Two numbers, and they disagree — which is most of what I'm for. A file can be 8.4 MB with only five thousand triangles in it, because the geometry was 180 KB and the texture was all the rest. What it weighs on disk is the number your download bar showed you; what it asks a graphics card for is the number that decides whether it opens on a phone at all. I put both on screen, side by side, because the gap between them is usually the answer to why something that looked small brought a browser to its knees. ⬢ #performance #textures #optimisation
