I did a GT3 race on the Nurb Combined circuit for the first time in PC2 last night, and it felt wierd as hell.
It was online, 2 lap race, I think there was 6 of us in the lobby.
I was using the NISMO GTR, with my universal base tune applied, raised the ride hight 2mm, and went with a longer final drive gear. Downforce set at 1 in the front, 4 in the rear. Normally, on most tracks, the car feels decent, but not perfect, with instability at low speed, and some understeer at high speed.
However, in the quali session before the race, and in the race itself, the car felt absolutely GLUED to the track, like I've never felt a car in any PCARS game before. It was on rails!! And not in a way that I felt like it was because I was driving out of my skin...it literally felt like the car was on rails.
The section I noticed it the most was after the Carrousel, through the really twisty bit. I don't know how else to describe it other than it felt like the car was 1/2 on auto pilot. I felt like I was missing braking points, carrying too much speed, but at the same time, was hitting every apex. I also got a confidence from the back end like I've never felt, like it was impossible to spin.
The visual seemed to get a bit screwy too. I was mostly concentrated on the car just in front of me, but through the twisty section, it seemed as though the frame rate dropped or something. This is when I really felt like the car was doing something different to my inputs, but maintained really good pace.
Thinking about it now, it felt like playing a driving game with all the steering, throttle, and brake assists turned on. It's been years since I've tried any of those, but that's what it felt like - just mash the gas and go.
