MasterZoen: It's now Aug. 2015, and I've just encountered this problem. I'm running an i5-4690K that has integrated graphics with a Nvidia GTX 970 card, and unfortunately there is no such drop down in the driver control panel for the game. I don't know if modern drivers removed the option, or if my 970 just doesn't allow it.
drealmer7: Hmmm, I wonder if there is an issue with the 970 perhaps? I wonder if anyone else with one can try Arcanum to see if they have issues. I have a GTX 550ti and have never had any problems with Arcanum on my win7-64bit, just for informaiton.
It's very possible that the new architecture has problems with old video coding. I can't get NOX to run properly at all, just shows a black screen with what looks like 3 1x2 inch boxes in the upper left corner that seem to be the same image of repeating garbled lines when it doesn't outright crash my system.
I remember these issues being pretty common 10 years ago, but then DOSBox solved most of them.
Edit 4/19/2016: I finally got Nox to work, I had to download the installer from GoG.com, install the game, and then enable compatibility mode for Win 98/ME. For some reason the game version that Galaxy installed just would not work.
In addiition, Galaxy no longer works for me at all, so I've downloaded all my games again with the GoG downloader and reinstalled them.
