i just started the x1 challenge and i have to say im enjoying something difficult for once!
definitely possible with the controller... requires insane amounts of concentration, but possible!
It is possible to get bronze on this challenge with the DS3 controller. I managed to get at least bronze on all 3 and I managed to claw a Silver on Monza, but I think for the other tracks, its almost impossible to do unless you have a wheel.
Doing the challenge with the controller is possible, just requires ALOT of practise and trial and error
I'm debating setting TCS to 1 and turning on skid recovery.
A bit unfair that the gold times are impossible to beat with controller.
