I have an issue with a simple gradient background I made for a game.
When I run the game without it, I stick around 40fps. As soon as the background is added it drop to 20fps.
I tried a tilebackground 16x720, a sprite 32x32 that I resize to fit the layout (960X720) , I even tried the full image 960x720 (which I know will hit performance) but whatever I do the fps drop 50%.
I have the same fps behavior on my Acer Iconia tablet and Galaxy S3 phone. I am using CocoonJS for export.
Any help or tips would be greatly appreciate
