PPU vs Scale

[Chris-Trueman]

I’ve been searching the internet for a while now looking for answers to my questions. Most information I find is about pixel perfect and that isn’t my goal.

Is using scale harder for rendering? Scaling requires an algorithm to put the pixels where they should be. Is that same algorithm performed if I use PPU to scale my sprites? Does it have any significant performance impact? Is it even worth the bother to worry about this?

Does it have any significant performance impact?

I don’t think it would matter Here’s why:

PPU just says “at import, using unity scale, consider each pixel to be this big,” so it’s not really a runtime operation.

Scale is computed at runtime, always, even unity / identity scaling.

Thank you, that’s good to know. Should have been obvious, makes sense once I remembered how those pixels are projected on to the screen.
