Ashley Thanks for the info - That all makes sense. if you are rotating layers/layout does that make a difference?
Silverforce - I suppose you are right. I have a lot of wants wrapped up in how I chose to layer my game. Thanks.
Arima - I am running multiple force to own texture layers. (do different blend modes affect a layer the same way as a webgl effect in terms of cpu usage?
This is my current layer list, it is running fine so far. I think my computer was performing poorly when I was doing some stress tests. I am running the following on an i5 with 25-40% cpu usage. This includes calculating physics as well:
layout effects + post processing including scaling and rotating
light effects (screen, dodge, or other effects used)
BackGround (destination over)
Liquid (using various shaders)
Light effects and illumination (multiply/forces own texture)
Explosions, fire, lasers, and other nonsense (additive blend mode)
