FGT is very easy to drive now with stock setting, as is the Caterham and the Stratos with understeer setting. With the same setting I was oversteering even on straights with the 7 and Stratos before Spec 2.0.
The tires feel so good. Street radials feel very natural and close to life, while sports hard feels like more and consistent grip is there when using cars with sufficient weight. It was a tremendous joy to drive a couple of stock cars that come with sports hard tires, like the F430, 350ZRS and S15 Spec R AERO. So much grip and control now. It was good to drive these cars stock pre 2.0, but now its great to drive them.
Racing softs do what it should have done before: when heated it melts and provide sticky, gooey grip. Racing softs are super grippy now it's fun. Driving in the rain with 100% wet tarmac on racing rain felt good, and intermediates on 27% great. Intermediates now mean something.
DS3 control feel more direct with increased feedback, with less understeer and less compensation for oversteer. One steer control and bam, neutral entry into the corner. Such a Joy.
The cars' dampers seems working better. As with real life, I set my damper compression softer than expansion, but it still seemed the suspension was on full bump at kerbs. Not anymore, the car is stiff and rolls less, but still absorbs the gap.
Online physics felt loose before, but not anymore. Perhaps because of how the tires are better? I'm not sure if online/offline physics became closer, but online feels a bit better than before.
Smarter AI. Very smarter AI compared to before. Driving Kart Jr on Autumn ring mini with advanced AI setting, set laps to 5 and it took me all 5 laps to catch up to first.
To sum it up, I LOVE THIS UPDATE. I like the physics I like the AI. New stuff that was added gets the attention, but they made the game astronomically better by improving preexisting stuff.
