Motogames TV, a site out of Poland that does a lot of these comparison videos, has posted one of the new Race 07 version of Mid Ohio that was included in the GT Power Pack. They've compared it to Virtua LMs version for rFactor. Virtua LM is known as one of the top track developers for rFactor. 

Check it out and you make the call. Which is better ?? iRacing should be the one to compare to in my opinion since it's laser scanned.
