I have been wondering the differences in lighting more then anything with iRacing over rFactor so I borrowed my friends account for testing. I am sure the windshield in the rFactor version has affected the color as it seems awfully dull. I also mistakenly removed ALL head movement from rFactor when I should have left some. Used the stock iRacing cockpit view with the FOV on at its lowest single screen setting (45 H) so to match I set rFactor's FOV to 28 Vertical dictated by my screen. Math is fun. Also I set rFactor to 12 noon but the sun seems to be in a different position than iRacing. Not sure of the time in there. I recorded the iRacing version first and played the lap back on my 9" netbook. I eventually figured out to wait 5 seconds after the ir video to try and copy it. What a pain!
