I don't have a problem. If you pan the screen around, is the humming consistent, or are there locations where it is better or worse than others?

Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the D:OS support tool (for the PC version). The report will contain system and game information, any crash dumps, and your saved games (which are probably not relevant, so if file size is an issue most can be deleted from the zip).
