Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems Unable to select dedicated Video Card

I am playing from a Notebook (Schenker XMG P502) with a Radeon HD 8970M. I set the Radeon settings for the game but in the game it won't let me select the Card. It only gives me the option to switch monitors, both on my Intel HD Graphics 4600.
I can't disable my onboard Video Card in my BIOS and my drivers are up to date. All other games work perfectly fine with the radeon settings.
