How to Play InFamous Second Son on PC at 4K 60 FPS Using ShadPS4

InFamous Second Son, a PlayStation 4 exclusive that never officially launched on computer systems, can now run on PC at 60 frames per second and 4K resolution using a modified version of the ShadPS4 emulator, according to a report published on October 7, 2026. Running the game previously proved nearly impossible due to frequent crashes and graphical bugs, distinguishing it from other former console exclusives like Bloodborne that had already achieved high-resolution PC play. This gives new life to the game developed by Sucker Punch without major technical complications, provided players possess a powerful computer and a personal copy of the title.

Ayoub Uses AI to Optimize shadPS4 Rendering

A creator known as Ayoub released version 1.0 of the project, titled shadPS4-AYOUB1080p, on GitHub as a free download that requires only user-side configuration files, according to the community tracking these emulation projects. To bypass weeks of manual debugging, the developer used the artificial intelligence tool Claude to analyze extensive codebases and locate rendering bottlenecks within hours. The resulting build distributes graphical workloads across multiple processor threads and handles background visual effects to prevent the sudden crashes that previously halted gameplay, while also correcting errors such as the green screen that appeared when activating the PlayStation 4 Pro mode. The software is released completely free with no mandatory subscription or payment required, and the author clarified that any contributions on his Patreon page are strictly voluntary donations to thank him for his time.

Users Must Provide Legal Game Files for Installation

Players must supply their own legal copy of InFamous Second Son ripped directly from a PlayStation 4 console, as the GitHub project does not bundle copyrighted game files. The custom patches target the European version, designated as CUSA00004, and users can make the game start with a different copy though it will lack the improvements. The installation process requires downloading the main file for Windows from the version 1.0 page, extracting the content into a normal computer folder, opening the included user-files folder and copying everything inside without taking the entire folder, pressing the Windows and R keys, typing %APPDATA%shadPS4 to open the hidden data directory, and pasting the copied items there to automatically activate the PlayStation 4 Pro mode at 3200×1800 along with the remaining game adjustments. While the software is free, testing revealed that stable 60 frames per second depend heavily on high-end hardware, with the developer relying on an AMD Ryzen 9 9950X3D processor during optimization. Users playing at 4K must activate the 3840×2160 patch and deactivate the 3200×1800 one, ensuring only a single resolution patch is turned on at a time.
