[Why did remove useFrames property in gsap3]

Hi, I'm still using gsap2 because of useFrames.

The web app I develop is served on row-performance device. So, when I use tweenLite in gsap2, useFrames is nice option to improve the animation performance.

I know gsap3 is cool, but I can't level up gsap. T_T

Any special reasons? Are you considering adding it?

Thank you.

Thank you for your replying.

 

Then, I have a question.

I understand that ,even though I fixed the fps to 20 using TweenLite.fps(),  a scrolling animation make a fps changing.

So, I think when a container scrolling, fps is under 20, otherwise fps is 20.

 

I checked the fps timeline and scene with the screenshot function on the performance tab.

Then, when a container moving(scrolling), fps is about 20 ~ 60, otherwise fps is about 20.

Rather, fps is higher.

 

Why is that?

I use TweenLite and useFrames:true for scrolling caroseul UI(lists of images).

Also, because of low performance of environment,  use TweenLite.fps for setting fps as 20.

 

when deveploping, I often use a performace tab of Chrome development tools.

For a performace test, after recording performance, I expected a flat timeline graph line.

However, the result is a rugged line.(min: about 20fps, max: about 60fps)

like a below image,

 

when this carosuel UI scrolling, component mounting(image components), image lazy-loading, scrolling animation and image scale-up(transform) are done together.

 

Why is the fps not constant?

 

Thank you.
