doesitrun

doesitrun is a free web tool that checks which games your PC can run. Sign in with Steam, paste a SteamID or profile link, or enter your hardware by hand, then see your whole Steam library, your wishlist or a friend's library sorted by how well each game runs.

For every game it estimates the FPS, shows the limiting part of your system (CPU, GPU, VRAM or RAM) and names the cheapest upgrade that would fix it. A built-in PC builder puts together a full parts list for a target game and resolution, and a budget view helps you find games that fit a price range.

It also has a page for every popular game ("Can I run it?") with the official system requirements and estimated FPS per graphics card, graphics-card pages with a tier-list ranking, GPU-vs-GPU comparisons, a best-GPU-per-game page and a bottleneck calculator. Steam Deck and other handhelds (ROG Ally, Legion Go) are covered, including Linux/Proton compatibility and anti-cheat status, and the estimates account for upscaling (DLSS/FSR/XeSS) and each game's FPS cap. An optional small detector can read your CPU, GPU, RAM and VRAM automatically.

Available in English, German, Spanish, French and Portuguese. No account, no ads, and nothing needs to be installed to use it. Estimated FPS is a guide calculated from each game's requirements and calibrated against real benchmarks and player reports, not a direct benchmark. Not affiliated with or endorsed by Valve or Steam.
