Assetto Corsa Competizione has the following requirements:
- Wine (version 8 or above) is required on Linux. For this reason using AMP’s Docker feature is recommended
- The server uses configs in UTF-16 format. AMP’s File Manager cannot handle that format properly. For any required changes to a config that are not handled in AMP’s UI or otherwise by AMP, download the config via AMP’s File Manager, edit it in a UTF-16 compatible editor, and then re-upload it via AMP’s File Manager (drag and drop)
