If you have an monitor with a native res that is higher than the res at which you want to run the game (e.g. 1680x1050) and you run the game at lower resolutions e.g. 720p, it will look poor due to the monitor doing all kinds of crazy scaling.
You should try running the game in a window. If you want full screen, then you should set the game's resolution in config/option to be the same resolution as your display.
To force a resolution not shown in the config/option screen see the KB10 article.
