Graphics card is a GeForce RTX 4090 with 24GB. Render settings give me a choice of Nvidia GeForce, OptiXNividia GeForce, and the CPU. Which one should I pick?

The 4090 works great in the Optix setting. Just for fun I recommend setting up a scene (using Superfly) and rendering it all three ways: CPU, GeForce, and Optix. Compare the times. It's dramatic. But afterwards you'll stick with Optix for sure.
