Here is a very dumb thing but, you can always sacrifice the water, like disable all the fancy things and lower stuff for the water, I never see a difference, else then inside the water, that with it on maximun my game runs like crap and looks uggly, in minimun it doesn't lag my game anymore and it looks nice...
I will do some testing if I can, but do tell, is it for Fallout 3 or New Vegas? And a link for it, since I see billions of ENB's with that same name.
