPU and DSOGaming this October:
| Date | Test hardware | Emulator build | Saros performance |
|---|---|---|---|
| Oct 9 | RTX 5080 Laptop | 2d6988b-dirty | 1 FPS, game loaded but not playable |
| Oct 10 | RTX 5090 + Ryzen 7 9800X3D | Public build | 3 to 5 FPS, GPU usage 18 to 20 percent, CPU usage 15 to 18 percent |
| Oct 23 | RTX 4080 + Ryzen 7 9800X3D | 7b7f9a7 | 5 to 8 FPS |
| Nov 3 | RTX 5070 Ti + Ryzen 7 9800X3D | 0.2.1 | 12 to 20 FPS |
Notice what the table tells you: a slower GPU in November beats a faster GPU from October. The gains come from emulator development, not from throwing hardware at the problem. That is the signature of an emulation project in its rapid-maturation phase, and it is why GameGPU’s community discussion focused on the pace of development as much as on the raw number.
What 20 FPS actually feels like
It helps to put 20 FPS in context before anyone gets excited about booting the game. Twenty frames per second means each frame stays on screen for 50 milliseconds, compared to about 16.7 milliseconds at 60 FPS. In a slow cutscene that is watchable, which is exactly what the video shows: the opening holds at 18 to 20 FPS because a cutscene is mostly playback. In open gameplay, where the player has to aim, dodge, and react, 12 to 16 FPS means your inputs land with a long delay and motion looks like a fast slideshow.
There is a useful rule of thumb. Below about 24 FPS, most people perceive individual frames rather than continuous motion. Around 30 FPS, slower games start to feel playable, but fast action still feels sluggish. Sixty FPS is where modern action games start to feel right. Twenty FPS sits in the “proof of concept” zone: it proves the game renders and runs, but it is not a playable experience by any standard you would hold a real PC game to.
What KyTyPS5 is
KyTyPS5 is a free and open-source PlayStation 5 emulator written in C++, targeting Windows and Linux with experimental macOS support. The facts we can verify from the project’s public pages:
- It is based on a heavily modified version of Kyty, a 2021 research project, and is licensed under GPL-2.0.
- The project published its source code in mid-July 2026 and has grown to become one of the largest PS5 emulation projects, second only to SharpEmu in community stars according to heldgames’ PS5 emulator survey.
- It can boot 2D games and a selection of 3D games, including titles built with Unreal Engine 4 and 5, Unity, and custom engines.
- It is not affiliated with Sony Interactive Entertainment, and the project does not distribute games or copyrighted system software. You must supply game files you have obtained legally.
Open-source means the code is public and anyone can inspect it or contribute. That is what makes rapid progress possible: developers work on different bottlenecks at once, and every build becomes a public experiment.
Why Saros is a hard target
Two factors make Saros a particularly tough benchmark. First, it is built on Unreal Engine 5, and GameGPU notes that emulator performance on UE5-based projects carries high hardware load even on modern flagships. Second, it is a current-generation exclusive: Returnal, Housemarque’s previous game, eventually came to PC, but DSOGaming’s coverage notes that Saros will most likely stay a PS5 exclusive, which makes emulation the only PC route on the horizon.
The wider scene shows the same trend across other PS5 exclusives. DSOGaming’s October 11 video roundup reported Demon’s Souls Remake running at 40 to 50 FPS and reaching 60 FPS in some areas on KyTyPS5, Marvel’s Wolverine at around 40 FPS, and Astro Bot at 40 to 50 FPS on a high-end PC. Saros is simply the heaviest of the set, and the one improving fastest.
One interesting wrinkle from the community discussion: Nixxes Software, the studio famous for Sony’s PC ports, participated in Saros’s development as a support team for the console version. That has some players speculating about a future PC port, but Sony has announced nothing, and emulation remains the only confirmed path.
Setup considerations before you try anything
If this progress has you curious about experimenting yourself, a few practical points come before anything else. First, check the KyTyPS5 compatibility list and confirm against the latest build, not old videos: builds change behavior between releases, and a game that boots in 0.2.1 may behave differently in whatever comes next. Second, expect uneven results by title. Lighter 2D games and older-engine 3D titles are the realistic starting point; Unreal Engine 5 exclusives like Saros are the far end of the difficulty scale.
Third, keep your hardware expectations grounded. The test hardware here is a GeForce RTX 5070 Ti paired with a Ryzen 7 9800X3D, a high-end 2026 gaming PC, and it still lands at 12 to 20 FPS on the heaviest title. At this stage, emulator updates move the needle more than GPU tiers, as the October to November table proves. Do not buy hardware specifically for PS5 emulation right now. Finally, the legal side is simple: KyTyPS5 ships no copyrighted software, so use only game files you legally own.
What this means for you
12 to 20 FPS is a milestone, not a target frame rate. Nothing here suggests you can play Saros on PC today. But the trajectory matters more than the number: in roughly four weeks the emulator went from booting the game at 1 FPS to holding it at 20 FPS with no major artifacts. Heldgames’ emulation survey still cautions that no PS5 emulator plays commercial games well yet, and that assessment remains correct for Saros. The difference is that the gap between “boots” and “playable” is closing faster than anyone expected.
Practical takeaways
- Check the KyTyPS5 compatibility list before trying any title yourself; builds change behavior between releases, so confirm against the latest build, not old videos.
- Do not upgrade your hardware for PS5 emulation right now. The October to November results prove that emulator updates move the needle more than GPU tiers do at this stage. If an upgrade is on the cards anyway, our budget gaming PC build guide covers what to buy in 2026.
- Expect UE5 exclusives like Saros to lag behind lighter games in compatibility; Demon’s Souls Remake is the closer target for playable frame rates. Meanwhile, our PC settings for maximum FPS guide helps you squeeze more frames out of the real PC games you already own.
- Use only game files you legally own. KyTyPS5 ships no copyrighted software, and that is by design.
The verdict
Watch this project, do not bet on it yet. KyTyPS5’s Saros run is the most exciting proof of progress in PS5 emulation this year: a UE5 exclusive went from a 1 FPS boot to 20 FPS with correct rendering in about a month, driven by software work rather than hardware upgrades. If the pace holds, the lighter games in the scene’s test library could cross into real playability before too long.
