Astro Bot runs as a native Windows port with DLSS Multi Frame Generation in AstroHybrid

Team Asobi's Astro Bot, the 2024 PlayStation 5 platformer that went on to win Game of the Year at The Game Awards, now has an unofficial native Windows port. The project is called AstroHybrid and its creator, who goes by imnotsharingmyname on GitHub, opened the source code and documentation on GitHub this week together with a setup app that builds the PC version on the player's own machine. Version 1.0.7 landed on November 13 after a rapid string of fixes in its first days.

The author is open about having built it with the help of AI coding assistants, and invites other developers to send pull requests.

Not an emulator

AstroHybrid stands on two existing open-source projects. AnyPS5 relinks the game's own x86-64 code into a Windows .exe and replaces the console's system libraries (input, audio, save data and so on) with native Windows versions. The graphics side comes from KytyPS5: its GPU code is built as a separate library that converts the PS5's rendering work into Vulkan.

On top of that, the port finds the game's own temporal upscaling pass while it runs and feeds its colour, depth and motion data to NVIDIA's DLSS. That unlocks DLSS Super Resolution, Frame Generation at 2x, 3x or 4x, an adaptive mode that picks the multiplier to hit a target frame rate, and Reflex for lower latency. Controller support covers the DualSense with rumble, light bar, adaptive triggers and motion, plus DualShock 4, Xbox, Switch Pro and generic pads.

How it performs

The game is still limited by the CPU. On the author's Ryzen 5 5500 with an RTX 5060, the game itself runs at about 32 to 34 FPS in the heaviest area tested and 37 to 53 FPS elsewhere; 4x Multi Frame Generation pushes that to around 125 FPS on screen. The author stresses that generated frames don't make the game respond like a real 120 FPS and that input latency hasn't been measured yet. DLSS needs an RTX card, frame generation an RTX 40 or 50 series.

Some things are still missing: the motion-controlled sections don't react to pads without gyro sensors, and the first loading screen can stay black for about half a minute with no frame limit. The project is described as a work-in-progress personal experiment, not affiliated with Sony or Team Asobi.

What you need

No game files come with it. You need your own decrypted dump of Astro Bot from a PS5 you own; version 01.019.000 is the one tested, and since 1.0.7 other regional releases are accepted too. The setup app only reads the dump and builds the Windows version from it in a couple of minutes, on Windows 10 or 11 with a Vulkan graphics card.

To try it with your own copy of the game, start from the AstroHybrid page on GitHub and read its instructions first.
