Jokes aside, the cars have too much understeer, even after the 1.05 patch got released the cars are still too slow compared to real life performances.
2019 cars are way faster than 2018, but unfortunately this is not the case in the game.
Imo, the ingame cars of F1 2019 have...
...too much drag. We need to crank the aero up pretty high, which is a necessity to get close to the real life highspeed cornering speeds, but in contrary the cars do not get to topspeed as fast as irl which makes all the time gained in the corners getting lost on the straights. To specify, take France as an example, right before the start finish line Hamilton reached 8th gear at a speed of around 300kmh, whilst taking the long right hander corner of Turn 11 i believe at Sector 3 at around 205 kmh, if i try to get close to that ridiculous cornering speed by adjusting wings to a higher configuration (i use 11 / 9 wing at France to get close to the crazy real life cornering speeds) i only reach 8th gear and 300kmh on the start finish straight at the green Rolex clock which is located at the end of the pitlane. Unrealistic.
...too much understeer. At tracks that are supposed to have medium to low aero settings, the cars tend to have too much understeer to turn in and are also too prone to midcorner understeer in low speeds as well, whereas irl the cars are driving on rails during these type of corners. This unfortunately forces us to either use unrealistic suspension and roll bar settings or maximizing aero to get some better grip. Unrealistic.
...not enough highspeed grip. This is connected to all above.
How can we fix this?
Basically the cars themselves need to get at least another 1 - 1,5 seconds faster to what they are capable of doing right now, by...
...increasing high and medium cornering speed grip, for medium and higher aero settings and therefore reducing understeer.
...reducing drag for higher aero settings and thus making acceleration become faster.
...making the current aero grip levels of 11 / 11 wings available for 6 / 6 wings or 7 / 7 wings instead, so that the cornering speeds we currently are able to take at 11 / 11 wings should become valid at medium wing setups, increasing overall grip and cornering speeds.
Also, please for Gods sake, fix the car setups already.
At the moment people use completely unrealistic setups, using low aero configurations most of the time to maximize topspeed and acceleration as going for high aero makes little sense right now due to the insane amount of drag, these people also use some pretty shady suspension / anti roll bar settings that in reality would destroy the tyres pretty fast.
Meanwhile in real life, topspeeds are slow, drag is minimal, acceleration is ultra fast, and cornering speeds are crazy high.
Car setups could be fixed by...
...making too soft suspensions increase understeer, whereas a stiffer setup should do the opposite.
...making too stiff anti roll bars increase understeer, whereas a softer setup should do the opposite.
...making positive camber increase understeer, whereas a negative configuration should do the opposite.
...making Toe in increase understeer and help stability on the straights at the expense of cornering, whereas as Toe out configuration should do the opposite.
...making medium to higher aero settings more viable to use instead of going for low setups.
All in all Codemasters have lots to do to fix this game, the cars performances and car setups are important and need to be fixed ASAP, currently the game is nowhere near to a perfect "official" representation of the sports.
Seriously, do something.
Hope it will get fixed before the end of this season.
