I recently decided to buy another account and try my hand at leveling two characters simultaneously. I am running two WoW clients at the same time.
When I have one of the game windows open, and the other minimized, my performance is perfect. I get great FPS and have relatively low latency. However, my other character is visibly laggy, both to me and other players in the game. This wouldn't bother me if it was just cosmetic, but it's so bad that he won't stay followed to me if I just run straight for too long (without waiting up for him).
I don't think bandwidth is the issue, because I've checked my network usage and I am not even close to reaching a bottleneck. At this point, I'm thinking that my other client is running at so little fps that it can't update the server with enough information. When I quickly alt-tab and switch between clients, I can see that my FPS is 3-4 before it shoots back up.
Is there any way to solve this?
