Even though you're seeing all worlds affected, please try the suggestions in the thread, first in the accepted solution and then in the other posts.
If nothing works, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
