Re: Il existe déjà des formats libres; le problème c'est le support matériel.

Matériellement ou pas, si l'on en croit un des dévs Intel :

None of our currently shipping hardware has native support for ETC2, which means we have to implement it in software. That means that textures are uploaded and stored to the GPU in an uncompressed format, which isn't terribly efficient, but there's not much else we can do. That will at least make applications using ETC2 compressed textures work.
