Turns out textures only get PVRTC-compressed if they are square, but Unity only complains if the size is not a power of two. So it doesn’t complain about a texture being 1024x512px, but this texture also doesn’t get compressed. The result of this is that 3 of the now 4 venues in Age of Curling have uncompressed textures. Still that’s 2x good news for the players:

1. Since the game is optimized enough to still run at great speed even with uncompressed textures, the 3 older venues have crisp textures without compression artifacts!
2. The new venue (plus future venues) can use bigger textures since we can fit more of them into the tiny iPhone-memory!
