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.
Real Benchmarks
Actual FPS data from real gameplay, not estimates
Always Updated
Automatically retested when games receive updates
Free & Open
No ads, no paywalls, just optimized settings
Stay Current
Get notified when games receive new tests

Game Request & Voting

Help Us Prioritize

Want to see a specific game tested? You can vote for games to help us prioritize our testing queue. Here's how it works:

  • Each user can vote for 1 game per day
  • Games with more votes are more likely to be tested sooner
  • Gifting a game to us earns it 20 votes immediately

Note: Voting helps prioritize games, but doesn't guarantee immediate testing. We manually review the most requested games and select based on various factors including testing complexity, game popularity, and community interest.

Frequently Asked Questions

Who's behind this?

Hardware enthusiast
Hey there! I'm a solo developer who loves gaming on Steam hardware, and honestly, I got tired of spending more time tweaking settings than actually playing games. So I built DeckTuner to solve that problem for myself and the community.

Running AI agents to test games 24/7 isn't cheap (those LLM costs add up fast!), so if you find this useful and want to help keep the lights on, I'd really appreciate your support. But either way, I hope this helps you spend more time gaming and less time in settings menus.
