Choose Game Capture or Display Capture in OBS

The short answer

On Windows, use Game Capture when you want to show a single game and nothing else. Use Display Capture when you need to show everything on a monitor, such as switching between apps, browsing or presenting. The main condition is that Game Capture only works with applications it can hook into, and Display Capture can show a black screen on some laptops with two graphics processors. If one source fails, the other is usually the fallback.

For speech, the more important point is that neither source captures your microphone. Your voice, including a webcam's built-in microphone, comes from a separate audio input in OBS. The choice of video source mostly affects which computer sounds are mixed in alongside your voice.

What each source captures

Game Capture attaches to a running game or other graphics application on Windows that draws with DirectX, OpenGL or Vulkan. It records only that application's output, so desktop notifications, other windows and the taskbar stay out of the shot. It also works with games running in exclusive fullscreen, which Display Capture often cannot record reliably.

Display Capture records an entire monitor exactly as it appears. Everything on that screen is included, such as pop-ups, private messages and other windows. That makes it flexible but riskier for privacy during a live stream or call.

Game Capture is a Windows feature. On macOS and Linux, OBS offers screen and window capture sources that use the operating system's own capture methods instead. On those platforms the choice described here does not apply in the same form.

Comparing the two for your priorities

Criterion | Game Capture | Display Capture

What appears on screen | One game or graphics application only | The whole monitor, including notifications and other windows

Privacy during streams or calls | Lower risk of showing unrelated content | Higher risk of showing messages or pop-ups

Exclusive fullscreen games | Generally supported | Often black or unreliable

Non-game apps (browser, slides, desktop) | May not capture them | Captures them

Common failure modes | Some anti-cheat systems block the hook; some apps cannot be hooked | Black screen on some hybrid-graphics laptops if OBS runs on a different graphics processor than the display

Application audio option | Recent Windows versions of OBS may offer a per-source audio capture option | No source-level audio; computer sound comes from the global Desktop Audio device

Platform | Windows only | Available on all platforms in some form

Performance is often cited as a reason to prefer Game Capture, because it reads frames directly from the game instead of copying the whole desktop. No measurements comparing the two under the same hardware, game and settings were available for this guide, so no ranking or figures are given here. If performance matters to you, compare both sources on your own system with the same scene and settings, and watch the OBS stats panel for skipped or lagged frames.

How the choice affects captured speech

OBS treats video sources and microphones separately. Your voice reaches OBS through the Mic/Auxiliary Audio device set in the audio settings, or through an Audio Input Capture source added to a scene. A webcam's built-in microphone shows up there as an ordinary input device, often named after the camera. If you add the webcam's picture with a Video Capture Device source on Windows, that source may also offer settings to bring in the camera's audio. Use one route for the microphone, not both, or your voice can be doubled or slightly out of sync.

Where the two capture types differ is in computer audio. With Display Capture, game or app sound comes from the global Desktop Audio device, which carries everything the computer plays. That includes notification sounds and the voices of other people on a voice chat or video call. With Game Capture, if your OBS version provides an audio capture option on the source, you can record just the game's sound and turn Desktop Audio down or off. This keeps other people's voices and system sounds out of the recording, which makes your own speech easier to follow.

• If you want only your voice and the game: use Game Capture with its audio option enabled where available, and mute or remove Desktop Audio.
• If you need to show several apps: use Display Capture, and expect Desktop Audio to carry every sound the computer plays unless you route specific apps elsewhere.
• In either case: check the OBS audio mixer while you speak to confirm that only your microphone meter moves when you talk.

When routing through OBS Virtual Camera

If you send your OBS scene into a conferencing app through OBS Virtual Camera, keep in mind that the virtual camera carries video only. The conferencing app still picks up your voice from whatever microphone is selected in its own audio settings, such as the webcam's microphone or a headset. Choosing Game Capture or Display Capture does not change what the meeting hears from you.

If you want meeting participants to hear game or app audio as well, you need a separate audio routing method, such as a virtual audio device. That setup is outside the scope of this guide. Whichever method you use, avoid sending the call's own audio back into the call, because it can cause echo. Wearing headphones also stops a webcam microphone from picking up sound from your speakers.

Gaps in the available evidence

No specifications, benchmark results or version-specific release details were supplied for this guide. The comparison above relies on how each source is documented to work, not on measured tests. Menu names and options, especially the audio option on Game Capture, can differ between OBS versions, so check the properties of the source in your installed version before you rely on it.
