Now I do run in WINDOW mode and the screens are not dark anymore at all.
It is not compulsory to run in "fullscreen" mode just to have the night
I have reverse my changes above for location and only havee done the below:
It seems that the DirectX engine look at the graphics card settings primarily.
I do got enough lighting for both window and fullscreen mode:
full_screen = 0 (In Options file - window mode)
HD Graphics Card settings changed to:
==============================
Brightness 48 / 100
Contrast 50 / 100
Hue 360 /360
Saturation 14 / 100
For window mode set the resolution X and Y smaller than your actual display X and Y settings.
start.ini file in \Programs" folder
screen_x = 1280
screen_y = 1024
The settings in "options" file in "\Programs" folder for brightness, contrast, gamma only do apply the settings in the game when in fullscreen mode:
"options" file in \Programs" folder
video.contrast=1.0000000 (middle)
video.gamma=1.0000000 (middle)
video.brightness=0.0000000 (middle)
