Yes—System Requirements Lab’s free “Can You RUN It” checker can quickly compare your Windows PC with a game’s listed requirements. Treat its result as a first-pass check, not a promise of smooth play: it compares detected specifications with a requirements database; it does not benchmark the game or predict exact frame rates. Before buying, verify any borderline result against the publisher’s requirements and, where possible, game-specific benchmarks or a demo.
How to check whether your PC can run a game
- Open the official Can You RUN It checker and search for the game.
- Select Can You RUN It? and follow the prompt to download its detection application if requested.
- Run the downloaded installer and detection program, then return to the browser results page. The official instructions describe installing
Detection.msi, choosing Run Detection, and returning to SystemRequirementsLab. - Review the minimum and recommended results, then inspect each component result—especially any failure or borderline GPU, VRAM, storage, or operating-system check.
- Confirm important details manually before spending money. The checker’s database contains more than 13,000 games, but its result still depends on the accuracy and currency of the listed requirements.
The service says it scans your CPU, GPU, RAM, operating system, and DirectX version, then compares those details with requirements in its game database. Its detector requires Windows for hardware analysis. Documentation about supported systems is not entirely consistent, so do not assume every operating-system version or Mac workflow is supported by the System Requirements Lab detector.
What the result tells you—and what it does not
A requirements checker is not a benchmark. A pass means the detected component appears to meet the corresponding entry in the database. A fail means a detected value appears below that comparison point. Neither result measures actual FPS or fully reproduces the game on your PC. The tool can be useful for screening, but it cannot guarantee a particular resolution, graphics preset, frame rate, or level of stability.

|---|---|
| Minimum | The publisher’s stated floor for supported play. It may mean lowering resolution or graphics settings; there is no universal minimum-performance target. |
| Recommended | A higher target that may support better settings or performance, depending on the game. Check whether the publisher states a resolution, preset, or frame rate. |
| Pass | The checker believes the detected part meets that database requirement—not that the game will run smoothly in every situation. |
| Fail | A listed component appears below the requirement. Verify the hardware and requirement before concluding the game cannot run. |
| Unknown or inconclusive | The detector or database could not make a dependable comparison. Use manual checks and the publisher’s own information. |
System Requirements Lab’s guidance characterizes a minimum pass as generally consistent with low-to-medium settings and a recommended pass as generally consistent with medium-to-high settings. Those are broad expectations, not a frame-rate guarantee. Publishers define requirements differently: one game’s “recommended” could target a different resolution or frame rate from another’s. Look for an explicit target in the game’s official requirements whenever one is provided.

Why a green result can still disappoint
A listed-specification comparison may not account for your exact game patch, driver quality, background applications, laptop power mode, heat or thermal throttling, or memory configuration. It may not capture slow storage, shader-compilation stutter, CPU bottlenecks in busy scenes, ray tracing, mods, texture packs, anti-cheat or launcher problems, poor optimization, or multiplayer network conditions. Your resolution and settings also change the workload.
So read a green result as “meets the listed requirement”, not “will run perfectly.” If you need to know expected performance at a particular resolution and preset, look for benchmarks that name the exact CPU and GPU, game version, settings, and test conditions—or try a demo where one is available.
Why a red result may not mean the game is impossible
A failure can identify a real limitation, but check for mistakes before writing off the game. The tool may have detected an integrated GPU instead of a laptop’s discrete graphics card, misread shared or dynamically allocated VRAM, or compared your PC with an outdated or incomplete database entry. A requirement may also be expressed in a way the checker cannot normalize accurately. And some games may still launch below their published minimum, although performance and stability are uncertain.

Check the exact model names shown by Windows, then compare them with the game’s official requirements. For a GPU or CPU near the line, independent benchmarks for that exact part and game are more informative than a brand name or product-family label alone.
Check your PC manually in Windows
You do not have to rely on an automated detector to identify your main specifications:
- Settings → System → About: check your processor and installed RAM.
- Task Manager → Performance: see CPU, memory, GPU, and disk information. On a laptop with multiple GPUs, check which GPU is listed and which one is active when a game runs.
- Settings → System → Display → Advanced display: check display and refresh-rate details.
- System Information: search Windows for
System Information, or press Win+R, entermsinfo32, and press Enter. - DirectX Diagnostic Tool: press Win+R, enter
dxdiag, and press Enter. The System tab shows the DirectX version; the display tabs provide graphics information. Microsoft also documents usingdxdiagin its Windows gaming guide.

