I think the physics of the drift improved a lot to what they were in gt6, the speed with which the wheels move is much more real, in gt6 they reacted instantaneously as soon as you played the analog, I mean they went from normal to full lock in 0.0001 seconds even in lower sensitivity. In gt6 the car felt much lighter and being so sensitive to play with a control was harder to control.
In Gt sport, from the last update, they changed the physics depending on which sheet of tune you used the car, I mean that if you put the tune of your car on the drift sheet you will have much more angle and it is almost impossible to spin off than using it on the road sheet. This seems totally bad to me since any noob can drift as it is very difficult to lose control of the car.Also having such an exaggerated angle generates slow drift which are very bad to do tandem. For me it is very unreal because you can go full lock and full throttle and do not lose control of the car what in real life is almost impossible.
The drift in gt sport requires a lot of practice but once you have it you will realize that it is much more real than in other games. For example in Forza or Asseto Corsa once the car loses grip the game is put as in a kind of drift mode, in gt sport the car behaves normally and you have to use the accelerator and direction with great caution to lose grip and control the car if you want to drift.
I leave you one of my videos, thanks for your time.
