    When running the demos from OpenGL Essentials I see that the CPU is 50% busy (a full core) and the GPU is 20% busy. I think that this is a heavy load on the computer since the graphics is very simple and the geometry is static most of the time.

    What can be done to reduce the load on the CPU/GPU such that I can start using the CPU for other (real) things?

    Optimizing the game loop is my first suggestion. The existing game loop is as simple as it gets — it runs as fast as it can and this will consume more resources than necessary.

    Here’s a good read on the topic of Game Loops, from the book/e-book Game Programming Patterns by Robert Nystrom.
