For a fact, the triggers' range of motion have been shortened for the Xbox One. That's one contributing factor. It may have been shortened for the analog sticks as well. Contributing factor # 2.
Try playing around with the deadzones.
I used to have the same problem in FM4.. brakes jamming up, tail suddenly stepping out.
Here's what I did:
- Increased the max range for steering, throttle and braking to 100%
- Set deadzone for all three at *zero*.
- These settings make the controls more sensitive to your inputs, and you're essentially looking at a wider range of motion for all 3 inputs. What this means to you the driver, is that you have more control over your car by making intricate adjustments.
This should help, cheers!
If it doesn't, you can always go back to FM4!
