Howdy all, The demo machines were a speedy Titanium powerbook (not sure which one, but it was brand new) and a G3 500 mhz iMac. Vue has been on Windows for some time, so we've added in lots of tricks to optimize it for the platform. Vue 4 for Mac OS X does support Altivec for the terrain editor, so if you have a speedy G4 you are getting some extra acceleration there. You'll see speed improve quite a bit on Mac OS X as we apply more platform tricks -- as well as more improvements are made for OpenGL by Apple (10.1 was a vast improvement over 10.0 -- we expect more to come in the next major update to OS X). n8, Im going to follow up about mentioning the Poser integration issue and Mac OS X to the home team. Vue 4 is tanned and ready, but we need Poser for Mac OS X. In fact, we need Poser 4 or better on Windows as well, installed, for it to function correctly. We are in the position of saying to CL "We are ready. Are you guys ready?". We have an answer now. Best regards, Lynn Fredricks e-on software US Business Unit
