New improvements

The graphics have improved somewhat. But what is more important is the handling of the vehicle. You can now take countermeasures, which was a bit difficult at Formula 1 2012.
But what is also a very good plus point is that while you're on the track, can save.

Some drawbacks I would still like to mention.

Just a pity that you can save this only on the race track and not during a pit stop. Thus, you should save only briefly before a long straight line, otherwise you will again struggle to find back into the game.
Games I only do the Career Mode with 100%.
If you want to return to the Boxe Quali Fing, still appears a loud roar of the engine for about 1 second. You could certainly do away with a patch.
Furthermore, I found the damage model is not implemented correctly. If AI accident each other, I was there not involved, an AI opponent has completely lost his front wing. The result should be that he immediately moves into the box. But is not he, but could continue to drive good lap, partly with the fastest lap. This is very unrealistic.
The Saftey Car I (completely at 100% setting) not been seen by nearly 8 races. Failures of AI opponents also very rare. So. about 3 in the 8 races. In reality, this is more common.

Compared to Formula 1 2012 a purported to improve, but unfortunately but with minor errors. Hence only 4 stars.
