Minimum requirements
Refer to the Download page for the current minimum operating system and hardware requirements of Capture.

Real-time visualisation and rendering is very demanding on the video card. As a good referenced point for the capabilities of your hardware you may find PassMark Software's video card benchmark pages for high end GPU's useful. A PassMark G3D mark of 2000 or more could be considered a general minimum performance requirement for Capture, but in practice the actual requirements will vary a lot depending on how you use Capture.

If you are running Capture on macOS then your drivers are part of the operating system and we recommend that you always update macOS to the highest version officially supported by Capture.

If you are running Capture on Windows, always make sure that you have the latest drivers for your video card. We recommend downloading the latest drivers from the manufacturer of your video card, ie. NVidia, AMD or Intel. If you are running Capture on a laptop, be ware that it may have multiple video cards and we always recommend having the latest drivers for all of them.

eGPU support
Capture already runs and functions well on any eGPU supported by your operating system. Running Capture on an eGPU is no different from running on any other video card if you have multiple built-in or discrete video cards.

You may however need to configure your system so that it knows which video card Capture should run on though. On Windows this is done through the video card manufacturer's own configuration utilities. On macOS you set the "Prefer External GPU" option for the application in the window that appears when you issue the Get Info command for Capture (full details on https://support.apple.com/en-us/HT208544).

Low visualisation performance
If you are using Capture 2021, refer to the Performance Tuning section of our reference manual.

If you are using an older version of Capture, visit our dedicated page for visualisation performance to learn how to maximise visualisation performance in large projects.
