Can I Run This Game?
How to use Can I Run It
- Visit System Requirements Lab in your browser. The page loads a search bar where you type the game’s name.
- Select the game from the dropdown results and click “Can You Run It.” The tool will prompt you to install a small detection plugin — this is a one-time step per browser.
- Once installed, the plugin scans your CPU, GPU, RAM, storage, and OS version. Within seconds, you get a color-coded result: green (pass), yellow (borderline), or red (fail) for each component.
The scan is entirely local — no uploads to a server — and the tool is free to use. For Windows and macOS users, it’s the fastest way to get an answer without manually comparing specs.
Understanding system requirements
Game publishers publish minimum and recommended specs, but those numbers aren’t always intuitive. Minimum means the game will launch and be playable at the lowest settings, often at 720p or 768p resolution. Recommended means it should run smoothly at 1080p with most visual features enabled. For example, Riot Games Support (official publisher specs) lists League of Legends minimum Windows RAM at 2 GB and recommended at 4 GB — a gap that makes a real difference in team fights with multiple champions.
The implication: beating the minimum is not the same as having a good experience. If you’re at or below minimum on any component, expect compromises.
A gamer on a budget faces a real choice: upgrade one component at a time to hit recommended specs, or optimize in-game settings for playable framerates. The data shows ~35% of PCs fail at least one requirement — the majority on GPU.
The takeaway: check your GPU first.
Can I Run It on a Laptop?
Laptop vs desktop performance differences
Laptop GPUs are not the same as their desktop counterparts. An RTX 4060 laptop GPU performs roughly 20–30% slower than the desktop version because of thermal constraints and lower power limits. The tool’s detection plugin reports the exact model number — but it doesn’t adjust its pass/fail judgment for laptop throttling. A green “pass” on a laptop means the hardware is technically capable, but sustained performance may dip below playable levels in demanding scenes.
- Thermal throttling: laptops heat up faster; after 20–30 minutes of gaming, the CPU or GPU may reduce clock speeds to cool down.
- Shared memory: many budget laptops allocate system RAM as VRAM. The tool detects this but can’t simulate the impact on frame rates.
- Driver updates: Nvidia and AMD release mobile-specific drivers. An outdated driver can cause the tool to report “fail” even when hardware is capable.
Steam Community discussions frequently report that owners of gaming laptops with RTX 3060 or better pass most modern game checks, but users should check laptop-specific benchmarks before buying demanding titles like Cyberpunk 2077 or Alan Wake 2.
Checking laptop-specific requirements
Use the same Can I Run It tool, but double-check the reported GPU against notebookcheck.net or similar comparison sites for real-world gaming benchmarks. The tool can’t predict the effect of a laptop’s power adapter — if the laptop runs on battery, performance drops significantly.
What this means: a pass on your laptop can still mean a choppy experience at higher settings. Always assume laptop results are optimistic by 15–25%.
Can I Run It on Mac?
Mac compatibility with Windows games
Most PC games launch only on Windows. If you’re on a Mac, Can I Run It will only check games that have a native macOS version. For Windows-only titles, the tool can’t help — but there are workarounds. Riot Games Support confirms League of Legends works on macOS 10.15 minimum and macOS 11 recommended, with the requirement for a GPU supporting Metal.
- Boot Camp (Intel Macs only): install Windows on a separate partition. Once booted into Windows, Can I Run It works exactly as on a PC.
- CrossOver / Parallels: translation layers that run Windows games on Apple Silicon Macs. Performance is usually 60–80% of native Windows — expect borderline specs to fail.
- Steam on Mac: filters library to show only macOS-compatible games. Use Can I Run It inside the browser on your Mac to check those titles.
Using Boot Camp or CrossOver
Boot Camp is the most reliable method for Intel Macs: it gives you full native Windows performance. On Apple Silicon, CrossOver 24 is the best option, but expect some compatibility gaps. Steam Support advises checking OS compatibility alongside hardware requirements — this becomes critical on Mac, where the OS version can determine whether a game even launches.
The catch: Mac users face a double hurdle — first, the Windows-only nature of most games, and second, the performance overhead of any compatibility layer. If your Mac barely meets a game’s recommended specs via Boot Camp, it will likely fail under CrossOver.
For Mac gamers, the “Can I Run It” question is really two questions: “Does this game have a Mac version?” and “Will my Mac meet its requirements?” The second question is answerable with the tool — the first requires checking the publisher’s store page or Steam’s “Mac” filter.
Can I Run It on Mobile?
Mobile version of Can I Run It
System Requirements Lab publishes a mobile app for Android and iOS that works the same way: search for a game, and the app checks your device’s specs against the game’s requirements. The app is aimed at mobile games — think Genshin Impact, Call of Duty Mobile, or PUBG Mobile — not PC titles.
- Detection: the app reads your phone’s chipset (Snapdragon, A-series, etc.), RAM, and display resolution.
- Results: pass/fail for each component, plus a note on supported graphics API.
- Not all PC games are available on mobile — the app’s database only includes mobile releases.
Limitations of mobile hardware
Mobile hardware is power-constrained in ways PCs aren’t. A phone that passes the check at default settings may still suffer from thermal throttling after 15 minutes of heavy gaming. The tool flags potential issues but can’t simulate real-world play. For example, a Snapdragon 8 Gen 2 phone passes most mobile game checks, but frame rates can drop by 30% when the phone heats up.
