Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta Uses integrated GPU instead of dedicated GT750M

It seems there is some problem with Nvidia drivers or with the game engine itself, the problem is that game uses Intel HD graphics instead of the dedicated GT750M. Tried forcing GT750M from Nvidia Control Panel without any luck. Game runs like 20fps on medium settings, which is not good at all. Laptop is not throttling or overheating, also all powersaving options are put to high performance mode.

Laptop specs:

i5-4200U
6GB DDR3
GT750M 4GB (337.80 drivers)
250GB Samsung 840 EVO
Windows 8.1

I'm having the same problem with the full version. i7 4700 HQ, 765M, 16 GB RAM.
