Some games can still use two graphics cards, but CrossFire no longer works as a blanket setting that applies to every title. Whether a second GPU does anything depends on the graphics API the game uses and on whether the game itself supports multi-GPU rendering. AMD’s guidance, last updated June 19, 2025, draws that line clearly: DirectX 9, 10, and 11 games need an AMD CrossFire driver profile, while DirectX 12 and Vulkan games must support multi-GPU operation within the application.
The short answer
Multi-GPU gaming is still technically possible, but support is title-specific. AMD’s configuration guidance says multi-GPU support and performance vary by application and graphics API. It does not publish a current list of games that work with CrossFire, and neither does Microsoft’s Direct3D documentation. The only dependable way to know whether your game uses a second card is to check that game’s own documentation or settings.
How the graphics API decides what happens
The API a game is built on is the first thing to check, because AMD assigns responsibility differently for each one.
| Graphics API | Who provides multi-GPU support | Where you enable it | What to verify |
|---|---|---|---|
| DirectX 9, DirectX 10, DirectX 11 | An AMD CrossFire driver profile, which AMD identifies as the requirement | AMD driver configuration (AMD Software: Adrenalin Edition) | That a CrossFire profile exists for the specific title. AMD’s guidance does not list which games have one. |
| DirectX 12 | The application (the game) must support multi-GPU itself | The game launcher or the graphics/video settings menu, where the developer offers the option | An explicit multi-GPU option in the game, or developer documentation describing it |
| Vulkan | The application (the game) must support multi-GPU itself | The game launcher or the graphics/video settings menu, where the developer offers the option | An explicit multi-GPU option in the game, or developer documentation describing it |
AMD’s CrossFire configuration guidance states the DirectX 12 and Vulkan rule directly: “With DirectX® 12 and Vulkan® 3D Applications, multi-GPU support is exclusively handled by the application and should be available as an option in the game launcher or within the graphics/video settings menu.”

Why a DirectX 12 or Vulkan label is not proof of multi-GPU support
A common assumption is that a modern API automatically lets a game use every installed GPU. AMD’s guidance says otherwise. For DirectX 12 and Vulkan, the game has to implement multi-GPU support, so the API name alone tells you nothing about whether a second card will be used.
Microsoft’s Direct3D 12 documentation on multi-adapter systems describes two situations: applications that explicitly target more than one adapter, and driver-managed multi-adapter scenarios. That is a capability developers can build on. It does not mean a retail game splits its rendering across two cards, and it does not promise any performance gain from a second GPU.

What CrossFire means today
AMD describes CrossFire as a multi-GPU technology that combines graphics cards to render 3D graphics. Its support material still explains how to configure it. That documentation shows the technology is still supported in the sense that AMD documents it. It does not show that any particular current game will use it, so treat the existence of a configuration guide as separate from game compatibility.

AMD’s MGPU configuration article, updated June 19, 2025 and based on Adrenalin Edition 25.6.1, makes the same point: results depend on the application and the graphics API. If you are reading this in late 2026, check AMD’s support pages for any newer revision, since the most recent guidance available for this article predates it.

Can I use two graphics cards for gaming?
Yes, in the games that support it. The practical answer depends on which of the two paths the game uses:
- Older API, driver-based path: DirectX 9, 10, and 11 titles rely on an AMD CrossFire profile. If the profile is missing, a second card will not be used for that game.
- Newer API, application-based path: DirectX 12 and Vulkan titles rely on the developer’s implementation. If the game offers no multi-GPU option, the second card will not be used.
How to check a specific game before you buy a second card
- Identify the exact game and its graphics API. Use the developer’s PC documentation for the title. Do not infer the API from the release year or the engine name.
- Look for a multi-GPU option in the game. For DirectX 12 and Vulkan titles, open the game launcher or the graphics/video settings menu and search for a multi-GPU or CrossFire option. If none exists and the developer documents no multi-GPU support, treat the game as single-GPU.
- For DirectX 9, 10, or 11 titles, check for an AMD CrossFire profile. Open AMD Software: Adrenalin Edition and follow AMD’s configuration guidance for CrossFire. Confirm that the profile applies to your exact game, because AMD’s guidance does not publish a list of titles.
- Verify the hardware combination independently. Neither AMD’s guidance nor Microsoft’s documentation verifies any specific pairing of cards. Confirm the GPU models, the motherboard slots and their lane configuration, the power supply capacity, the driver version, and the game version before you buy.
- Test before relying on it. Run the game with the second card enabled and compare frame rates and stability against the single-card baseline.
Setting realistic performance expectations
Do not expect a second card to double frame rates. AMD’s guidance says performance varies by application and by graphics API, so any scaling you see is specific to that game and that configuration. The same caution applies to memory: a second card does not automatically make the game see a combined pool of video memory.

Because support is inconsistent, a second card is a poor purchase if you are buying it only for one title that may not support it. A single-card upgrade is often the more predictable path for a game that lacks multi-GPU support, and the sources used here do not establish that a second card is worth buying for any particular game.
