Changing size in Project.xml causes program to lag in Flash
My game is lagging when I change the resolution in Project.xml to 800x800. It was previously 640x480. The fps drops to 45, when it is usually 60. This only happens on Flash, HTML5 works fine. I've never had anything like this happen before. My operating system is macOS Sierra 10.12.6 . I have a link to the code repository below, can anyone tell me what might be causing this? Thanks.
I think performance in flash is pretty bad in general. I tried some of the flixel demos in flash on macOS and the performance for those isn't great either if you up the resolution. Is your goal to make a flash game? It is probably better to move to html5 for web games.
