For some reason I can't understand, when opening a Cesium app in my Chrome Browser, the performance is awful. I'm talking about that point where it gets so stuck you can barely navigate.
· If I open the same apps in Internet Explorer, they work just fine.
· If I re-install Chrome, the apps work fine - for a while. After a few minutes (or refreshes, I can't tell) the laggynes comes back.
To me, it's quite obvious the problem is located at Chrome. But I can't seem to pinpoint what it is.
What operating system/device are you testing on? And what version of Chrome are you using? Have you also tried testing it out in Firefox? I’m curious if it’d have the same issue.
Most likely this is due to Chrome blacklisting an old video card driver and disabling hardware acceleration. You can check http://webglreport.com/ and see if it reports
Major Performance Caveat: Yes
If it does, that means you’re using software rendering which makes Cesium basically unusable.
I'm using 64 bit, so I guess than won't explain it. Actually, judging purely by looking at the performance tab in the windows task manager, one could think problem is CPU related. CPU stays over 90% constantly, where as RAM doesn't cross the 60-70% threshold (working on an i-7 with 8Gb of RAM).
Could you give me any hint on why would Chrome do this? Normally I would just google myself on how to force the hardware accelaration, but I'm facing the following issue: I'm developing a web app with Cesium for internal use in my company. And my corporate laptop is the one having the problem. That means that it might eventually happen in every single laptop of my colleagues. And forcing some setting in a few hundred laptops doesn't seem like a good idea...
So I would like the understand why is this happening so I can find some more generic solution that my sysadmin colleagues could deploy easily.
