The real question is, how much more powerful of a computer will we need for this. I have a pretty darn good computer but, even I struggle to get a steady 60fps on some of the newer tracks and newer cars. The spray, rain fall, and dynamic changes to the circuit will surely make that even more computer power needed.
I personally don't see them implementing rain conditions in official series but, I could definitely see it being something used as a league or hosted session tool. Too many members would complain that having unpredictable session weather in official sessions. I'd personally like it because it would require people to make much more conservative setups. With the weather being set, we can setup the car to be best in that condition. We can run a much more aggressive setting on the car because we know what the car will do every lap. But, once we get wind, temperature and air density changes during a race, we would have to switch to a safer more predictable setup. Which is realistic to what is done in real life.
