Randall - do You mean going back to original shader ? I had the same issue - drastically deteriorated quality of water vs original state after installing shaders 3 (having REX) - exactly the same as mentioned in the beginning by MichiMaster11 - so I removed shader 3.0, went back to original waterconstants file, flushed cache etc. so I did all steps back and ...what a surprise ! - I still have these very bright and with a low resolution waters, maybe not exactly the same as with shader 3, but this low resolution (in low 3-4k ft flight) somehow stayed and is really annoying, because I like low & slow flying especially over coast areas... checked fsx.cfg if some Bojote's suggested lines are not left, but now have no idea what is still wrong...
