I run a single client with no intensive processes at all. No torrents, no firewalls, no antivirus software and things like that. And i have 3Mb network connection, should be enough to run the game smoothly.
no antivirus? than maybe it's a virus or a worm that is slowing your machine. im playing ryzom on 4 different machines and never experienced such issues. i think something's wrong with your PC. a graphic driver update could fix it.
