How It Works

1

Fleet of Hardware

We run a plugin on multiple Steam devices that connects to our orchestration backend, allowing us to test games simultaneously across our fleet.

2

AI Takes Control

An LLM is instructed to launch the game, skip menus and intros, and navigate the UI until it gains camera or character control.

3

Settings Discovery

The AI locates the graphics settings menu and begins systematically testing different configurations to find the most performant setup.

4

Comprehensive Testing

Multiple configurations are tested, including quick-access-menu settings like refresh rate and FPS limits, until the optimal settings are found.
