Box2d problem with perfomance

cocos2d-x C++
#1

My cocos2d-x app using box2d and physics is slowly. If I use world->setSpeed(2) then app lags sometimes. What to do with this low perfomance? How to increase speed of my game?

#2

Did you setup cameras? I used Box2D directly and before setting them, objects appeared to move slowly but that actually was unit scale issue and cameras.

#3

Cameras? Never hear about them before. Could you link me?

#4

Here is what I used as reference How to use new Camera system? . Modifying default camera Camera::getDefaultCamera() through lookAt() or setScale() might be enough, depending on what you need.
