Just an aside, but the Roon UI has a lot in common with video games, and uses the OpenGL library, which in turn will use your GPU. See this post, and in particular:
The user interface is driven by a piece of technology that could be best described as a game engine. It supports fluid animations, and we are trying to keep the frame rate at 60 frames per second (fps), just like a game. It renders graphics using OpenGL and hardware acceleration, just like a game, too.
