Resolution:
I edited "resolution" and "aspect" config\graphics.cfg like this.
Simulation
{
resolution = {1280, 768};
bpp = 32;
fullscreen = 1;
aspect = 1.666666667;
}
FOV:
C:\Program Files\Ubisoft\Eagle Dynamics\Lock On\Config\View
Change "120.0" to "145.0"
-- Camera view angle limits {view angle min, view angle max}.
CameraViewAngleLimits = {}
CameraViewAngleLimits[PlaneIndex.iSu_27] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iSu_33] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iSu_25] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iSu_39] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iMiG_29] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iMiG_29K] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iA_10] = {20.0, 120.0}
CameraViewAngleLimits[PlaneIndex.iF_15] = {20.0, 120.0}
Note: Su-25t FOV is unchageable AFAIK
