To be clear on this subject: There is no mod that will (or indeed, that actually *can*) resolve the issue with 'late-model' AMD graphics cards which by design must use newer drivers. It is (apparently) the newer AMD drivers that WOFF doesn't work with.

(JNHoward, you are correct: Your newer AMD GPU is not supported by drivers released before it actually existed).

As an aside, I've watched closely to see if AMD shows any sign of changing anything to fix this, and regretfully it doesn't seem they are, even though it's a 'known issue', having been originally reported almost a year ago, and reported by OBD ~5 months ago.

As a suggestion, if discussion is to be had concerning mods specifically as regards river textures, it might be best to state that these mods don't resolve the issue WOFF has with AMD cards. (Unless I'm mistaken, none of the mods resolve that issue; not much sense giving the wrong impression).
