I have a monitor that supports that resolution and after I installed the game a month ago, it was working great, and it defaulted to that resolution, which was awesome.
I had to use another (smaller monitor for a while) and I decreased the resolution, but now that I got my big monitor back, I can't get it to run 1920x1080 again. I just don't see it on the list of video options. Tried to edit the config file, did nothing. Any special tricks anyone know to get this working?
