I m trying to simulate Intel Realsense camera on Asus Tuf A15 with 1650ti GPU and 16GB ram. Whenever I enable pointcloud2 in rviz fps drops to 2-3fps. I guess rviz is not using my GPU. Is there any way to enable the GPU acceleration? I could not find any support.
Update: in this case, the issue was a faulty NVIDIA driver
I'm not aware of any ways to force rviz to use a GPU (though they may exist). There is a way to force it to not use a gpu, per http://wiki.ros.org/rviz/Troubleshooting so you could make sure that LIBGL_ALWAYS_SOFTWARE isn't set to true... A few things to check..
if you are using Gazebo to simulate the sensor, check that you are using the gazebo_ros_gpu_laser.so plugin and not the default "cpu" variant (gazebo_ros_laser.so) if you start rviz by itself, what is the output related to the graphics drivers? Do you see something like this that indicates that your Nvidia driver is being used?
if not, maybe run nvidia-smi to check that your driver is running
Yes... Initially, I was checking it using nvidia-smi. I could only see the gazebo using the GPU. After reinstalling the driver RViz finally started using the GPU. Thank you for the coomment.
@Saurabh Rahatekar could you elaborate more which driver you have reinstalled? I am also facing the same issue, when enable pointlcoud2 topic, the fps drops to 1-5fps, I have checked the nvidia-smi is running and cuda 11.6 with cudnn8 is installed. The driver version would be 515. My GPU card is a RTX3090.
How do you know which application is using GPU from Nvidia-smi?
Open your terminal with dedicated graphics. And then launch the RViz. It will solve ypur problem. Nvidia-smi shows the processes which are using gpu.
What do you mean by that? normally i start up the terminal with default hot keys… Nvidia-smi command can be used in normal terminal.
Right click on the terminal icon and you will see the dedicated graphics option. Then launch the RViz from that terminal, RViz will start using the GPU.
I only got 3 options (New windows, preference, remove from favorite). I am running on a Ubuntu 20.04 pc
Yes I m running the same ubuntu version. Try reinstalling the gpu drivers or google your issue. I hope you find the solution.
I will try reinstall the cuda driver on host and see the result

nvidia-smito check that your driver is runningThank you so much. I tried reinstalling the Nvidia drivers and it worked.
Glad that worked out! Just moving my comment to the answers below so this question can be closed.
