This tutorial will explain a little bit about how certain features in the C2 runtime work. And how they can impact your performance. It might or might not be th...
Most of these issues has been fixed or significantly improved in C3, with the C3 runtime, but if you're having any performance issues you can test if any of these issues might be the problem. Some doesn't really apply any more like putting sprites together in the same object as c3 builds it's own spritesheet regardless of what object they belong to.
Some of the issues might still applied, but I haven't done any large enough project lately that needed that level of optimization.
I have no doubt that's the case, as I've tried to keep up on Ashley's posts when new runtime stuff is mentioned.......little of it that I understand. LOL
The difficulty is isolating the issue because I have been working on individual objects and then threw them ALL into the mix at once. So there's already so much to try to isolate. I don't know that I'd know where to begin.
