Well I do got a lot of things with Bullet behavior at the start. Building a shoot em up without using the System Scroll Screen and Parallax Layers. So pretty much everything is flying passed the screen and being destroyed at -x positions. Wonder if its just better to go with parallax effect?
So I have noticed that if a sprite loads in a layout then its image is already loaded in the next layout if it exist there. I have title and continue screen so i was able to notice that the drop in fps was only happening on the first start up for the gameplay layout.
