Problems with debugLayer in Firefox

[Robbiewolf 0]

Hello all,

I am not sure if I am alone in this, but I seem to have some performance issues with the debugLayer in firefox.

If I open the basic scene(or any other scene for that matter) in the playground I have a solid 60 fps. But as soon as I show the debugLayer(either via the button on the top menu or via debugLayer.show) the fps drops to around 3. Removing the debugLayer puts the fps back to 60.

I see no errors in the console. I tried to replicate this issue in Chrome and Edge but it works fine there.

Is this a problem at the side of Babylon or Firefox?

Here is a link to the playground:

I am not seeing this behevior:

What version of firefox are you using?

[Robbiewolf 0]

Firefox 57.0.2 (64-bits)
Could it then be a problem with the pc itself?

I am using the same version. Anyone else experiences this problem?

I also see a small difference. (Firefox 57.0.2)
With debug layer = 53 fps
Without = 60 fps

I get the same numbers with IE 11. In Chrome and Edge i always have 60 fps.

No problem here as well

 

Can you try to do a profiler session to see where the CPU is used ?

Looking at the profile, it doesn't really tell me anything.(perhaps I am looking in the wrong place)

Something to note. Once I used the debugger it stays slow, it will show around 60 fps on the playground again. But my pc won't stop being slow until I close the tab that has the playground in it.

Here is the profile and a picture of it.

profile.json

 

My Task manager doesn't really tell me much either, since my CPU is only around 20%

Unfortunately this does not help me either

Debug Layer requires a lot of HTML operation and can slow things down for sure. But hardly to the value you are seeing

i think the log tools can help more than live debug layer
