Interesting. Having said Westwood games don't like AMD's can you point me in the direction where I can read a little bit about it? It's certainly news to me. I own just about every Westwood game written and I have no problems with them at all. Yes Emperor is Westwood's first effort into the realms of 3D but surely it wouldn't favour a particular CPU? If that was the case I would assume the game favours MMX rather than 3Dnow! instructions? Whatever the problem is the last mission and basically any scenario which involves a large number of units makes it unplayable even on a low graphics setting which I think is utterly ridiculous considering the power of my system. For now I'm walking away from it until Westwood address these performance issues. Definitely not up to Westowood's usual impeccable standard by a longshot.
