BBC interview he used rFactor 2. To my knowledge is Atze Kerkhof the only driver from Team Redline who has raced rFactor2. I think it is going to be iRacing for him. http://www.teamredline.co.uk/ https://www.facebook.com/Teamredlinesim/posts/972258412797349
I think it's rF1. Old hud, old graphics engine. Bordered windowed mode... If that is rF2, it's with very low graphics settings and no HDR. It's rF1.
I just tried windowed mode to see top left logo in rf2 and couldn't go bordered window mode unlike Max. So, thinking very good chance definately not rf2.
Wondered if there would be a thread, when I watched it back I thought it looked like RF1 going by the Hud. I liked how he apologized for racing as Mercedes in game and not STR. Cool pieces on the Verstappens anyway, was a big fan of Jos the Boss so nice to see his son has big potential too. He tweeted on Sunday night he was straight back into the (virtual) driving seat as soon as he got home from Spa.
He has rFactor 2 running in what seems like a more personal type of picture while he has pcars running in promo pics/vids, and runs IR because that's what team redline races. That definetely says something about RF2 to me.
That pcar pic/video was not at his home. It was at the playseat headquarters and they made the video. I presume he tried it there and was sold on buying one with all the gear (i.e. triple screen, pedals, motion actuators, etc).
