Poor performance on MAC

Hello thanks for the wonderful tool that Cesium is.
I have bewn working on Windows, Ubuntu, Android, Iphone and cesium works well on all these platform.
However on Mac performance is poor on safari and worst on chrome.
Any Suggestions?
Thanks in advance,


Glad you hear you like Cesium! Sorry to hear about your performance problems. We have Mac users on our development team and haven’t seen performance issues like that. It might be specific to your OS and graphics card. What version of MacOS is your computer running and what graphics card do you have? Also, do you have a sample application that you’re seeing the problem with, or is it just any Cesium app?

Make sure your graphics driver is up to date. Also check if there are updates for Safari and Chrome.



Hello Hannah,
Thanks for the quick response,
Please find bellow the link to demo application where you can see performance issues on Mac as compared to Windows PC:

Additionally the system config as bellow:
OS X EI Capitan (version 10.11.6)
2.5GHz Intel Core i5
16GB 1600 MHz DDR3
Intel HD Graphics 4000


Okay, thanks for the information. I’ll see if someone on the team with a mac also sees the performance problems


Poor performance on macbooks with integrated GPU and Safari. Chrome doing everything much better.
