If your speed immediately improves, you had too many programs running for your RAM to deal with - keep this in mind in the future. We suggest that you start by looking through all your open desktop apps and closing down a few of them. A number of different issues can cause your Surface Pro to slow to a crawl.
Problem: My Surface Pro 4 is really, really slow Solution: Hopefully, the answer to your problem is below. That’s why we’ve collected the most common complaints about Microsoft’s latest professional tablet and provided you with helpful steps to make your Pro 4 well again in short order. Scroll down to find the problems, or use the toolbar at the bottom of your browser to quickly jump through any potential problems you might have. Nothing frustrates like getting a shiny new Surface Pro 4 and finding out it doesn’t work. "Proper" markup on Surface Pro as infrared, thus, hides sensor from the mentioned APIs and, respectively, OpenCV. Since OpenCV is supposedly interfacing directly to traditional Windows APIs, DirectShow and Media Foundation, it is highly unlikely that it is capable of capturing infrared stream out of the box, unless, of course, the driver itself represents it as normal video. UWP/OpenCV bridging might be on help there: Create a helper Windows Runtime component for OpenCV interop. Given that this is UWP API, you might have troubles fitting this all together with OpenCV if you need the latter. This API is built on top of Media Foundation and Sensor APIs and gets you infrared cameras even though underlying Media Foundation alone has no equivalent public interface. You can read infrared frames through a newer API offered for UWP development: Process media frames with MediaFrameReader, the keyword there is this: MediaFrameSourceKind.Infrared. Microsoft did not update the API to extend it to such inputs even though it is technically possible when it comes to undocumented. To my best knowledge Media Foundation API has no support for infrared cameras.
