  válasz Sárpac #13045 üzenetére

  hol csináltak ati teszteket csaló driver használatával a több fps érdekében a grafika rovására?

  Dx10.1 shader 4.1 pedig parasztvakítás nincs értelme ezért nem is került bele az nv karikba

  hehe, pedig még a legelején pont az nv pattogott miatta, hogy milyen fontos is ez. aztán még egy normális DX10-es (MS DX10 API szabványnak megfelelő) karit se tudott csinálni és inkább a játékfejlesztőket kente meg, hogy G80-ra írjanak.

  aki G80-ba vagy G92-be fektet, az a technikai fejlődést akádályoztatja azzal.

  de ha most arra gondolsz, hogy az RV670 technológiai újításként csak a DX10.1-et tartalmazza, akkor nagyon tévedsz:
