Is there any way to make the ground texture more darker ? So only city lights at night flight will be seen ? Thank you ! (Im using ftx global)

Use Shade, ENB or SweetFX or even just adjust your monitor settings.

ive got shade, can you darken ground texture there ? how ??

Just lower your brightness control (black floor) on your monitor, and maybe adjust your gamma settings.

right click your desktop and select nvidea if you have it

thank you guys ! quite nice results !
