It looks like this out of the box.

I managed to fix this in the past, I believe, but it was painful. The TL;DR is that you need to add NSHighResolutionCapable to the info.plist for each AIWar .app component and setting the real display resolution in the game settings (it's *just* readable enough to do so if you know where the setting is already)

It would be nice if this was done for us by the dev while packaging the app bundles...
