First, apologies for my bad english.... i agree Willf about the altivec. And it seems that poser don't like networking very much. I use a cable modem and i have to disabled tcp/ip to get the full speed, ot it will crash. Remember also that poser seems to be developped under windows, and ported to MacOS, so some of the code are not very well implemented. And if the New G4 is really powerful, some apps don't work well with it... In some cases, a G4/400 is slower than a G3/400. About he video card, the ATI shipped in the G4 is not as good as it seems. Another Video Card can have better performances...
