Посмотрите работу с Voodoo 5500 а потом с какой-нибудь картой от nVidia. Думаю, после этого вопросы отпадут.

Although supporting TnL out of the box, performance increase is less than stellar and given the lack of certain capabilities in the driver set and requirements for correct operation of the game, Comanche Hokum can not be recommended as a showpiece flight sim for nVidia TnL. There are problems with certain GeForce/nVidia cards being unable to draw 3D lines with TnL active. Thus objects containing lines such as power transmission towers and radio masts remain invisible but are still "there." This seems to be a limitation of nVidia drivers. nVidia is aware of the problem but no timetable exists for dealing with it.
