This game works with no issues until I get to the open water. I know people have mentioned this before. I am running XP, Graphics is NVidia GEforce 6200, 512 MB Ram, Processor is Pentium 4. I think it's an issue w/the updated graphics card. People have posted making changes to the graphic settings. Please tell me HOW to make these changes and which ones to make. THanks

Setting water detail to low should resolve the problem (there should be an other application it the game folder that you can use to modify these settings), you can also downgrade to (very) old drivers (look for my post in the tech support forum regarding this issue, I know I mentioned the driver version that still works somewhere).

Try this...
Artifacting and/or texture flickering - Go to the settings application in the game directory, click on the advanced settings tab and uncheck the box for HW Vertex Processing.

THANKS SO MUCH!! IT WORKED.
