Texture Format Support

Compatibility mode restricts which GPU texture formats are available. Compressed formats (BC, ETC2, ASTC) depend on hardware, and some colour formats behave differently under OpenGL ES 3.1. The grid below maps every format to its availability in core vs compat — click a card to see why.
