New lag issue .io game. Video example.

[Dextros]

This is a strange one.

I play a game called Defly.io and I'm trying to help the Developer sort an issue with the game.

Once the game servers experience some stress the game begins to lag.

This will ONLY happen in certain scenarios which have to be set up and easily replicated for this lagging issue to be applied.

The kicker and what I'm most confused about is that in the exact same scenario where the game is lagging, all you have to do is open up the DevTools and boom, everything is fixed and lag free.
What does the DevTools do to the webpage? Does it enable or disable anything? I am so confused.

I've linked a video below of what happens in game;

Any help with this would be massively appreciated.

 

Kind Regards,
