Ualaa, thanks for the tip. I tried that out and the CPU graph was bouncing around a fair bit but its always over 80%ish so I think it has a lot to do with it. Is there an easy Performance counter to check the graphics card?

Alcattle, thanks for the tip. I have already dropped all the graphics settings to low on all 5 clients, then increased the view distance on the main screen (trying to play with the minimum view distance is annoying ) The only thing I can do now to increase the speed would be to drop the resolution I think. To be honest, its playable the way it is at the moment. I'm planing to build myself a new computer for christmas so that should make things a lot smoother
