I've played rF2 like I am looking through a pair of binoculars and I've played rF2 like I am looking through a fish eye lens, and eveything in between (just to experiment and see what it feels like). I have a 1:1 FOV atm, which on my setup is actually a pretty wide FOV. I also have all head physics and other effects off. I still stand by the statement that rF2 "feels" like it has too much rotation (esp. on throttle). When you apply throttle and ask a car to go faster, it wants to trace a WIDER arc, not a smaller arc. Yes this can be overcome if you throttle more with power oversteer, but in rF2, it just feels exagerated with the tightening of the line. I have never driven a racing car irl and played with diff settings so I cannot be totally sure, this is just my perception from my personal experiences. I HAVE driven road cars in oversteer situations, probably hundreds of times both low power and high power cars. When you are tracing a radius around a corner and you put a lot of power down hard, the front of the car might get more pointed towards the apex, but it won't actually tighten the radius unless you follow it up by lowering the speed. Eg. throttle on hard > back of car steps out and nose points toward inside of corner > less throttle > car goes towards inside of corner. But, if you just go > throttle hard > more throttle hard, the front of the car might pont towards the inside of the corner, but the car will go wider.
Again, in rF2, you can make the car handle how you want on throttle by adjusting the diff. From my experience more diff lock makes the car trace a tighter line when on throttle, lessen the diff lock and it'll maintain the line/trace a wider line. This could be 100% correct, but I just can't draw upon personal experience with it. For me, more throttle (without subsequent lift off throttle) = wider line, not tighter line.
