Yes, I have that problem as well, little blinking white lines on the horizon and the water. But mainly, I'm annoyed with the twitching water around the waterline of everything.
I tried disabling Water Stream, and 16km Environment (the only 2 mods enabled that I think would change the water). But to no avail.
What is the best way to update your drivers? A few people have suggested that I do this, but I'm not entirely sure how to go about it. Should I update my Graphics? I have an Nvidia 8000g, but I didn;t se this model listed in the Nvidia site, and Its a new computer.
Thanks for the help, I finally got all the mods and stuff set up, and this bull happens



Thanks Again
