Thanks for the reply Lax. I'm not exactly sure how much overhead ISBoxer takes but previously I was getting much higher FPS (although the computer was pretty much capped out at using 11 clients, doing nothing else). In a few days I will get my main computer's videocard upgraded and will be able to balance the load of clients a bit better. I'm hoping that helps as I am optimistic on getting this to work for my needs. I know from using previous multiboxing software with WoW that this is a process of tweaking and usually isn't going to be perfect overnight.
