Assetto Corsica sounds better though
Seriously, quite interesting list, nothing to add at this point...

Quote from Neilser :

I guess maybe it's too late to start now but having the reference links in the OP would be cool.

I thought about that back in 2009 but by that point every google search for "racing sim physics rates" simply brought up this thread or people talking about it. I suppose I could at least make the ones I found today links, and I can search this forum for some others. Will do that later.

Quote from Neilser :

(NB: in case it wasn't a pun that sailed over my head, it's Assetto Corsa & assettocorsa.net, not Corsica )

Oops, fixed!

What about DiRT Rally and DiRT Rally 2.0? I've no clue where you would get the info about it though...

I've just been using Google but no success with Dirty Rally or RBR. Depends if a developer has ever posted the information somewhere. The information often either seems to be promoted or kept secret.
