Can I use a second GPU as a capture card? is a common question among content creators and streamers. This practice involves repurposing an extra graphics card to capture video content from external sources like gaming consoles. While it can be cost-effective and potentially offload tasks from the primary GPU, it has limitations in terms of compatibility and capture quality. Configuring a second GPU for this purpose requires specific setup and software adjustments to optimize your content creation and streaming experience.

Why Consider Using a Secondary GPU for Capture?

Before delving into the specifics of using a second GPU for capture, let’s explore the reasons why someone might consider this option.

Cost-Effective Solution

One of the most prominent advantages is cost savings. If you already have a spare GPU, putting it to use as a capture card can be a budget-friendly alternative to purchasing a dedicated capture card. However, it’s important to ask, Are PNY graphics cards good? to determine if your secondary GPU is up to the task.

Improved Performance

Dedicated capture cards can sometimes impose a slight performance overhead on your primary gaming rig. Using a secondary GPU can potentially offload the capture tasks, resulting in a smoother gaming experience.


A secondary GPU can be versatile. When it’s not functioning as a capture card, you can still utilize it for other tasks, such as rendering, video editing, or mining, depending on its capabilities.

Learning Experience

For enthusiasts and those who enjoy tinkering with hardware and software, repurposing a GPU can be an educational journey in understanding how video capture and GPU processing work.

Challenges of Using a Secondary GPU for Capture

While the idea of using a secondary GPU for capture has its appeal, it comes with several challenges and limitations that you should be aware of.

Driver and Software Compatibility

Not all graphics cards or drivers are compatible with capture software. Some may lack the necessary features or drivers to support video capture functionality.

Capture Quality

The capture quality depends on the capabilities of the secondary GPU. While it may be sufficient for basic capture, it may not match the performance of dedicated capture cards with advanced features.

Dedicated Hardware

Capture cards are designed with specialized hardware for video capture, encoding, and processing. A secondary GPU doesn’t have these dedicated components, which may limit its capabilities.

Resource Consumption

Using a secondary GPU for capture may consume additional system resources, potentially affecting your gaming or other tasks running on the primary GPU.

Setting Up a Secondary GPU as a Capture Card

If you’re committed to using a secondary GPU for capture, here’s a step-by-step guide to help you get started.

Step 1: Check GPU Compatibility

Ensure that your secondary GPU is compatible with the capture software you intend to use. Popular software like OBS (Open Broadcaster Software) and XSplit provide compatibility lists on their websites.

Step 2: Install GPU Drivers

Install the necessary drivers for your secondary GPU. Ensure that the drivers are up-to-date to provide optimal performance and compatibility.

Step 3: Configure Capture Software

Set up your chosen capture software (OBS, XSplit, or others) to recognize and utilize the secondary GPU. Configure the capture settings to match your desired recording or streaming quality.

Step 4: Connect Video Sources

Connect the video sources you want to capture to the secondary GPU. This could be your gaming console, another PC, or any device with video output.

Step 5: Test and Adjust

Test your setup to ensure that the secondary GPU is functioning as intended. Pay attention to performance and capture quality. You may need to adjust settings to achieve the desired results.

Step 6: Monitor Resources

Keep an eye on system resource usage. Using a secondary GPU for capture may increase CPU and RAM usage. Make sure your system can handle the additional load.

Alternative Options

If the challenges of using a secondary GPU for capture seem daunting, or if your spare GPU isn’t up to the task, there are alternative options to consider:

Dedicated Capture Cards

Invest in a dedicated capture card. These devices are purpose-built for video capture and offer advanced features, often surpassing what a secondary GPU can provide.

External Capture Devices

External capture devices, also known as external capture cards, offer portability and flexibility. They can capture video from various sources and connect to your computer via USB or other interfaces.

Nvidia NVENC and AMD VCE
