Finally managed to get onto nKP this evening, albeit only for about half an hour.
First impressions quite good. the car 'felt' a bit weird, but it's getting better as I turn the suspension, aerodynamics and brakes to my liking. Slides are much more catchable and predictable, but I still think the Ftarget actually has a bit too little grip, especially at the rear, and a little too much bias in the aero towards understeer... but again this is probably largely due to setup.
The FFB is a lot better.
Still annoyed that Kunos, despite working with F3 teams (apparently) can't manage to get the setups much like an F3 car (particularly the monoshock, preload and droop limiters), as that is, in my opinion, super critical in simulating a post 1994 F3 car.
Can't comment on the other cars yet, as I didn't try them.
But it certainly seems like progress!!!!
