Racer with the most realistic road/weather effects? (PC)

Can you recommend me a good PC racer that has very realistic road and weather effects? I am currently playing NFS Rivals and the graphics and physics are amazing. Can you suggest another game? Thank you.

DiRT 3.....

F1.....

I'm not trying to start an argument here or anything, and I don't want to sound like an elitist jerk but....NFS is NOT even close to realistic physics. Fun and good looking, for sure. Now, if you want realistic, you are asking for a very different experience than NFS. Just warning you...you may not like it. F1, as @Lulu_Lulu said, may be a good place to start, since I believe you can customize it. Start at arcade (which is where NFS would be)and work your way up to full on simulation. Assetto Corsa and Iracing are apparently very good (I'm a Gran Turismo guy, but a lot of my online racing buddies talk about those two games). There is also a new one, still in testing a bit, but it is free to play and apparently quite good....it's called R3E-RaceRoom Racing Experience. Hope this helps!

@benandmax:

Its true.... NFS has never been realistic..... evrn when they actually tried to be with Pro Street and Shift
