Hi,

we recently updated from Gazbeo 5.1 to 7.3 and have problems with very low FPS in the gzclient (~2 FPS).

After some investigation I found that the FPS return to normal when I disable sending Visual messages on the '~/visual' topic. We use Visual messages to change light signals by making the bright visual visible/unvisible and to indicate the robot's localization from the robot software in the simulation. When sending messages for a localization indicator with 5 Hz the FPS drop from 40 to 18 and when additionally changing a single light signal with 2 Hz the FPS drop further to 1.7

Is this an issue I should report, especially because this was no problem in 5.1, or is there a new better way to change Visuals during the simulation?
