hm, i dont think there is such an option. you can change the arc wich is probably what you mean.
i tested a bit further with the following setup (camera 1000 quants directly above the player entity) and found out the following:
1) in windowed mode: to achieve the same vertical view in 1280x800 like it is in 1024x768 i have to set the camera to 1197 quants above the players head. the camera.arc value is 60 and camera.aspect is unchanged! i just set the camera higher and i have a wider view horizontal but the same distance vertical !
2) in fullscreen: i have to change the camera.aspect to 1.2 ! and set the camera to 1197 quants to achieve the same result i have with 1024x768, 1000quants above the player with camera.aspect = 1 !
i don't know yet why this setup works, but you can clearly see that you can see more of the scene to the left and right but the same up and down. i measured screenshots to find out the correct distance and .aspect values...
here is the original screenshot 1024x760, camera.arc = 60, camera.aspect = 1, camera.z = 1000, fullscreen

http://www.ackbytes.com/upload/1280a1_2.jpgi really have NO IDEA why you have to set the aspect to 1.2 in fullscreen but not in window mode. however i understand why you have to pull the camera 197 quants up, thats just to get more view of the same scene.
maybe its an engine bug? can anyone test this please?
