I found a working solution to this…
Turns out, there are two different control panels that will pick what GPU to use:
- NVidia Control Panel
- Windows Graphics Settings
To select integrated GPU for Brave:
- Run “Settings”
- Type in “Graphics Settings”
- There will be an application list, click Browse…
- Select Brave’s EXE file (usually “C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe”)
- Click on the entry
- Click Options button
- Select “Power Saving” (for the integrated GPU), click Save
Now Brave will use the correct GPU.
