### Example <a href="#bkmrk-example-3a" id="bkmrk-example-3a"></a>

This command starts EXAPLAN with the following operations:

* Load the startup project: "startup.json"
* Forces the rendering load on the second GPU. In this case, the first GPU is a low-end monitor graphics card running the UI display, and the 2nd is the high-performance card.
