Issue Description:
Nvidia Optimus (used in gaming laptops to pick between the integrated GPU vs Dedicated GPU) is not being triggered to select the Nvidia card in the launcher. It seemed to work in the beta. This causes the launcher to detect an integrated intel as the video card. While I can work around this by disabling the optimus GPU autodetect, it is annoying.

Manually adding the darktide to optimus list didn’t do anything, I guess cause the launcher is a different app.

Steps to Reproduce:

  1. Launch Darktide
  2. Click Setting
  3. Click Reset (to get the default video settings for the hardware)

Follow up:

Adding the Launcher exe to the explicit list does make it trigger the GPU so the auto settings will pick up the card. The user will have go in and do that manually.
