Hi,

cuda means that a NVidia GPU is required. I am not aware if SURF has been also implemented for other GPU (like a port on OpenCL instead of Cuda).

In term of performance, it depends on the scale of the environment, but binary features like BRIEF or ORB can work well for small/medium environments (assuming always same lighting conditions).

Also, are you using the UI on the RPI? If so, go in Preferences->3D Rendering and increase decimation option to reduce the number of points to show.

cheers,
Mathieu
