You don't understand what I am saying, or I don't understand your question..
You were asking if it would be wise to make your image smaller and my answer was that it wouldn't matter that much, because it only take 615x194x4 bytes in memory..
Collisions have nothing to do with the image, amount of objects have nothing to do with the image..
So I don't know where these suddenly come from..
Cpu is something different from gpu..
I was talking about image memory usage..
Must be my question being confusing. I was asking about which is better for performance, resizing the Image of the TiledBackground smaller or resizing the Tiledbackground smaller itself? The other questions were just addons...
