To check whether a PC game supports your operating system and hardware, compare your PC’s actual specifications with the game’s current official system requirements. On Steam, find the game’s System Requirements section; then check the listed operating system, CPU, memory, graphics hardware, storage, and any specific feature requirements against your own PC. A match tells you whether you meet the stated baseline—not what frame rate or visual quality you will get.
What do I need before checking compatibility?
You need the current requirements for the exact game and version you plan to play, plus the actual specifications of the PC you will use. The game’s official store listing or publisher support page is the reference point; a computer’s product name or a general claim that it is a “gaming PC” is not enough to establish compatibility.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThis guide gives a Steam-focused way to find requirements and a Windows method for identifying the graphics device. The exact steps for checking processor, memory, and storage can vary by operating system, so use your operating system’s current documentation if you need help finding those details.
Before comparing anything, make sure you have the right listing. A game may have different platform versions, editions, or requirements that change over time. Check the page for the exact game you intend to install, and revisit it if you are checking again after a major update or if the publisher has posted newer support guidance. A third-party summary or an older screenshot can be useful context, but it should not replace the current official listing.

It also helps to keep two questions separate: whether the game lists support for your OS and hardware, and how well it may perform on them. The first is a comparison against the publisher’s stated requirements. The second depends on conditions that a requirements list does not fully specify, including the game’s updates and your intended resolution and settings.
How do I check a game’s operating-system and hardware requirements?
- Open the exact game’s current official listing. On Steam, open the game’s Store page and scroll to System Requirements. Steam says system requirements for games are listed on their Store pages. Record the supported operating system, minimum and recommended specifications, storage requirement, and any additional notes. Requirements are game-specific and can change as a game is updated. Steam Support explains where to find requirements.
- Check the operating system and architecture. Compare your installed OS with the listing, including any stated version or 64-bit requirement. “Windows” by itself does not establish that every Windows edition or architecture is supported. If you use macOS or Linux, check that game’s listing for explicit support for your OS rather than assuming that support for one PC operating system carries over to another. Steam provides guidance for checking whether a game is available on your platform.
- Compare the CPU and installed memory. Check the processor model and installed memory shown for your PC against the game’s published figures. Compare each item with the corresponding requirement; a stronger result in one category does not erase a shortfall in another.
- Identify the actual graphics device. On Windows, press Windows+R, type
dxdiag, and press Enter. Inspect the System and Display tabs. The Display tab identifies the graphics device and includes its driver version and release date. That device model—not the laptop or PC’s marketing name—is what to compare with the game’s graphics requirement. See Steam’s instructions for identifying graphics hardware and driver information. - Check any named graphics feature. If the game specifies a DirectX version, feature level, or pixel-shader requirement, compare that requirement with what the GPU hardware supports. The DirectX version installed in Windows does not by itself prove that the graphics device supports the required feature level or pixel-shader capability. Steam explains the difference between DirectX and graphics-hardware capabilities.
- Check free storage. Compare the game’s stated storage requirement with the space available on the drive where you intend to install it. Use the requirement shown for the game you plan to install; do not assume that a drive with enough total capacity also has enough free space.
- Read the notes and verify anything unclear. Requirements can include game-specific conditions. If a listing is unclear or seems inconsistent with the version you intend to play, check the publisher’s current support guidance rather than treating an unclear line as proof of compatibility.
Write the listed values down before you begin comparing. That simple step makes it less likely that you will overlook a note, confuse minimum with recommended, or compare your PC with requirements for a different platform. For each item, mark whether it appears to meet the minimum, the recommended level, both, or neither. If the listing gives a specific model or feature rather than a simple amount, record it exactly; do not replace it with a broad label such as “modern GPU.”
Outdated Drivers Are Slowing You Down

