Amd HD 7700 Driver?

I have a question apparently there are no official drivers for the HD 7700

not the Hd7770 but already the hd7700 why is that so and where can I get the official? And how is fortnite going on

Just download the auto detection program from AMD. This detects which driver is needed. https://www.amd.com/...000-series

If Fortnite on it runs I would rather deny. Since the map is about 7 years old and Epic for Fortnite requires at least a HD 7870.
