Mobile performance. Tests

All tests carried out on iPhone4 /w ios5. And actRact (mobile version I'm doing). It would help to play the game to understand better:

scirra.com/arcade/addicting-rotary-games/659/actract-lite

All tests carried after playing for 60seconds at level 4(all shapes spawns). The lightning effect is always activated (to increase object count). Tested on local preview.

Sprites Rotation:

Planet fixed.

Objects on screen min: 10 -> fps: 25/26

Objects on screen max: 15 -> fps: 22/23

Planet rotates.

Objects on screen min: 10 -> fps: 24/26

Objects on screen max: 15 -> fps: 21/23

Planet rotates. Shapes rotates.

Objects on screen min: 10 -> fps: 23/24

Objects on screen max: 15 -> fps: 21/23

Result. Rotating sprites affects fps slightly.

Particles

No Rotations:

Objects on screen min: 10 -> fps: 15

Objects on screen max: 15 -> fps: 12

Rotations:

Objects on screen min: 10 -> fps: 13

Objects on screen max: 15 -> fps: 11

Particles have a huge impact.

Many objects

No Rotations:

Objects on screen min: 10 -> fps: 22/24

Objects on screen max: 50 -> fps: 13/14

Rotations:

Objects on screen min: 10 -> fps: 22/25

Objects on screen max: 50 -> fps: 11/13

Many objects equals less fps (duh).

I hope this is of help for someone, I encourage you to post your test. And how appmobi affects this.

Great that you did this! Was these test using phonegap?

I wanted to try it on my iPad2 and return with numbers but I can't pass the first screen (due to touch support, I guess).
