BackendFreak Thanks for your reply
I already read the Ashley's series, but I will read again to be sure. However my problem isn't about understand WebRTC (I already have some experience using that with webapps) , but just how to test it. It is not easy to emulate bandwidth and maybe someone knows an efficient method to do that.
About browser instances, they become inactive on focusout even if i don't minimize. E.g: I'm using 2 monitors where the Host and the Peer stay in separated browsers (Chrome and Firefox). The game still runing and nothing is lost, but I can't see the rendering. When the focus back to one of then, everything is updated to the correct place.
The real problem here is that I can't see if my animations are correct rendering between Host/Peer.
For now, I need to compile the project and test with 2 computers or virtual machines .
