I'm sorry for my english, but i will try to be clear)
I'm making a prototype of... something like a endless runner with top-down view. And i'm aiming to mobile devices. But i had face the problem: even with pretty good fps, like 35-50 gameplay is not feels smooth enough.
The core of game logic:
I have two background big sprites (1280, 720) with bullet behavior. I create them one after another outside of layout and they are flying on bullet behavior to the game window, making the effect of moving. Also I randomly spawn few objects with bullet behavior, which shoud create some variety of backgrounds.
On 60 fps it's working perfectly. But on 30-40 fps it's feels like the background and objects do not moving smooth. I would say it's look like it is moving jerkily.
Is there is a way to make it work more smoothly with 30-40 fps? I don't think i will able to get 60fps on every device.
