I recently got the game I mentioned in the title. I love it so far, but it has become unbearably slow. I have to mostly play it on PC at this point. Whenever I start a new character, I can't even leave the starting map (it goes colorfully pixelated and doesn't respond). For some perspective, I also have Pillars of Eternity, Tyranny, Shadowrun Returns, Planescape: Torment, among others, and they are able to run rather well. Is there a fix to this? Any kind of tweaking I can do? I've disabled vsync and turn the anti-aliasing down to low, but not much has changed. I have a mid 2010 Macbook with macOS Sierra.
