Choppy after 15min

[slouth]

First off Thank you to everyone who has had a hand in the project, I almost had a tear in my eye when I loaded this up for the first time on the weekend. The music, acutally seeing people in Kelethin, OMG it was so exciting...

I started EQ, about 1 month prior to Kunark and played on and off till sometime during PoP. I had a 65 Shaman, and 65 Rogue.

My basic problem... I created a ranger just to do some exploring around Gfay. And after 15min or so I get super choppy/laggy. Im not sure but I think it might be a result of the multi core processor, I tried the run in 95 mode, Game would give me an exception error loading, I then tried dropping it to 1 core through msconfig, and it gets choppy still, and thoughts ?

Amd X4 9150 processor
8gig ram
Vista Prem
built in Video card (lol whens the last time I could play a come with built vid)

Once again thank you all, and I'm so excited to play, although i might have to make a shaman or druid for the soloing ablitiy !!!!
