i badly expressed my point, i was asking how does other games work:
i already know that all the RTS games just increase the viewable area, but many 3dgames doesn't change the fov, you just see the same things, but more detailed, sharper.
Textures have nothing to do with this, what change is just the amount of pixels used for the same scene, to see the difference just take two screenshot with different resolutions from the same position in a 3dgame, and substract one screen to the other with a good photoeditor....
Many of these games have their own interface, that can be simple (like firstperson shooters) or complex (spacesims), i'd just like to know how they work: i can hardly believe that they have created dozens of versions for the same interface for any possible resolution, so i thought it was just scaled from the nearest resolution version of interface, if there are more versions, and if it is possible to do so i think fs2 could benefit -alot- from this.
