Answer 1

Be aware removing the delay means fullpabe.js will be making hundreds of operations per second when resizng, as the resize event gets fired hundreds of times. That's why the delay exists, so it won't consume machine resources like crazy for such a basic thing.

You can reduce the number, but I wouldn't encourage you to completely remove it.

Modify the fullPage.js version 2.9.7 line 2150 a change 350 for 50, for example:

resizeId = setTimeout(function(){
    reBuild(true);
}, 350);

Change it to:

resizeId = setTimeout(function(){
    reBuild(true);
}, 50);

Answer 2

You may initialize the plugin method doneResizing(); in $(window).resize(function () {})
