I grew up racing Papyrus/Sierra products for nearly a decade. But I have had very little exposure to iRacing. Well, there is now a weekly series with many Nascar drivers. I have to say it looks exceptional, but I am seeing cars wink out, other cars pass thru cars while leaving the pits. Some very real damage while other collisions are ignored. Regular Fox announcers including Jeff Gordon. I think the experience of regular simmers compared to some of the real drivers(Jimmy Johnson)became apparent. there were periods of good driving with some really awful pileups caused by guys who normally wouldn't be in such situations.
