The Age of Conan forums over at mmorpg.com are reading nearly identically to Vanguard's forums last year. "The game runs terribly!" "You do realize this is still beta don't you? It will be great in a couple weeks." blah blah blah
Being a Fileplanet member, I spent two nights downloading AoC. Only saw black screens when I attempted to log in last night. Finally made it in this morning with my resolution at lowest setting and all graphic settings as low as they can go. Knew I was in for trouble when I had lag and delays at character creation. Five minutes after hitting play I still wasn't in so cleaned house for awhile. Finally logged in and couldn't move. Took a couple steps....freeze....a couple more steps....freeze. Seeing as everything was cut down to minimum, world was just a blur. Logged out and deleted game. I could almost hear my computer rejoicing at gaining more breathing space.
Performance is worse than Vanguard ever was. Yeah they may optimize it some but doubtful it will be playable by the majority of gamers.
