DiRT Showdown is an arcade style destruction derby racing game. The multi-monitor support is good, resolution options are listed in game however the FoV appears to be an odd mix of horizontal plus and vertical minus, this appear to differer from system to system, for example mine is almost right however I've seen screenshots that are nearly completely vertical minus. The UI is centred but the HUD, at least on my system, is not. As for the video itself, I've tried to do another commentary while playing the game, I'm still not very good at it so please bare with me, also please like or dislike my video and comment.

While this video can be watched on any screen it has been encoded to look best on a multi-monitor system, so if your running such a system, then select original quality from the drop down box and watch in fullscreen.
Copy paste of video description:
Dirt Showdown on the PC, Original resolution was 5040x1050 aspect ratio of (48:10). If you are running a resolution with a width higher then 1920 (30'' monitor or multi monitor) set quality to original and view in fullscreen.
Dirt Showdown runs natively on a multi-monitor system, however I personally found I had to load the game in windows mode then swap back to fullscreen mode, in order to get a decent frame rate.
