FOV is set to 90 by default (good for 4:3) and should be manually set to 100.4 for 16:10 and about 106.3 for 16:9.
Since patch v1.1 FOV can be changed with a slider in the Video/Advanced menu.
However, FOV in this game seems to be capped intentionally to 100. The only solution i have found to bypass this limit is a mutator called "FreeFov", which allows field of view adjustments of 70-130º which is more than enough for 16:9. FreeFov can be found below:
To get the correct FOV with decimals the file has to be edited, the console command won't recognize decimals. (at least for me) So:
Once FreeFov is installed, you have to edit the file UTMutator_FreeFOV.ini in C:\Users\(yourusername)\Documents\My Games\Unreal Tournament 3\UTGame\Config\
For 19:9 last line should be edited to:
Code:
DefaultFOV=106.270273
and for 16:10:
Code:
DefaultFOV=100.394872
Gameplay:
Hor+ for 16:10.
Hor+/Vert- for 16:9.
