Bug ID: 43330
           Summary: Multiple games need nvapi function 0x6a16d3a0
           Product: Wine-staging
           Version: 2.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

      Distribution: ---

Watch_Dogs(1) and CoD Black Ops 2 need this function
fixme:nvapi:unimplemented_stub function 0x6a16d3a0 is unimplemented!

Watch_Dogs will complain about a missing DX11 adapter and BO2 fails silently.
Workaround is simulating an AMD card:
[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"VideoPciDeviceID"=dword:000067df
"VideoPciVendorID"=dword:00001002

Since BO2 renders close to perfect in Wine-2.12-staging, this function should
get some attention.

(I tagged this as wine-staging specific issue, because only in wine-staging
progress is done on nvapi)
