How do I tiled background and optimisation ???

in order to optimize at maximum my game (optimisation about cpu usage , fsp and memory) i decide to rebuild my game from begining and optimize every thing even if it is small

trying to understand use of tiled background i have question ...

for example to use the paused black screen ( black screen with opacity of 50 ... just and exemple)

what is better for cpu usage and memory

in a layout of 500x500

1-use simple sprite object with black tile (for exemple 50x50) and resize it to 500x500

2- use tiled background (with pasted black tile 50x50) and resize it to 500x500

3-use tiled background (with pasted tile 5x5) and resize it to 500x500

thanks in advance

You probably won't see any difference in that.

i'm developping in mobile ...

Same.

But if you have to choose between 50x50 and 5x5 than better choose between 8x8 and 64x64.

Edit:

Question. On what kind of mobile are you testing this?

iphone 4 ... because its the cheapest ... and every one can buy it ... specially young person

Better aim for iphone 4s and newer, i tried to do my best to optimize my games for 4, but even the easiest games are working with 25-30 fps. And iphone 4 will not get the ios 8 update, because this device is no longer supported by apple, so that's why im not recommend you to aim for 4.
