Utilizing OpenCL makes it possible to accelerate your processing significantly. When Auto is selected Capture One will test the capability of the graphics card, and if the card proves to be powerful enough Capture One will use it for processing.

To enable the processing you need to switch to Auto in the preferences as shown below. In Capture One version 7.1.2 and 7.1.3 the default setup is not to use OpenCL for processing. For Capture One, only relatively new GPU cards have enough computing power and onboard RAM to be utilized effectively. OpenCL essentially enables effective utilization of thousands of compute units within modern graphics cards. OpenCL is short for Open Compute Language. OpenCL is an open standard defining how to interface and utilize all the processing capabilities within graphics cards (GPU) and multiprocessor CPUs. When using one of the newest graphics cards on the market in a Mac Pro computer, you can process a full 80 megapixel raw file in less than 2 seconds. The speed advantage of using OpenCL can be huge. In Capture One 7 the graphics card is used for accelerated processing not just to the display, but also when processing images to files. The idea is to make it possible to fully utilize the processing capabilities of the graphics hardware to get a faster application. You can take advantage of this speedup option by using graphics card accelerated processing through an interface called OpenCL.
