Thanks for your response. I was reading the Recommended Video Cards
for ArchiCAD 16 on ArchiCADWiki. It states "we have also good experiences
with most of the standard Nvidia cards, somewhat worse experience with
AMD/ATI cards". I know a lot of MacBook Pros come with AMD cards.
I'm glad to here that yours is working well. The machine I am looking at
(a Dell Vostro) comes with an AMD Radeon. I'm really tempted to by it, but
Graphisofts "somewhat worse" statement is giving me second thoughts. Anyone else have experience with AMD Radeons on laptops (windows or Macs)?
