I can go up to 1280 x 1024 resolution mode, there appears to be one more option on the slider, when selected the game crashes to desktop.
You have to delete the cfg file and start over and tweak the settings from there.
Does anybody know if a widescreen patch or -resolution mode option ???
I checked over at Widescreen Gaming but they have only Tropico 3 listed.
