You’re right in the sense that it’s a game or “Sim” that is trying to create the illusion of real life.
The gap between real life and the game IS the learning curve.
Getting your settings right for your wheel is a huge part of that curve and it is quite subjective hence the massive difference in opinions evident here and elsewhere.
This is why knowledge of the settings and how steering is simulated in a game and a FFB wheel is the only way, you can’t shortcut it.
If you do push through this and get something that feels right for you, then you pretty much have something that replicates the real thing well enough that you have no problem jumping between it and real life.
I even learnt left foot braking on a sim rig before bringing it to the real world.
So it’s wrong to say it’s garbage and not anything like driving a real car
There is a gap, but once you adjust to that gap, you can learn a lot about the real thing.
My history saw me getting Gran Turismo (the first one) on recommendation of my track day instructor in 1999 so I could get a better handle on my R33 Skyline GTS25t.
I played through Gran Turismos and Forzas on controller until I got a wheel for Forza 6. And they was awful with a wheel.
I pushed through that, got PC, AC, Dirt Rally, Horizon 3, spending month after month learning.
Now I am very happy with what I experienced with a wheel.
I understand the limitations of my wheel (G920), it doesn’t have a huge amount of torque so it cannot replicate real world forces. But man I tell you in the right game with right settings it takes me right back to drifting my R33 all those years ago.
There are wheels out there that are much closer to the real thing though.
Most consumer grade wheels cannot come close. Low torque, belt driven wheels with spring loaded potentiometer brakes. It’s going to feel off compared to a hydraulically assisted brake or steering wheel rack right?
But you can get something that is more immersive and more natural than a controller.
