Kind of an odd poll isn't it?
Your system is no issue here. I'm struggling with the same issue myself. I ended up turning Ocean detail level off and Ocean grid size above medium. Average FPS now lies at 50FPS, but at some camera angles it forcefully stutters. Also make sure Anti Aliasing is set no higher than 2x or 4x at max.
It is best to turn AA off within SSE's own settings, and instead, turn in on within your Catalyst Control Center.
For me there was some performance improvement when my GPU started doing all the work.
