Compatibility/stability if SONAR X1 (not X2) on Windows 8?

I know there are blogs written about how SONAR X1 works fine and stuff on Windows 8, but there is always a discretion note stating that it is not officially supported on Windows 8 etc.

I will not be upgrading to X2, but will be upgrading to Windows 8. So I was wondering if anyone out there has been running X1 on the release preview of Windows 8 and have come across any compatibility problems? Any input on performance is welcome, but I'm more concerned about actually compatibility and stability. Thanks on advance
