How It Works
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.
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.
Settings Discovery
The AI locates the graphics settings menu and begins systematically testing different configurations to find the most performant setup.
Comprehensive Testing
Multiple configurations are tested, including quick-access-menu settings like refresh rate and FPS limits, until the optimal settings are found.
