I am running Windows 7 Ultimate in bootcamp on a Macbook Pro Mid-2012 with Intel i5 dual-core, 3.1GHz, 8GB 1600MHz DDR3 RAM, and 128GB free on hdd. My connection type is 18MB DSL. I use this for testing my offline EO private server. With nothing running in the background (except what is needed to run the server), I get a lot of lag around large mobs. It's not as bad as the official game but still too much to play properly. What gets me is the fact that I can play other private servers with virtually no lag at all. I know it is different than running your own server but, to have that much lag, what gives?
P.S. Please don't use this as fuel for an anti-Apple rant. If your response isn't technical, you will be wasting post space.
P.S.S. I have tried multiple DBs (from Mannequin to Rainbow) with same results.
