The best way I can describe my overall dissatisfaction with the new physics is the way in which the whole car now feels glued to the road. With the old physics I could feel every wheel as four separate contact points between rubber and track surface. It made the driving feel so nuanced. Not anymore. Now the entire underbody of the car feels glued to the road, and I’m not sensing different loads between the four wheels.
Moreover, the transition from grip to sliding has become more sudden and unpredictable. This was a big complaint back when the game first got released. Later on they improved it, but now the problem has returned. The issue is especially prominent in cars like the BMW M2. This car always had an urge to bite, but it was manageable enough. With the new physics it just feels too sudden and weird.
I feel like I'm in the Twilight Zone, looking at all the posts complaining about the new physics. I keep thinking, "Are we playing the same game?" From my point of view, most everything is better. From feedback (through the wheel), to better weight distribution/transfer, to more realistic braking (i.e LESS on rails, not more on rails, as some have said).
Maybe it’s different input devices that make us wonder if we’re playing the same game. Or different choices in go-to tires? I’m not using a wheel and I spend most of my time in road cars on sports tires. I largely disagree with the things you’re pointing out there.
Feedback through the controller seems slightly worse to me. Maybe it’s a placebo because the physics are so different.
Weight distribution is a doubled-edged sword for me. Modern MR cars have become more stable during off-throttle cornering, which seems more believable than before. However, left/right weight distribution during cornering feels dull with the new physics. Maybe it’s because of the grippier tires.
Braking is still flawed. Cars can lose balance too easily and this has been an issue since day one. For some reason people have pointed it out as a new issue, but it’s not. That said, cars have become more resistant to changing direction under hard braking, which I suppose is more realistic.
The only thing that seems vastly improved to me is how cars now get unsettled when you hit taller curbs hard at an odd angle. You didn’t mention that.
