Side by side comparison...

I realize iRacing is not for everyone. There is good and bad but in my opinion the tracks are second to none. Take a look at this video.

It would be better if the steering wheel and driver moved in the replay but you get the idea.

I have to agree the tracks ARE second to none.
But it's not just the tracks..the car physics and net code are also light years ahead of anything else I've tried IMO.
It's so amazing to see the difference in these laser scanned tracks compared to what we thought were accurate tracks in other Sims.
