There's no graphical config file and even at 1920 the game looks... less crisp than I remember it being even years ago. Or at least the lobby is less crisp. Any way to force it to higher quality?
Maybe you can change some options in the driver of your graphics card to make the game look better.
Also make sure your screen ratio is set correct.
I am not sure what exactly you are referring to.
The graphics haven't changed since 6-8 years other than the new gui. If you post a screenshot of an example, we can find where the problem may be.
