When I display hd or qhd point cloud on RVIZ, the fps drops to around 1 and eventually 0. My laptop (Intel i7, NVIDIA GeForce GT 640M) also slows down drastically. My CPU usage gets really high however I would have thought that my NVIDIA graphics card would be utilised when displaying point cloud?

How do I know whether my GPU is being utilised for RVIZ? Is my laptop not capable for this?

Thanks
