I have been using FlashDevelop to work with Stage3D for over a month now without problems. I have been compiling with the debug the entire time while maintaining a 60 fps, until yesterday I was toying around with matrices and my project started to lag. Slowly running at around 5 fps then climbing its way up to about 30 – 50 fps. Normally I would assume it was a fault of my own, however my project runs fine in the release player and I tried compiling other projects with the debugger resulting in the same issue. Is there any particular reason that my debug compiler suddenly is running slow?
