Format Basis Universal zapewnia wydajno\u015b\u0107 na poziomie natywnych tekstur GPU, ale zapewnia wy\u017cszy poziom kompresji.
\nBasis jest formatem po\u015brednim, zapewniaj\u0105cym szybkie przetwarzanie do r\u00f3\u017cnych niskopoziomowych format\u00f3w tekstur GPU, u\u017cywanych zar\u00f3wno w systemach stacjonarnych, jak i urz\u0105dzeniach mobilnych.

W przysz\u0142o\u015bci planowane jest wsparcie dla formatu ASTC (RGB lub RGBA) oraz tryb\u00f3w 4\/5 RGBA dla formatu BC7 i 4bpp RGBA dla PVRTC1.<\/p>\n
