Regarding the game itself, particularly in relation to F1 2010:
+ Modeling suspensions is a real plus
+ Opponents are more swift and "intelligent", but there is still room for improvement
+ Circuits are beautiful, however a flats on some circuits (Monaco, Canada) with slowdowns sometimes very troublesome (my PC is also not totally foreign to it)
+ Tires are properly modeled, wear and temperature have a real influence on the steering
+ KERS and DRS are perfectly integrated
+/- Safety car is a real plus, but too box (automatic braking to avoid exceeding its competitors, for example)
- In terms of lap times: it is generally quite consistent, but there are areas with improbable differences (2 to 3 seconds less than the top teams in Difficulty "professional", with Williams!)
- Collisions are improved (carbon flying everywhere, the muzzle is destroyed), but it is still very (very) far off
- Penalties are too severe and not always just ... frustrating.
- Replays are beautiful but again frustrating not change the driver to track what happened!
Finally, a good opus (14.5 / 20 for me), despite some bugs (a fatal facing an invisible barrier crash while I was driving in the arrival of the stands) and areas for improvement.
