Hello!
This is just for anyone having trouble getting the game to detect your graphics card:
When I booted up the game it detected the wrong card, and even when I went to the nvidia control panel, selecting the correct card didn't do anything. It turns out that I had to go through the windows graphics settings, locate Vintagestory.exe and set the GPU from there (type graphics settings in the search bar [I had to do this for another as well so if you run into the problem down the line with something else, try it out]).
Hope that helps anyone having the same problem!
(about to try the game for the first time, wish me luck!)
