If you are having a problem with your graphics card or a particular game...Please report it to AMD. Keep in mind that the more reports sent to the Catalyst engineers, the more attention paid. This is the only way things get fixed. Note that all issues must be reproducible (this is why specific information is required), and submitting a "Issue Report" is not a invitation to a dialog with AMD. Don't expect a reply. Just report it and encourage others to do the same.
We'd like to help, but you have not provided much information about your system or OS used.
That said, the games you are playing are not demanding, so if your system works best with those particular drivers, i would recommend to keep using those.
