I think this has been reported in a few different ways previously. I am hoping that someone can come up with a solution. ? It's ruining the game By the last third of a season race (100% distance) the Ai are lapping quicker than the start by about three to four seconds. I accept this as track rubbering in and less fuel. However, my own respective lap times are only about 1 or 2 seconds quicker on average. This meaning when i have a healthy lead or track position i find myself having to defend aggressively, then watching cars i have lapped trying to unlap themselves. The final 10 laps a car that i was pace matching mid race can finish 20 seconds ahead of me without my laps getting any quicker! To get around this i am now doing a mid race save when i notice the Ai speed increase happening significantly and then reloading the race on a lower difficulty level. This actually works out about right for race pace. But it's not right!! What setting in the game files controls the Ai speed increase during the 100% race ? is it gradual grip increase or speed increase or what? Can this be modded to make the final Ai lap time speed the same as mine? Do the Ai actually have to manage their speed for fuel saving? I have read replies regarding this before about my tyre wear and strategy but i have tried different approaches all with the same result !! Any help much appreciated!!
