You run sphinx in a VM and your real time factor is 5%, that’s way too low. If your machine meets the requirements and is properly configured (with latest GPU drivers): System requirements - 2.7 , you might want to take a look at this page to speed up the simulation: How to speed the simulation up - 2.7
I recommend using sphinx outside the virtual machine, and you have to be sure that your GPU is properly recognized and configured. I don’t see any reason why you can have such a low real time factor with an empty world if your PC meets the requirements and is properly configured.
Your GPU does not seem to be properly installed. If you are still inside a VM I don’t know what you should do. Otherwise, you have to install nvidia drivers.
