This is not necessarily Content Manager issue;
I often run Assetto Corsa without Content Manager.
- AccuForce wheel base has a separate controller
with fan noisy enough to discourage leaving it powered on...
- If/when accidently launching Assetto Corsa without first powering on Accuforce,
then (after powering it) Assetto Corsa will use it in settings, but not driving,
until after deleting Documents\Assetto Corsa\cfg\controls.ini
