Say uh, rex84... I was just noodling in Stock last night, and I did make a "discovery" with my nVidia GTX 560Ti, which would have been a "revelation" ~IF~ someone hadn't mentioned this multiple times over the course of years, but... If you have "Vertical Sync" clicked, that will cause herky-jerky jello water. Some of the additional settings, such as "Environmental Effects", "Light Shafts", etc in the left column there can also contribute, but that "Vertical Sync" almost cannot be set "On" in Stock. It looks like the vid card does not like locking to the game...
