a thread to limit down the fps to 60 has already been in the C2 forum, but seems that no one had the solution.
As I saw you can do several things in the package.json, such as disable chrome devtools which can be good if you want to put your game on steam (while steam take screenshots with F10, and chrome usually open devtools with this key) I was wondering if it is possible to limit down the fps too ? or any other way to do it ?
