Choppy water

[PrEZeX]

Hi,
Is there anyone who finds the water in SH5 choppy? I don't know how to better explain this but the water seams like its skipping and not fluently passing by. I don't think its because of my hardware but who knows. I'm running the MMM mod (http://www.subsim.com/radioroom/showthread.php?t=192236) and using antilag (2 frams ahead and 38 FPS limits) with 1920x1080 screen resolution and all settings on max. My specs are:
Windows Ultimate 7 (x64)
Intel I7 960 @3.71 Ghz
12 GB DDR3 ram
4 OCZ Vertex III SSD disks (2 in raid1 for OS, 1 for games and 1 for pagefile)
HD6990
Asus Xonar DX soundcard
No problems with heat or PSU (1kW)

So can I somehow get rid of this "choppines"

Thanks in andvance!
