The biggest improvement probably lies in the revision of the driving physics. It now seems more realistic, but also challenging to drive. The car reacts much more sensitive and the first few races felt almost like on a wet track. Did you look at first accustomed makes driving a lot more fun than F1 2010. For this, the rule changes as KERS, DRS and the new tires come. Overall, it must / can now go very tactically. You can use KERS and DRS to optimize lap times, or to push extremely in certain areas. Overtaking is thus actually easier. The tires go faster broken but the "Super-Soft" really fun and allow for faster lap times.
Some things that its predecessor lacked were now included, such as the safety car. Toll also statistics relating to the player, such as ect the total number of laps, kilometers. Had quiet can be more detailed yet. The interviews are still there and just as annoying and pointless as it was then.
The differences between the teams are now much greater. If one drives eg for Lotus has one first effort to follow the safety car, while you can fight for the lead in Williams already. As one might assume, the units should be the top teams as well as for 2010 slightly (in career mode)
Rather Nagative noticed is the new balancing. If one drives eg in all three trainings at # 1, you can get so large in qualifying problems that you may be glad to reach Q2. This applies in particular to rain. Here the car is hard to keep on track even with rain tires and rain Setup. If one has groped the limit of the car is still missing 0.1 seconds on the penultimate place. Presumably wet race one gripe from 2010 because they were too easy. Now they are much too heavy.
Quite different at the start. If you have messed up qualifying and is in last place, you can in the race traveled after two or three curves ancestors in 10th place until pulling apart the field. To react quickly in the first round, you can drive up in 5th place. So qualifying is almost superfluous. Starts are now too easy even if the behavior of the foe is now more realistic.
About the technology: The game has massive memory problems. Vehicle setups are not saved correctly. Various settings such as gasoline mixture or aerodynamics are sometimes not saved. Settings can also be changed. You have set in the setup as gasoline mixture 3, one mixture has on the track then 2. You always have to switch manually. Steering wheel settings are only automatically GpsDrive when you start the game by pressing a button on the handlebar. Saves MASN a vehicle setup, you have to conclude the current session, otherwise the setting will be lost.
Scores can be destroyed. I start the career for the third time since twice the automatic Score could not be had landed and the program aborted. Another time was reset to a previous state two previous races.
These are all indications that the game was developed under great time pressure and is both technically and content immature. Totaly outweigh the negative impressions easily and the physics would not have been good so improved, I would probably change again.
