This is the most up-to-date and the best combination package you could ever use to play quake in true High Definition with special effects. This mod has many textures, progs, and effects from Rygel, Seven, Ruohis, Moon[Drunk], etc. The engine is done with the latest Darkplaces mod as well. It took me years to combine them all into their respective pk3, pak, and autoexec.cfg files. There is no need to patch or run any kind of vispatch for water effects. Just drop in your registered PAK0.PAK AND PAK1.PAK and your good to go!
