Witam mam pytanie chodzi mi o zaawansowne technologie stosowane w kartach NVIDIA i ATI czym one sie roznia i ktore sa lespze co daja ?
Moze ktos ma jakies porownania albo cos w tym stylu ?

truform jes ttylko dla ATi, nVidia nie przewidziała takiej opcji (z tego co mi wiadomo). właśnie dla truform zmieniłem grafę na ATi.

a co daje te true Form:P??

80.53.11.* napisał:

Trueform korzysta z geometrii powierzchni wyższego rzędu w celu generowania bardziej naturalnych i zawierających więcej szczegółów powierzchni terenu oraz postaci w aplikacjach obsługujących tą technologię.

No właśnie,obsługujących.
Gdyby to było robione sprzętowo to byłoby spoko,
odpalasz giere,widzisz że masz płynną animację wiec zapodajesz dodatkowo więcej trójkątów w obiekty i lux

a to szysztkie giery maja?? czy tylko niektore?? bo jeszcze nie widzialem gry ktora trueforma wykorzsytuje:P no moze unreal 2004 ale tammm tego nie widze jak mam to wlaczone:P kurde nie umie pisac zdrobnien cos mi klawiatura pada:P

nvidia tez ma swojego trueforma tylko inaczej sie nazywa
trueform jest juz w dx8 np demko ati trueform cos tam chodzi na gef4ti i tak samo dobrze wyglada , wiec nie marudz
