Using atlas, we can reduce memory and draw call. And the atlas is usally POT(Power of Two) Texture.
And I know non-POT texture have a lot of GPU and memory performance overhead. (link)
I have many rendering objects and they have also their non-POT textures.
And I packed the images into one 1024*1024 POT atlas and applied them to the objects.
(each textures is non-pot, and the atlas is pot texture)
In this case, Can I avoid non-pot texture overhead?
Are they treated as non-pot texture or not internally?