The pattern: mobile compatibility checking is less mature than on PC. Use it as a starting point, but check YouTube benchmarks for your specific phone model and the game you want.
Why Is Can I Run It Not Working?
Common errors and fixes
- Plugin not detected: The tool requires a browser plugin (or desktop app). If the plugin fails to install, try a different browser — Chrome and Edge work best. Firefox often requires manual permission settings.
- JavaScript disabled: The tool is built entirely on client-side JavaScript. If you have it disabled, the page won’t load the scanner. Enable JavaScript in your browser settings.
- Ad blocker interference: AdBlock, uBlock Origin, or similar extensions can block the plugin download. Disable them temporarily for the site.
- Outdated browser or OS: Older versions of Windows (pre-7) or macOS (pre-10.12) may not support the detection plugin. Update your OS or use the desktop app instead.
Browser compatibility issues
The tool’s plugin works via ActiveX on Internet Explorer (legacy) and as a browser extension for modern Chromium-based browsers. Safari and Firefox have limited support — the desktop app is more reliable on those browsers. If you’re still stuck, use the manual alternative: compare your specs against the game’s published requirements by hand.
What to watch: the most common error we see in forums is users on Windows 11 with strong hardware who get false failures. This is usually caused by Windows Defender blocking the plugin — add an exception for systemrequirementslab.com in your security software.

Quotes from the Community
One-click solution that looks at your computer’s hardware and system software to determine whether or not your current system can run a product.— System Requirements Lab (official tool description)
One of my friends is starting to get into PC gaming, and he didn’t know about checking specs before buying. This tool saved him from wasting money on a game his laptop couldn’t handle.— Reddit user (r/Doesthisexist)
On macOS, the game requires a GPU supporting Metal versions. If your Mac is older than 2019, check the Metal compatibility list first.— Riot Games Support
The trade-off with community advice: it’s grounded in real experience but may not apply to your specific hardware combination. Use it as a second opinion, not a final verdict.
What to Do If Your PC Can’t Run a Game
So you’ve checked, and your machine fails. What now? The decision tree is straightforward but requires honesty about your budget and priorities:
- Upgrade one component: GPU is the most common bottleneck. A mid-range GPU upgrade (e.g., from GTX 1650 to RTX 3060) can unlock dozens of new games. For more on game performance, see our article on Dragon Ball Sparking Zero: Hype, Repetition & Player Drop.
- Lower settings: Dropping resolution from 1080p to 900p or reducing texture quality can make a game playable on borderline hardware.
- Use cloud gaming: Services like GeForce Now, Xbox Cloud Gaming, or Amazon Luna bypass your hardware entirely — you stream the game from remote servers.
- Refund the game: Steam and Epic Games offer refunds within 14 days (less than 2 hours played). Use this as a safety net for risky purchases.
For laptop users, the upgrade path is limited — most gaming laptops allow only RAM and storage upgrades. For desktops, replacement parts are more accessible. Steam Support (official store guidance) reminds players that refunds are available if a game doesn’t run on your system.

Frequently Asked Questions
Is Can I Run It free?
Yes, the web tool and all its features are completely free. There’s no paid tier, premium subscription, or hidden charge. System Requirements Lab monetizes through optional ads, not user payments.
Does Can I Run It work on Windows 11?
Yes, Windows 11 is fully supported. The detection plugin installs as a browser extension or desktop app and works with all current versions of Chrome, Edge, and Firefox on Windows 11.
Can I use Can I Run It without installing anything?
No — the tool requires either a browser plugin or a desktop app to scan your hardware. There is no manual-entry version that works without installation. For a no-install alternative, compare your specs against the game’s published requirements by hand.
How accurate is Can I Run It?
Accuracy is high for standard desktop and laptop hardware, but there are edge cases: VR headsets, custom water-cooled builds, and very old drivers can produce false fails. The tool’s pass/fail rating is based on whether components meet the publisher’s minimum specs — it cannot predict real-world frame rates or settings.
What if Can I Run It says my PC can’t run a game?
Check the details — sometimes only one component fails (e.g., a missing GPU requirement). You can sometimes make the game playable by lowering settings, updating drivers, or upgrading that single part. If the fail is across all components, the hardware is genuinely inadequate; consider cloud gaming or a refund.
Can I run a game on a laptop that doesn’t meet the requirements?
Sometimes, at low settings and resolutions, but expect poor performance. Laptops that fail the minimum requirements are unlikely to provide a playable experience, especially for newer titles. Thermal throttling may also cause frame drops after 15–20 minutes of play.
Does Can I Run It check VRAM?
Yes, the tool detects VRAM (dedicated video memory) and compares it against the game’s requirement. VRAM is often a fail point for modern games at higher texture settings. The reported amount comes directly from your GPU driver.
How often is the game database updated?
System Requirements Lab updates its game database regularly as new titles launch. For very recent releases (less than 2 weeks old), the game may not appear in search results yet. In that case, compare specs manually using the publisher’s official requirements.
For gamers in the US or other markets where GPU prices are volatile, the choice is clear: use Can I Run It as your first check, then double-check with Game Debate or manual specs before buying. For laptop and Mac users, add a third step — search for your exact model’s real-world benchmarks on YouTube. One bad purchase avoided can pay for a mid-range GPU upgrade.
