15 degrees of freedom physics engine

I ran across this in Wikipedia (rFactor) and wanted to know more about it. Is this what makes rFactor feel so good or is this old news and all other sims have twice that or something better?

I already looked it up and understand the math but wanted to know how rFactor rated with other Sims in this area because its kind of old news now is all?

 

You want enough to cover any many systems as you feel you need (the whole thing is tied together). More is generally better but it also comes down to how you apply it, and how well you apply it (can still make crap mods for rF2). But it's also a PR exercise, people love numbers.

 

Here's a presentation by the man himself:
~85 DoF @ 400HZ (around 27:37)

 

^^^^^ Marvellous video , great insight to the history of game .
