We're flipping the situation around here after Lime Rock. Now it's rFactor 2 with the older version of the track.
I do prefer the iRacing version. Much more runoff and less green suspicious stuff at track edge. The track is narrower here, and it has a vicious chicane at the end, which really cramps the car up.
But it does answer a question I've had for some time about the iRacing version. Quite often in a couple of areas of the track - across the start line towards turn 1 and the left hander before the hairpin - I've noticed drivers take a wide line. Having driven a little bit here I can see why. With the new layout I still think a tighter line is faster, but you can't get away with that here.
As far as the quality of the graphics ... where it loses out there it gains in frame rates. It's definitely a track that would benefit from an update as it does look dated. But it more than gets the job done.
It will be interesting to see how the two works in rFactor 2 down the long back straight, and how the A.I. handles the chicanes as well as the hairpin.
