Seems I cannot enable hardware shaders and get that pretty "perfect" mode water and terrain anymore with the latest AMD drivers. Anyone else experiencing the same thing?
An update: That's a known thing since 22.7.1, when AMD rewrote the OGL driver they also removed lots of old vendor specific extensions that sadly many older games use...
Glad to see that you got your problem sorted but not so happy to hear the reason you had the problem in the first place, and that there is no solution is even worse.
