Describe the issue

I am experiencing lag issues with the Open3D Visualizer on Ubuntu 20.04 when working with larger point clouds. However, the Visualizer performs well on the same PC running Windows 11. I would like to know what could be causing this issue.

Problem solved. Use the driver released by NVIDIA itself instead of the default Nouveau driver.