A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11Steam’s documented graphics-inspection method is specifically for Windows. If you use another operating system, or need processor, memory, and storage lookup steps, follow the current instructions for that operating system. The comparison itself remains the same: match the actual device or amount in your PC with the particular item the game lists, and ask the publisher about any ambiguous requirement.
How should I compare minimum and recommended requirements?
Minimum and recommended are separate thresholds stated by the game’s publisher. Compare your PC against both, component by component, and treat them as guidance—not as a universal promise about how the game will run. The available evidence does not establish a single definition that every publisher uses for these labels, so the specific game’s own wording matters.
A practical comparison looks like this:
| Check | What to compare | What a match establishes |
|---|---|---|
| Operating system | Your installed OS and architecture versus the supported OS and any stated version or 64-bit condition | Whether the listed OS condition appears to be met |
| CPU | Your processor model versus the listed processor | Whether your CPU meets that published threshold |
| Memory | Installed system memory versus the stated amount | Whether the listed memory threshold appears to be met |
| Graphics | Your actual GPU model and any required hardware features versus the game’s graphics requirement | Whether the listed graphics baseline appears to be met |
| Storage | Free space on the intended installation drive versus the stated capacity | Whether there is enough space for the stated requirement |
| Performance evidence | Game-specific information at your intended resolution and settings, if available | A better-informed expectation, not a guarantee |
Keep the minimum and recommended rows distinct while you do this. If the PC meets the minimum tier but not the recommended tier, you can say it meets the publisher’s stated minimum on the items that match. You cannot infer a precise frame rate or settings preset from that result. If it meets the recommended tier, that still does not guarantee a particular resolution, graphics preset, or frame rate.
Do not treat a comparison as a point system in which extra memory cancels out a GPU shortfall, or a faster CPU cancels out an unsupported operating system. Each listed item answers a different question. A mismatch in one category is worth investigating on its own; it does not automatically show that every other part of the PC is inadequate.

Steam Support puts the performance distinction plainly: “Simply meeting the system requirements does not mean you’ll have high FPS or strong in-game performance.” The full Steam performance guidance also notes that updates can affect performance on older hardware. Treat the listed requirements as a useful baseline for a compatibility check, not a measurement of how the game will behave under your preferred conditions.
Why isn’t the DirectX version enough to check GPU compatibility?
The DirectX version installed on a PC and the graphics hardware’s supported capabilities are different checks. Windows may report an installed DirectX version that does not establish that the GPU supports the feature level or pixel-shader capability a particular game requires.
Use the game’s specific requirement and the actual graphics-device information together. If the listing names a feature, do not treat an installed DirectX version alone as proof that the hardware can provide it. Steam’s DirectX and Pixel Shader guidance explains this limitation.
This distinction matters when a listing names a specific graphics capability rather than only a GPU model. Your PC may have a DirectX version installed, but the hardware still needs to support the capability the game calls for. Conversely, knowing the GPU’s name is not enough if the requirement also calls out a particular feature. Check both parts of the requirement instead of treating one number as a shortcut for the other.
If you cannot tell whether a device supports a named feature, do not guess from the graphics card’s marketing label or the DirectX version alone. Use the hardware vendor’s current specifications or the publisher’s support information for the exact game. The aim is to resolve the named requirement with information about the actual hardware, not to infer support from a general description of the PC.
What does a compatibility match tell me—and what doesn’t it tell me?
A match means your PC appears to meet the requirements the publisher chose to list for the game. It is a useful baseline check, not a performance guarantee. Requirements alone do not promise a target frame rate, high settings, or a particular resolution.

Actual results can also be affected by driver condition and game updates. If you are troubleshooting, record the graphics device and driver version first, then consult the relevant graphics-hardware vendor’s current driver guidance. Steam recommends checking and updating drivers as part of troubleshooting; its driver instructions help identify the information needed before looking for the correct driver.
Use the Display tab in dxdiag to note the graphics-device name, driver version, and release date before you look for a driver. These details help you identify what is installed and avoid searching by the PC’s brand name alone. Follow the appropriate vendor’s current instructions if you decide a driver update is needed; identifying a driver is not, by itself, evidence that a driver is out of date or that updating it will fix a compatibility shortfall.

