Hei, I have trouble in b2json.h on line 109, 110, 111.

bool readIntoWorldFromValue(b2World *existingWorld, Json::Value &worldValue) { return readFromValue(worldValue, existingWorld); }

I tried to compile cocos2d-x 3.4 project in VS2013 IDE.
I get warning message: performance warning.
Can I know what that means?

What does the error say exactly... just "performance warning"?
Does the program run ok?

Performance Warning.
