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
I think the Ruiz is not using the GPU in default. I also encounter this issue (low fps) in my desktop (i5-10400, RTX3090, 32GB ram). This desktop is clean built with ROS2 on ubuntu 20.04.5. When I just run Rviz2 it can achieve 31 fps, but when loading point cloud.. only 1-2 fps.
Fun fact is that I have also tried to build on a laptop and a desktop (same GPU, but i4-4790). Both machine works just fun and achieved a 20-30 fps when loading with the same pcd point cloud.
Totally out of mind how to fix this.