A game update can also change how the game performs on older hardware. If a PC used to run a title differently, or a listing appears out of step with the version now offered, consult the publisher’s latest support guidance. A successful result in the past does not settle what the current version supports, and meeting the current listed baseline still does not settle the exact experience you will get.
For a more useful expectation than a requirements match alone, look for information specific to the game and the resolution and settings you intend to use. If that information is not available, be clear about the limit of the comparison: it can tell you whether the stated requirements appear to be met, but it cannot produce a reliable frame-rate prediction by itself.
What should I do if my PC falls short?
First, identify the exact shortfall. A PC that misses a stated graphics feature has a different problem from one that lacks storage space or does not meet a listed OS condition. Do not assume that a generic upgrade or optimization step will solve an unrelated limitation.
- Operating-system mismatch: Check whether the publisher lists support for your specific platform and OS condition. Do not assume that a general OS label means every edition or architecture is covered.
- GPU or graphics-feature mismatch: Confirm the actual graphics device and the feature it supports. Steam lists a graphics-card upgrade as one possible response when a PC does not meet requirements, but that does not mean every graphics shortfall has the same remedy.
- Memory shortfall: Confirm the installed amount against the listing. Steam identifies a memory upgrade as another possible response when requirements are not met, but whether it is appropriate depends on the specific shortfall.
- Storage shortfall: Check available space on the intended installation drive against the game’s stated requirement.
- Unclear or changed requirement: Consult the publisher’s current support information for the exact game and version. Requirements may change as a game is updated.
Steam’s performance troubleshooting guidance discusses requirements, drivers, and possible hardware responses. Use it as troubleshooting context, not as a recommendation to upgrade before you have identified what—if anything—your PC fails to meet.

There is no universal upgrade answer for every PC that falls short, and a requirement comparison alone does not establish what a particular change would cost or whether it is practical for your system. Start with the component or condition that misses the game’s listing. If the issue is an OS condition, a GPU purchase is not an answer to that mismatch; if the issue is storage, a graphics upgrade does not create more room on the installation drive. Investigate a component change only when the comparison points to that component, and confirm that the proposed change addresses the stated gap.
Likewise, a driver check is not a substitute for meeting a hardware requirement. Steam recommends checking drivers when troubleshooting, but a driver update cannot be assumed to add a hardware capability that the GPU lacks. If the hardware feature is the issue, verify the device’s capabilities and the publisher’s requirement before deciding what to do next.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How can I compare two PCs for the same game?
Use the same game listing as the reference for both PCs and compare the same categories in each: supported OS and architecture, CPU, memory, actual GPU and required feature support, and free storage. Keep the game’s minimum and recommended tiers separate so the comparison does not collapse into a vague “runs it” verdict.
For a useful side-by-side check, write down each computer’s exact OS condition, processor model, installed memory, graphics-device model and any relevant hardware feature, and free space on the intended installation drive. Then compare both sets of details with the same listed requirements. If a value is unknown, mark it as unknown rather than assuming the PC meets the requirement. For graphics, the Windows dxdiag Display tab can help identify the device and driver details on each machine.
If both PCs meet the listed baseline, the requirements do not tell you which will deliver a better experience at your chosen resolution or settings. Look for relevant game-specific performance information at those settings if it is available; otherwise, treat the requirements comparison as a compatibility check rather than a head-to-head performance result. A requirements page is not a benchmark of the two systems, so it cannot rank them for every use case.
If one PC meets more of the listed recommended items, that is a useful difference to note, but it is still not a guarantee of superior performance under all settings. Keep the conclusion tied to what you checked: which listed conditions each computer meets, which are uncertain, and where a game-specific performance expectation remains unknown.

Frequently Asked Questions
Can an online compatibility checker replace comparing the game’s requirements myself?
Treat a checker as a convenience, not the final authority. Its detected hardware and game information may not establish the current requirements for the exact version you plan to use. Verify the result against the game’s official listing or publisher support information, and identify the actual graphics device if the detected result is unclear.
What if the game’s store page lists an operating system but not my exact version?
Do not assume that a broad OS label covers every edition or architecture. Look for a stated version or architecture condition, and ask the publisher’s support channel if the listing leaves your specific setup ambiguous.
Why does my PC’s product name not tell me which graphics card it has?
A PC or laptop model name can describe a whole system rather than the graphics device inside it. The graphics-device model is the detail to match against the game’s requirement; on Windows, the Display tab in dxdiag can identify it.
If a game launches, does that prove my PC is fully compatible?
No. Launching does not establish that the PC meets every published requirement or will perform acceptably at your preferred settings. Check the relevant requirements and performance expectations separately.
If my PC meets the minimum requirements, can I expect a particular frame rate?
No. Minimum requirements are a publisher-stated threshold, not a frame-rate promise. Steam Support says that simply meeting system requirements does not mean you will have high FPS or strong in-game performance.
The Bottom Line
Check the current official requirements for the exact game, then compare its OS and architecture, CPU, memory, actual graphics device and required features, and storage with your PC one item at a time. On Windows, dxdiag can identify the graphics device and driver details. A match establishes only that you appear to meet the publisher’s listed baseline—not that the game will deliver a particular resolution, setting, or frame rate.
