The one track from an older game I'd love to see is Complex String.
I would love to take the RGT 4.2 on that track for hours.
Big fan of the G923 here . . . but the haptic feedback from my rig is so great for tracking rear wheel stuff. I'm afraid I rely on it too much now.
Such a huge improvement . . ! If my wheels are off the ground, or my tires no longer have grip, the steering should feel lighter. Hopefully this new physics model will continue to do that.
I second the first bolded thing above. And I provide a hearty "AMEN" to the second. However, as you pointed out, the engine thing wouldn't be part of a physics update.
Some of the initial setup can take time but once you get the hang of it, you can be good to go.
After the physics update, see how your car handles. After you have it dialed in, then start to assemble your custom race. I have a couple cars that right now are at 592 & 594 PP (SH tires each) and I race against 620-660PP cars. Tire wear and especially fuel are where the race is won/lost.
And then there's Sophy.
Perhaps when the update hits, we can get 1, 2 or 3 lap races against Sophy (fingers crossed!)
