Can I run 3 instances of Guild Wars?

I already have the capability to run 2 Guild Wars clients, but I have 3 accounts.

How can I run 3 instances at a time?

Yes, you can, provided your PC can handle 3 clients.

Guild Wars Multi-Launch

that oughta do it

I know that Matty's Guild Was Multi Loader works with 5 copies at a time, although you will probably see a performance hit with that many open, you should be able to run 3 on a "modern" machine with no performance hit though.

Just make sure that you minimize them, even my beast has trouble running just two copies when they're both open on different monitors. I also take a rather big (45-50%) hit when I'm running two on the same monitor, but one isn't minimized.

i have a prety nice laptop (was really good when i got it a year ago) and when i load 3 i can hardly move with out rubber banding all over but you can open them.
if you want ti jus to trade then it works but if you expect to play with 3 open you wont be able to unless you have a really good gaming comp

A play with 3 open on a pretty average laptop alot of the time, i dont get any fps issues

Guildmate of mine runs 8 accounts at the same time

I used to run 2 instances of GW on my last PC, (AMD Phenom I 9850 Quad core at 2.5ghz, HD4850 GPU & 2GB DDR2 RAM) - I had virtually 0 FPS loss, 3 was perhaps 5-10% performance loss. I've since upgraded my entire system, to something more powerful, but I haven't tried loading multiple copies of GW since then.
