It seems that textures marked as npot are loaded in their full uncompressed size into ram?
When i build an executeable (emtpy scene) it uses up 36mb of memory.
When i add three 2048x1536 textures (marked gui npot compressed 1,5MB.) the same executeable will suddenly take up 84MB! of memory!! The difference (48MB) is exactly the size of 3 uncompressed 2048x2048 textrues (16,7MB * 3)
When i change the the texture settings to advanced and change the textures to pot the memory usage decreases again to 40,5MB which is 36MB + 1,5MB per compressed texture.
Is this a Unity Bug and can I do something about it?
