I'm not seeing the connection? Or rather, the relevance.
Okay, okay
I'll elaborate.
I have seen people, here and on other forums as well as on WMD forum, saying that Richard Burns Rally is a good simulator and that pCARS is not a good simulator and will never be.
I can't give any comment on the quality of neither RBR nor pCARS as I have not tried any of them.
What strikes me as odd about the sentiment that pCars can't be as good as RBR is that the physics model used in RBR was by pCars forum members and Slightly Mad Studio found to not be good enough. So work began on a new model.
In the following I will make assumptions based on my limited knowledge in simulations.
I have a little bit of experience in regulations, and this is somewhat simular to simulation.
Once I did a regulatin job on oxygen levels in a tank with bacterias, this was a pain in the... because I had no idea of how the underlying model was. Suddenly the levels would rise for no apparent reason, and when I cut the air supply to the tank the levels would fall slowly as a leaf from a tree. So I had to make a lot of fuzzy logic around my PID regulator that would change the PID parameters based on other parameters.... What A Mess.
No to case number two. Regulation of RPM on a boat motor. Here some smart professor had made a mathematical model of the process. So all that was needed was to fill in the technical data of motor, gear, shaft and propellar, and behold; the PID parameters would fall out of the equation. (If you also get a warm fuzzy feling when stuff just falls out of models, yep you are a nerd).
Okay back to my point.
I belive that in a simulator the most important thing is the physics model.
I have been following the development process on pCars on the pCars forum. With the original BTM it seemed that they started doing logic around the model to make it work. This reminded me of my experience with the oxygen levels.
With the new Seta Model I am reading a lot of: this and that should fall out of the model.(Warm fuzzy feeling again.)
Disclaimer: I only have a bachelor degree in engineering, and this car simulation stuff is on a PhD level, so I might be completely wrong. If someone who reads this can tell me so, with arguments for why, I would be very happy
