So, Tiger needs rev2.0/3.0 shaders? Ok so basically a dx9 class card. The 9200 has rev1.4 shaders (dx8.1). Why not write backward compatible shader programs for rev1.4 too? Game developers sure do..... Are Apples shader programs really that long so not to fit in shader 1.4? Can they not achieve similar results with smaller shader programs for less complex Tiger tasks? What gives? Tell me if i'm talking rubbish!
