Label not display with bigest font size

I would like to display the game title using a label. Below is the code

TTFConfig ttfConfig("fonts/Marker Felt.ttf", 96);
Label lblName = Label::createWithTTF(ttfConfig, "My Game Name", kCCTextAlignmentCenter);
lblName->setPosition(Vec2(width / 2, height *3/4));
this->addChild(lblName, 6);

But the game title display is very small although i set the Font size is 96.

I want the game title more bigger. How to solve this problem?

Should work, can you try other fonts?

I’ve try Arial font but it the same. My problem not solved.
