Re: [JAVA3D] Graphics card

Hi Andy Well the question is if you just want a card to develop with Java3D either GeforceIII nor ATI R8500. Both are overkill and support features which we will only see in J3D 1.4 which is accordingly to the latest schedules at least 1 1/2 or 2 years away. EOF, J.D. -- Explore SRT with the
