abaris - the problem isn't with nvidia or their drivers... the problem is solely on the shoulders of EA here, nvidia's drivers are tested by microsoft and shown to work... ever notice EA never makes any similar claoms about their software?
Oh, actually I'm a big fan of Microsoft's flight Simulators and nvidia isn't able to provide working AA and VS for these apps for quite some time now, although they know about that problem.
My solution will probably be to run the ATI card on my stronger machine and the nvidia one on my second as a Sims only rig.
