Game Tools FAQ
Are these game tools really free?
Yes — every tool on this page is 100% free with no signup, no ads in the tool area, and no data collection. All calculations run locally in your browser.
Do these tools work on mobile?
Yes. Every tool is mobile-responsive. Calculations run client-side so they work offline once loaded.
Will using these tools get me banned?
No. None of our tools interact with game memory, inject code, or modify game files in ways that violate Terms of Service. They only analyze your hardware specs and connection metrics that you input manually.
How accurate are the FPS projections?
Our projections are heuristic estimates based on GPU tier databases and resolution scaling factors. Real-world results vary 10-20% based on drivers, cooling, and game optimization. Use them as a starting point, not gospel.
Can I use these tools for any game?
Most tools work for any PC game. Some (like the sensitivity converter) have game-specific presets for major shooters. The file integrity checker supports Steam, Epic, Battle.net, Xbox, EA, GOG, and Riot.
Why do my settings keep reverting after I change them?
Cloud sync is the usual culprit — disable cloud saves in your game platform, edit the config file, then re-enable. The Config Reset Tool has step-by-step instructions for each major game.
