How to enable GPU for rviz
ZhangZh3ng opened this issue · 3 comments
I need to render a large number of point cloud and marker array in rviz, now the rviz fps is very low(< 1fps), I tried to open a terminal with GPU(mine is Nvidia1050Ti) and then run rviz in that terminal, but it doesn't help. I found the the GPU memory usage by rviz is very low(4 Mb) which is abnormal. So I want to know is there any way to enable GPU for rviz?
Your environment
- OS Version: Ubuntu 20.04
- ROS Distro: [Noetic]
- RViz
$ rviz

The output OpenGL device: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 already indicates that the GPU is used for rendering.
Maybe you GPU is already overloaded with (pre)processing of the point-cloud data, i.e. receiving and preparing data for display? This is done in a separate thread for each PC display.

Thank you for your reply, maybe I need to decrease to point number.
Yes.
