How could I check if there is something else in the render loop?
The dev tools are amazing for this in chrome it is where I did the graph and you can also see what is slow and what is not 
hum but it’s running well on chrome…
It might help you pin point the slow path else the dev tools in FF are pretty decent too so probably could be a great help as well.
Thank you, that’s very kind, how can I identify the “slow path”? What is a slow path? Sorry i’m quite beginner
