In FSX I still se my graphics card as HD 4800 even if I now have a HD 5870. It is OK in device manager, listed as HD 5800 Series. In other programs and tools I see HD 4800.
So I searched the registry after a total ATI driver
removal/cleanup and reinstall of the Catalyst 9.11 64bit edition. Still there are a few HD 4800 registry edits that I am not allowed to delete, even if I am administrator and have UAC OFF.
I hope someone can tell me how to get rid of those registry keys if possible.
