What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
To check whether a game will run on your PC, compare the game’s current minimum and recommended system requirements with your computer’s operating system, processor, memory, graphics hardware, storage, and any stated graphics features. In Windows, the built-in DirectX Diagnostic Tool (DxDiag) shows several of those details. The comparison is a useful screening check—not a promise of a particular frame rate, resolution, or smooth performance.
1. Find the game’s current system requirements
Check the current store listing or publisher support page for the exact game and edition you plan to use. On Steam, requirements are listed on the game’s Store page. Record the minimum and recommended specifications separately; also note the supported operating system, storage requirement, and any named DirectX version or graphics feature.
Requirements can differ between games and editions, so don’t substitute an undated third-party listing when the current store or publisher information is available. If a requirement is unclear, look for clarification from the publisher or the hardware maker rather than guessing from a similar model name.
2. Find your PC’s specifications in Windows
DxDiag is built into Windows and can help you identify the processor, installed memory, graphics adapter, driver details, and DirectX version.

- Open the Start menu and search for dxdiag, or press Windows key + R, type dxdiag, and press Enter.
- If Windows asks whether to check for digitally signed drivers, choose Yes to continue.
- On the System tab, note the Windows version, processor, memory, and DirectX version.
- Open the Display tab and note the graphics device name and driver version and date. A laptop with more than one display adapter may show multiple Display tabs.
DxDiag helps identify what is installed; it does not by itself determine whether the hardware meets a particular game’s requirements. In particular, the DirectX version shown on the System tab does not prove that the graphics adapter supports every DirectX feature or shader capability a game may require.
3. Compare the matching requirements
Compare the same categories, using the game’s minimum list to check its stated baseline and the recommended list to check its higher specification. Use the full model names where possible: processor and graphics generations matter, and comparing only clock speed or manufacturer is not enough.

| Check | Compare | Why it matters |
|---|---|---|
| Operating system | Your Windows version and edition against the game’s stated support | An unsupported OS can prevent installation or launch. |
| Processor (CPU) | Your full processor model against the listed minimum or recommended CPU | Names and generations matter; clock speed alone is not a reliable comparison. |
| Memory (RAM) | Installed system memory against the stated capacity | Capacity is one requirement, but it does not alone predict performance. |
| Graphics hardware (GPU) | The exact graphics adapter model against the listed GPU | Integrated and dedicated graphics differ; compare the actual adapter, not just its brand. |
| Graphics API and features | Any required DirectX version, feature level, or shader capability | The installed DirectX runtime and the GPU’s supported features are separate checks. |
| Storage | Available space against the game’s stated storage need | Allow for the installation and check the title’s own requirement. |
| Driver and software state | Whether a compatible graphics driver is installed and current | Outdated drivers can cause problems even when the hardware appears sufficient. |
For a laptop or a PC with both integrated and dedicated graphics, confirm which adapter the game is using if it runs poorly. Many notebooks use integrated graphics, which may be less capable than dedicated graphics; the result depends on the specific chip and game.
4. Interpret the comparison without overpromising
If your PC meets the listed minimum, that means it meets the publisher’s stated baseline—not that the game will deliver a particular FPS or run smoothly at your preferred resolution and settings. Steam Support puts it plainly: “Simply meeting the system requirements does not mean you’ll have high FPS or strong in-game performance.” Requirements are not a universal performance benchmark, and outcomes vary by game and PC.

A system near the requirement line can still have launch or performance problems. Meeting the hardware entries also does not resolve a separate operating-system, graphics-feature, storage, or driver shortfall.

If one or more requirements are below the game’s list
- Identify the exact shortfall—such as the OS, CPU, graphics adapter, memory, storage, or a required feature—before deciding what to do.
- Check the PC or component maker’s information if you are unsure whether two processor or graphics models are comparable.
- Do not assume a graphics-card purchase is the answer. Laptops and prebuilt systems may have limited upgrade options, and compatibility depends on the exact computer, power supply, chassis, and component.
A graphics-card or memory upgrade may help in some cases, but the shortfall and the PC’s compatibility need to be established first. There is no universal upgrade that guarantees a specific game will run.

If the PC appears to meet requirements but performance is poor
- Check for a compatible graphics-driver update from NVIDIA, AMD, Intel, or the computer manufacturer, as appropriate for your system.
- On a hybrid-graphics laptop, verify that the game is using the intended graphics adapter.
- Consult the game publisher’s support guidance for the specific launch or performance symptom.
An older driver can affect performance even if the graphics hardware meets or exceeds the listed requirement. These checks help narrow down the cause; they do not guarantee a fix.
