I'm just barely scraping by technically and probably way over my head with the mod additions, so I got excited when I saw the OP. Unfortunately, I'm having the same issue and ask, most humbly so as to not upset anyone (see earlier posts) if anyone has successfully dealt with this by deactivating mods and, if so, which ones? That would be a constructive response. Thanks so much. Ps. I'm running this on a standard Intel DualCore iMac partition, so no fancy cards and I haven't messed with any graphics settings. I have no mods that modify water.
