KF2 Black Screen With Sound: the -dx10 Launch Option Fix
If Killing Floor 2 launches, the menu music or in-game sound plays, but the window stays black, one early community workaround is to force DirectX 10 through a Steam launch option. This is a short fix from the early days of the game, and it comes with a visible trade-off.
Warning first
The author states that this method disables animations. Expect no running, jumping and similar character animations while the option is active. Treat it as a way to get the game running, not as a permanent setting.
Steps
- In your Steam library, right-click Killing Floor 2.
- Choose Properties.
- Click "Set Launch Options...".
- Type
-dx10. - Press OK.
- Press Close.
- Launch Killing Floor 2.
To undo it, open the same field again and clear the text.

FAQ
- What does -dx10 do for the black screen?
- It forces Killing Floor 2 to start in DirectX 10 mode, which gets around the black screen on some setups where the game runs and plays sound but shows no picture.
- Are there downsides to running with -dx10?
- Yes. The original guide warns that this mode disables animations, so there are no running, jumping and similar animations.
