Bug ID: 41640
           Summary: add rx 480 into directx.c
           Product: Wine
           Version: 1.9.22
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

      Distribution: ---

There are 4 and 8Gb models. Also lots of venderos. My card is from XFX.

I was about to form a patch myself, but I wasnt so sure how to make a correct
patch.

I just tested passmark 7.0 and it had some 3d benchmark and it showed that I
have ati 5600 model or something like that. Most likely that's the backup card
when wine doesnt recognize cards right.
