black screen and only audio, help!

[6x6]

When I start the game the screen becomes black and I can hear only the audio
games like bf4 or ac4 are actually working on my pc, so I don't think the problem is the video card.
help me please!

try run NS2 as Admin and/or re-validate your NS2 data via steam... and/or if u ve Adobe Creative Cloud installed, disable it.

Also worth noting, a similar symptom can be cuased by having an improper value in
Steam\userdata\<steamid>\4920\remote\options.xml
If you delete the line:
<marineVariant>6</marineVariant> things might be nice

thanks everybody, but I found the solution by myself.. I just pressed Alt+Enter while playing, so the game went windowed and I changed the graphic options.
