# Shadow of the Colossus (PS4, CUSA08809) on PC
Unofficial. Not affiliated with, endorsed by or connected to Sony Interactive Entertainment,
Bluepoint Games or the shadPS4 project.
This project starts one game, Shadow of the Colossus (2018, CUSA08809), from a single program
on Windows, with keyboard, mouse and controller support, PC graphics settings, an uncapped
frame rate, a free play mode and an achievements panel.
It has two parts:
- **This repository**: the scripts and settings around the program (build, install, settings
 pages, key pictures, test and measurement scripts).
- **The runtime**, a game-specific build of shadPS4,
 a PlayStation 4 emulator. It lives in this repository too, on the branch
 `runtime`, and is checked out into the
 `runtime` folder as a submodule.
It is not a recompilation or a decompilation. The game's own PlayStation 4 program runs
unchanged on the runtime, which translates its system and graphics calls to Windows and Vulkan.
**No game file is here and none may be added.** You need your own copy of the game.
## How it runs
Ryzen 7 5700X3D, Radeon RX 9060 XT, 1080p, frame rate uncapped. Average / 1% low FPS:
| Preset | Gaius arena | Field with Agro | Valus arena |
|---|---|---|---|
| Low | 77 / 40 | 114 / 63 | 89 / 45 |
| Medium | 61 / 34 | 80 / 39 | 73 / 42 |
| High | 59 / 22 | 106 / 55 | 74 / 28 |
| Ultra | 59 / 35 | 102 / 56 | 81 / 38 |
### Battles and scenes
High preset, 1080p, no frame limit, with the performance readout. Frames of the benchmark videos recorded 2026-10-11 (build 61ad3f5); the averages are over each 24 s recording.
 Pelagia, 12th colossus: average 74 FPS 
 Phaedra, 4th colossus: average 93 FPS 
 Gaius, 3rd colossus: average 57 FPS 
 Malus, 16th colossus: average 63 FPS 
 Basaran, 9th colossus, firing: average 78 FPS 
 Dirge's desert: average 125 FPS 
 Phalanx's desert: average 76 FPS 
 Shrine of Worship: average 54 FPS 
Method, the third scene and the requirements: showcase/BENCHMARK.md.
Only this one PC has been measured; nothing has been run on Intel or NVIDIA graphics.
## How this works
The game is not rewritten. Its PlayStation 4 program file runs as it is, on a runtime that
stands in for the console:
- **The runtime is a custom build of shadPS4**, the
 open source PlayStation 4 emulator, licensed GPL-2.0-or-later like shadPS4 itself. It was
 branched from shadPS4 `main` at commit `945dbc3` (6 October 2026) and carries about a hundred
 commits on top, all on the branch
 `runtime`. The emulator's general
 parts (loading the program, the system libraries, the translation of PS4 shaders and
 graphics commands to Vulkan) are shadPS4's work.
- **What this build changes** is aimed at this one game: fixes for the faults that stopped it
 from starting and rendering; work on frame rate and frame pacing (saved pipelines, parallel
 loading, fewer stalls); keyboard and mouse input mapped to the game's button schemes with
 matching key pictures; mouse use of the game's menus; lines added to the game's own
