Has anyone else suffered with framerate issues on the opening/starting point on st.Lucia?. My comp has 3.2ghz p4 775 processor, 1gb ddr2 ram and an ati x1600 512mb ddr2 graphics card. It runs assassins creed without lagging and that is a resource hogger, but virtually siezes up on st.Lucia...any ideas please...this mod looks terrific and I cant wait to play. Many thanks
