I had a problem with my resolution being 800x600 and it couldnt be changed so I dig in it.

If anyone has this problem go to: Documents > My Games > Exodus > Default Now open display.cfg file and edit int32 u_width & int32 u_height

Hope I helped someone! (Also I saw that another post with this res bug but putting the game in vista compability mode didnt worked for me :P)
