Question: Does the log always report hiding GPU vendor ID: 0x1002 and device ID: 0x73df?

I'm working out performance issues with Fallout 4 (dxgi 3.0.1, Nvidia GeForce 6.10.88) and I see this in the log:

info:  Found device: NVIDIA GeForce RTX 5090 (NVIDIA 610.88.0)
info:  DXGI: Hiding actual GPU, reporting:
info:    vendor ID: 0x1002
info:    device ID: 0x73df

I see the same message including the vendor and device in some of the logs users have posted here so I was wondering about the significance. DXGI is still detecting the correct feature set and capabilities isn't it?

I haven't configured hideIntegratedGraphics or dxgi.hideNvidiaGpu and used dxvk.deviceFilter = "NVIDIA GeForce RTX 5090" specifically.

On Windows Nvidia is always hidden by default through dxgi since dxvk-nvapi isn't present and so dxvk might cause issues (like crash) in games that interact with Nvapi.
You might miss out on some Nvidia specific features in games, but otherwise it shouldn't cause trouble in general.

What Blisto said; you can try setting dxgi.hideNvidiaGpu=False but it's unlikely to do anything for FO4 performance.

Ok, thanks @Blisto91 and @doitsujin!

That answers my question.
