I think readers here will be interested in a great piece by a real life engineer comparing rFactor's physics with that of a real car. An in-depth, thoughtful and insightful piece of work.

I actually discovered that by accident a few weeks ago. It is very interesting, I wonder if he'll release his work, tyre files etc ? 
I downloaded the Japanese F3 mod he used as a base for his experiments and it's pretty good as it stands. In terms of fun anyway, I have no idea what it's like to drive a single seat car.

I don't know -- probably won't release them as it's important info for other teams I'd imagine.

As far as I can figure out he's using his access to real world telemetry and a real world driver to make a generic physics model. Perhaps he wants to keep it proprietary because he can maybe make money from that ?

 

If so, good luck to him. I'm not about to argue with that.

Oh that is a shame... I thought this post was about the fidelity of the game itself... it is a great souce-game... but nearly all mods make the game run shitty and unreliable...

That's why it's used by many professional race simulators - including one or two in F1. Unsurprisingly, I disagree with your post, as it misses the point of the thread entirely.

I am very sorry to cause you this inconvenience. But the threat title said 'fidelity' which is a term mostly used for the quality of either soundsystems or software. If it the thread-title had mentioned the word 'reality' or 'simulation-capability' I also would have read it, but post a different comment.

 

I know that many professional teams use rFactor - although the pro-version. That's the attraction of, next to the excellent replay-capabilities, the modding-possibilities, etc, etc. It is just a shame that most mods run very badly on it, so that if - for example - a F1 team like Williams would sell a software package, I would not be sure that I could run it properly.

 

But I am off. Don't want to be a partypooper!

Well, fidelity as a term is correct in this instance. "The degree of exactness with which something is copied or reproduced" http://www.oxforddic...nglish/fidelity

I honestly haven't found any truly bad rFactor mods in terms of reliability, the usual issues are just early releases with files missing or overly ambitious 3D models which push the limit of the graphics engine ( and my ancient PC :)  ) too far

 

Some mods exchange fidelity for rocket propelled stakeboard type handling, and I'm pretty sure the physics of some mods are being developed by people who have never driven a rear wheel drive car. But that's not a reliability issue.

 

The Japanese F3 mod which the good doctor has used as the basis for his research runs like a Swiss watch. Or possibly a Japanese watch...

Maybe this is slightly off-topic, but: I had a look at the rFactor Pro webpage, and it talks about it being modular, high bandwidth / low latency and so on.  Does anyone know to what extent the PC game is related to the Pro system?

Roger, I believe the Pro version (which wasn't the one used in the above article) allows for much easier integration of additional engineering parameters. Bolt-in stuff for teams to run. I don't think they are in addtion to what rF1 retail provides through the normal modding stuff ... just a bit easier I think.

Some more info here (seems biggest thing is cutting the associated latency) http://articles.sae.org/12760/