- Compare the full CPU model, not just “Core i5” or “Ryzen 5.” Generations and specific models within a family differ substantially.
- Compare the full GPU model, including generation and laptop or mobile designation. A laptop GPU can perform differently from a similarly named desktop part.
- Confirm whether the game will use integrated or dedicated graphics. A laptop may contain both.
- Check the game’s stated VRAM requirement. System memory shared with integrated graphics is not a full substitute for dedicated graphics memory.
- Verify Windows edition/version and 64-bit support, installed RAM, and available storage—not just total drive capacity.
- Look for requirements that a simple component comparison can miss: an SSD, DirectX feature level, AVX or AVX2 processor instructions, a particular Windows version, ray tracing hardware, launcher, anti-cheat, or internet connection.
- Compare the publisher’s stated target with your intended resolution and settings. A PC that can start a game at reduced settings may not meet your preferred experience.
If the checker fails or gives an unexpected result
- Verify the detected part. Compare the checker’s CPU and GPU names with Task Manager or System Information. On a laptop, make sure the discrete GPU is not being overlooked.
- Check the official requirement. Game requirements can change or be reported differently across databases and storefronts; use the publisher’s current listing as the baseline.
- Confirm drivers and graphics selection. Update the graphics driver from the GPU maker or PC manufacturer, and set the game to use the high-performance GPU if your laptop has one.
- Check practical limits. Confirm free storage, RAM, VRAM, DirectX support, and any SSD or CPU-instruction requirement.
- Look for relevant benchmarks or a demo. Match the tested GPU and CPU as closely as possible, and pay attention to resolution and settings.
- Decide before making an expensive upgrade. Identify the failing component and your target resolution and frame rate first. A checker result alone is not enough to justify replacing a PC or buying a graphics card.
If the detection app will not run, confirm that you downloaded it from the official domain, check Windows Security for a block or quarantine notice, and try a fresh download rather than an old installer. Do not blindly bypass a security warning. If the detector remains blocked or you would rather not install it, use the manual checks above.
If a game passes but stutters or performs badly, investigate drivers, patches, shader compilation, thermals, memory configuration, background processes, storage, and CPU/GPU utilization while playing. For a performance test, try lowering ray tracing first, then resolution or render scale; reduce texture quality if VRAM is constrained, followed by shadows, volumetric effects, or crowd density. Upscaling may help if the game supports it. These are troubleshooting options, not guaranteed fixes.

Game compatibility is not Windows 11 eligibility
Microsoft’s Windows 11 minimum requirements cover installation eligibility, not gaming performance. They include a compatible 64-bit processor running at 1 GHz or faster with at least two cores, 4 GB RAM, 64 GB storage, UEFI firmware with Secure Boot capability, TPM 2.0, and DirectX 12-compatible graphics with a WDDM 2.0 driver, among other requirements. A PC can meet those minimums and still be unsuitable for a demanding game.
For Windows 11 eligibility, use Microsoft’s official PC Health Check guidance; it answers a different question from a game checker and does not assess game performance. Microsoft states that Windows 10 support ended on October 14, 2025. That support-status date does not change what hardware a particular game needs.

Is Can You RUN It safe to use?
System Requirements Lab says its detector collects hardware and system-software information—including CPU, Windows version, RAM, graphics card, sound card, and DirectX—and says it does not collect personally identifiable information. That is the service’s own description, not a reason to treat any download as risk-free. Download only from the official System Requirements Lab domain, check the installer’s publisher details, avoid third-party mirrors, and review rather than ignore Windows Security warnings. If you no longer want the detector, uninstall it after use.

The service’s documentation has inconsistencies: one FAQ lists supported operating systems only through Windows 10, while the current checker says Windows is required and separate Can I Run It documentation describes Windows and Mac applications. These are not enough to assume the System Requirements Lab detector supports every current OS. If the detector is unavailable on your system, manual checks remain an option. Avoid relying on unverified claims about permissions or device access; check the current installer and privacy information for yourself.
