Tried three boxing last night just to see if it was both possible and playable however I ran into some problems running three clients on one comp.
The main problem was the constant HD accessing plus the extremely long load times. Normally this game loads zones really quickly but with three clients - even zoning one at a time I can be sat with an empty load bar for 5 minutes or more. The Marketplace is especially bad.
I'm running one client on each monitor in the lowest possible detail setting and its practically unplayable. My machine is no slouch - I can run 4 Everquest 2 instances with no lag, slowdown or time delay in zoning - zoning all clients at once easily.
Has anyone else tried this and found a setting which runs things adequately? I'm not using any scripts and whatnot to run my toons, just using the other accounts to get some xp, more loot chances and farm guild xp drops when things are quiet.
Game looks really cool on three monitors when I'm just running one client by the way
