Thank you very much for all your information on Regent level in Civ 3. I also bought Civilization 4,but when I start a game,the computer says:"Your machine is below recommended specifications.The graphic settings were altered to accomodate this,however,you may experience performance issues". I thought the requirements were met:2.66 Intel Pentium 4, 512 DDR SDRAM memory, 128 MB NVIDIA GeForce 4 MX440 graphics card etc. I downloaded a patch. What is wrong ?.
