Video card supports DX11, game reports hardware directX level of 8.0 (software 9.0)
Radeon HD 7870. Getting this issue with Portal. Anyone have any idea how to fix this so it uses 9.0c in like the card supports? Because of this certain graphics settings are disabled.

Add "-dxlevel 90" to launch options to force it into Directx 9. Then after you launched the game once with it, take it out or else your in-game video options will keep defaulting and never save.

When ever I force -dxlevel 90 it just crashes I'm using the same card as him. I think the steam pipe update broke everything because everyone in the portal 2 hub is having the same issue.
