Symptoms

Opening up No Man's Sky, SteamVR pops up an error that says wrong video card please plug your headset into the same graphics card as your primary monitor.

SteamVR stays stuck showing "up next" with the No Man's Sky logo in their waiting room, and No Man's Sky starts working on is own screen (with a view per eye) but never goes to the headset.

Note that this does not happen for any other VR app on my computer.

Yes, it was tied to a recent Windows update that added a Virtual Display Adapter for legacy Win32 apps. You need to go into Device Manager, show hidden devices, and disable that virtual adapter. Then everything should work normally.

Background and what happened

After much searching my AMD graphics card with a WMR Samsung Odyssey+ VR set still did not want to play nice with No Man's Sky.

I only have one graphics card installed (besides the mother boards integrated graphics): AMD Radeon 5700.

I uninstalled any Nvidia drivers.

Finally after reading the post above, I...

1. Opened device manager as admin
2. Showed hiddened devices
3. Looked under Display Adapters
4. Found a grayed out Virtual Display Adapter
5. A disable option wasn't avaliable, but uninstall, so I tried uninstall.
6. I think it failed the first time, so I rebooted into Safe Mode, then I did an uninstall of the device driver for Virtual Display Adapter
7. Rebooted out of safe mode
8. Had to unplug and replug-in my VR headset on the first start of the WMR portal
9. Turned on No Man's Sky and it all worked!

Note for Nvidia people
