OpenFrequently asked questions
Are these tools really free?
Yes — every tool on this page is free with no account, no trial and no download. We do not gate results behind a sign-up.
Do I need to install anything to check my PC?
No. Everything runs in the browser. You pick your GPU, CPU and memory from a list, and the calculation happens on the page.
How accurate are the FPS estimates?
Estimates are modelled from aggregated benchmark data for each GPU and CPU at a given resolution and preset. Treat them as a close guide rather than a guarantee — drivers, background load, thermals and specific game patches all move the real number.
Which tool should I start with?
If you have a specific game in mind, start with Can I Run It?. If you are planning an upgrade instead, start with the Bottleneck Calculator and then the Upgrade Advisor.
