KF2 Black Screen or Music Only: -nostartupmovies Launch Option

This page paraphrases a Russian-language Steam guide about the black screen where Killing Floor 2 hangs at startup or only plays background music. The author says it is often connected to a conflict between the game's intro videos and the video driver, and that a single launch option fixes it for most people, though it is not guaranteed.

Author's notes

The method helped many of the author's friends; if it does not help you, the author did not study other solutions.
They ran extra stress tests to simulate a long startup. On an SSD with the option, startup took about 3 minutes 30 seconds.
