I've just released hxScout 0.3.0 with the improved performance I've been hinting at. Go check it out at http://hxscout.com/haxe.html
FYI, you don't need to checkout my repos anymore. And OpenFL 3.1.1 and later supports telemetry with a simple
Dtelemetry option -
other frameworks set a couple vars, etc. All the details are on the page.
Let me know if you have questions or feedback.
