Using Bigger Sprite vs Upscaling GameObject

Unity Engine
1

Hi
It is a 2D game.
There will be enemy characters with many sprites for animation.

Which is better option?

1. Using 256x256 sprite and upscaling the game object by 2
-Saves file size.
-Quality not affected in my case
-does it affect performance ??

2. Using 512x512 sprite itself.

I use sprite altas - Sprite Packer of Unity.
In First case i save file size of my .apk. I can pack more sprites in an atlas. My characters are 3d rendered sprites. Not pixel perfect. So i do not notice any difference between 512x512 sprites and 256x256 upscaled sprites. But does upscaling affect performance ? I cannot notice any change in unity stats when running the game. But does upscaling affect performace ?

Nope. The act of scaling it obviously take a little tiny bit of cpu juice, but once it’s scaled that’s the end of it. If you can rock 256 images instead of 512, awesome. Do that.
