Fifa 15 has indtoduced some changes to all model textures.
The most important one is that all textures have doubled their sizes.
Face textures are now 1024×1024, ball textures 1024×1024 and boot textures 512×512
The second one that i noticed is that they introduced a new compression for the normal maps. From now and on the normal maps will be compressed with -BC5 compression. This is fairly new type which is probably optimized for normal maps and with the latest versions of DirectX.
