Hello everyone ; so i spent the 3 last days trying to findout what causes the gzclient over using the cpu to 100% when running gazebo immediately, even though I have no models loaded and have the simulation paused. i ve got ubuntu 15.04 , rosjade , dual graphic card but i m only using the gtx765m .

your help is greatly appreciated regards from a real newbie

Short answer: it has to do with how rendering is doing and the fact of not limiting the refresh rate. I understand that in this situation (what happens in gazebo) what developers are asking to the machine is to generate images as fast as it can so the CPU is at 100%.

Long discussion:

I don't think that we currently have a way of doing it in gazebo.

7th Gen i7, Ubuntu 16.04, Gazebo 7, NVidia GT218. GZServer still causing high CPU usage. HOWEVER, same OS Gazebo work faster in my laptop with no graphics card and i5 processor. Somebody please find a solution.

I'm having the same exact issue. Using Ubuntu 14.04, Nvidia GTX660M with proprietary drivers. OpenGL shows direct rendering. Anybody have any thoughts?
