Hey you can play this game at any resolution & aspect ratio using nGlide from zeus-software. Once installed you can find the nGlideConfigurator in system32 and force any resolution for 3dfx games. For it to work you have to start earth 2150 setup.exe and select glide0 as the graphic API.
You can also set things like framerate, cursor size, etc via console commands like those:
Use any values you want. Type the commands in the game chat using ENTER. All values set in the console will be reset upon leaving the game unless you put those settings in an autoexec.con file at the root of the game.
PS: Thoses are the only commands I know besides cheat commands. Feel free to post additional commands here
