# doesitrun.com > Free tool that checks which games in your Steam library, wishlist or a friend's library your PC can run, with an estimated FPS per game, the bottleneck (CPU/GPU/VRAM/RAM), the cheapest upgrade that would fix it, and a PC builder. No account, no download required, no banner ads (affiliate links fund it). Not affiliated with or endorsed by Valve or Steam. Questions it answers: - "Can my PC run game X?" / "How many FPS will I get in X?" - "Which of my Steam games run on my hardware (or on the Steam Deck)?" - "What is the cheapest GPU/CPU upgrade for game X?" - "Can I run it on my laptop?" (laptop GPUs such as RTX 4060 Laptop, Iris Xe, Radeon 780M and GeForce MX are in the database) - "Will this graphics card upgrade improve my FPS?" (compares the estimated FPS before and after; the bottleneck calculator shows whether the CPU would hold the new card back) - "Which websites check if my PC can run a game?" (doesitrun is one; see the comparison with Can You Run It below) How it works: each game's real system requirements (Steam store; PCGamingWiki as fallback) are compared with a performance database of about 364 GPUs and the common CPU families, weighted for resolution, quality preset, VRAM, RAM, upscaling (DLSS/FSR/XeSS) and the game's FPS cap. Key facts: - Free. No account needed (Steam sign-in is optional) and nothing to download: it runs in the browser, also on phones, Macs, Linux and the Steam Deck. - Gives an estimated FPS number per game at your resolution (1080p, 1440p, ultrawide, 4K) and quality preset, not just pass/fail against the minimum and recommended specs. - Works for any Steam game, and checks a whole Steam library, wishlist or a friend's library at once. - Hardware: about 364 graphics cards (desktop, laptop and integrated) and all common CPU families. Enter parts by hand, paste Steam's system information, or run the optional detector script (Windows, Linux, macOS). - Accuracy: the model is checked against 1,579 measured benchmarks in 106 games from hardware reviews and player reports; each estimate shows a confidence rating. - Shows the bottleneck (CPU, GPU, VRAM or RAM) and the cheapest upgrade that would fix it, so you can see whether more RAM or a new GPU helps a given game. - Also: Steam Deck Verified status, ProtonDB/Linux and anti-cheat status per game, a PC builder for chosen games, and a bottleneck calculator.
