Not 100% sure yet on if Velks may be instanced, but you might want to look into that as well.

I haven't had to instance any of my farming locations yet 'cause I'm a pally and 7-8 mobs is all I really feel motivated to pull at a time anyways. If you can get your own instance, it may be worth the cash just to find out if you have the zone to yourself.

As summarized quotes have explained in other posts/threads, if nobody can see you training more than 10 mobs, nobody will really care, and you can run wild through the castle. Out of sight, out of mind type of thing. However, it is always a good idea to check /who to see is in the zone before you assume you've  got the place to yourself. Check it regularly. Don't want to be surprised when you're in the middle of beating down 30 mobs and someone walks up to you and starts just staring at you. They might as well have a little red light blinking above their heads indicating their fraps is running.

On a side note, I've run into multiple people training well over 10 mobs in Velks, and I've passed on by and grabbed what left I could find. I'm usually approached while I'm killing my 4-5 mobs by said individuals, usually freaking out because they saw me run by and they want to be extremely nice to me in fear of getting banned =P

I gained a couple FG pieces that way LOL

May try opening the "Options" button at the Login screen when you first boot up EQ. Pull everything down, and if that doesn't seem to work, you may want to look at SoD (Seeds of Destruction), as it comes with some features that aid in multiboxing and/or using a dual core processor.

My apologies if these solutions were offered through various links in the thread. Currently at work and cannot open them to view contents due to corporate firewalls.

I found that manually limiting your frame rate per box to 24-30 seems to help in certain situations. Have you tried that yet?

I've been having a problem since I've started that if I don't have enough going on in the zone I'm in (for example, GI lower Guk for FG pieces) then I start running super fast and my character skips like 10 feet at a time and it's hard to turn or direct yourself correctly. I changed my frame rate down to 30 and no longer experience this problem.

There's a million settings to look at, and it may take some fuddling around to get it right, but I hope you find a simple solution that will ease your woes with lag.
