Wrong video card use on Asus Zephyrus. Likely the AMD one and not the Nvidia

[guysoft]

Description
I have a laptop that comes with an integrated GPU chip by AMD and main GPU for VR which is Nvidia RTX.
The issue is that firefox is trying to send info to the Integrated AMD GPU and not the nvidia one where the VR is connecting.

To Reproduce
Steps to reproduce the behavior:

1. Using an Asus G14, that has an AMD integrated GPU and Nvidia GPU
   Connect the VR as needed using the Displayport via USB.
2. Launch Steam VE and open the developer web console to follow errors
3. Start Mozilla hubs on this link: https://hubs.mozilla.com/
4. See error "Wrong graphics card"on Steam VR

Expected behavior
Firefox should send the GPU data to the Main GPU for VR

Hardware

• Device:Asus Zephyrus G14 with HTC Vive
• OS: Windows 10
• Browser Firefox, 82.0.3

Additional context
Workaround is to plug the VR using the HDMI port that is soldered to the AMD GPU. That makes hubs load, but its slow and laggy because this is an ingratiated chip and not the GPU that is built to be VR Ready.

Basically if you want VR to work on this laptop it needs to be on the Nvidia GPU and not the AMD which is integrated

Also other VR games seem to use the right GPU.

This doesn't sound like a Hubs-specific bug, but something related to how Firefox and the graphics drivers are interacting. This Bugzilla ticket seems to indicate a history of multi-GPU setups having issues. However, the most recent comment suggests that the following workaround may also work. Have you manually set the graphics card that you want an application to use in Windows 10 by going to 'Graphics Settings' and setting the browser to use your high performance GPU instead of the default / integrated card?
