I've been reading on ways to improve performance on my game and read that having too many objects using physics (Bullet behaviour in my case) can cause slow downs/frame drops.
I've got an endless runner game and i've got 7 seperate objects that use Bullet behaviour (4 or 5 of them are for backgrounds and the rest are for gameplay such as platform, obstacle & powerups). The bullet behaviour i'm using is from the auto runner template with just some tweaks to the bullet speed.
So i was wondering if there is an alternate method, other than Bullet behaviour, that i can use for some of my objects (mainly the background ones) so that it still has infinitie scrolling (as i've got right now) and in turn hopefully improve performance?
