The water simulation I have built has finite water and also simulates pressure correctly, as demoed in the past. However, on the downside it is infinitely elastic (a single drop will spread over a large plane, like oil in an ocean). The rendered water also does not correspond 1:1 with the actual water volume, so it can look buggy. And there are still a few minor bugs as well.
I noticed that it seemed to spread laterally much quicker than it dropped, which looked odd. I imagine modeling water in a performant and semi-realistic way is rather hard.
