I am optimizing my 2D mobile game. There are many sprites with POT size all over the game and I have filled their Packing Tag to enable batching and also checked their Generate Mip Maps checkbox. All these sprites have uniform scales in the game and most of them are (1,1,1).
What I intend to do is to minimize the number of Batches in the game.
What I want to figure out is how mipmaps affect the number of batches in a 2D game?
This is what I have tried:
I copied two sprites several times with different but uniform scales and reported the number of batches.
The circle has POT size and mipmap enabled; The square is not, it's just a sprite; Both have the same packing tag, so they reside in different atlases.
Also checking or unchecking Static for these game objects does not change anything.
3 batches when two different sprites are drawn
7 batches when two different sprites are drawn but in a little bit different positions
1 batch when only one mipmap sprite is drawn
1 batch when only one non-mipmap sprite is drawn. the positions of the game objects are the same as 1st test case where there were 7 batches.
