As someone who has developed dirt oval content for rFactor over the past 8 years, I've been doing a lot of research to try and find out how much has improved as far as dirt from the original rFactor physics engine. Dirt is pretty much non-exsistant in rFactor, rFactor dirt/rally tracks are basically just asphalt track TDF files with dirt textures over them. I'm really hoping that someone can tell me more about this subject, so that I know if it's worth it or not to move from rfactor to the new Automobilista title.
