Performance issue when 1000 tweens are started simultaneously

[purna-spill]

I set the tween capacity to 1500 before playing an animation using PrimeTweenConfig.SetTweensCapacity(1500);
I am calling Tween.Scale(transform, endValue: 0, duration: duration, startDelay: delay, ease: Ease.InQuad); for 1000 different objects and frame time increases to 7000 ms.

Am I missing something or this is the limitation of PrimeTween?

Hey,

PrimeTween can start 1000 animations at the same time with ease.

In my tests, MacBook Pro M1 can start 100.000 animations in 5.76ms. I also just tried the same test on Google Pixel 3a, and it takes 67ms.

Can you please share your code? Is there a chance you're creating 1000 objects at the same time you start the animations?

Hey @KyryloKuzyk,
You are right, performance is fine. It's just because of PRIME_TWEEN_SAFETY_CHECKS Scripting define symbol. With this symbol, performance was dropping significantly when 100s of Tweens are started simultaneously. I faced this issue only in mobile devices and not in MacBook Pro.

Thank you.

@purna-spill Yeah, PRIME_TWEEN_SAFETY_CHECKS performs numerous additional checks and saves stack traces of each tween, which is quite expensive, especially on mobile devices.
I should probably add a warning that this define should only be used for debugging because it negatively impacts performance.
