i'm sure ISI is working on this, like they always do without telling us and following their own agenda, while we are whining about it. Like (i think it was Tuttle) said before this game/sim is all about physics all graphical features are just layers on top of it. Don't get me wrong here i do love the rain as shown in the vid from way back and Project Cars does it better right now but in the end i think ISI will show us how they think it has to be done. Just stay humble waiting on improvements on this and in the mean while enjoy what we have already, and that is a lot imho. my 2 cents carry on.
