When I launch gazebo from the command line, both gzserver and gzclient consume 100% cpu and FPS hovers around 2-2.5. Interacting with the GUI is too laggy to be usable even with an empty world. If I scale the display resolution to the lowest possible, I see performance increase to 3.5-4 FPS, but things are still unusably slow.
The homebrew formula is from the osrf/simulation tap. I believe this installation is following best practices. Any insight into why I'm seeing such poor performance would be appreciated. Thanks!
