DirectX 9 Error
When I open Portal it starts in DirectX 8. I don't understand why. But on top of that, when I type "mat_dxlevel 90" or above 90 it shows up with the pink and black checkers screen. Please help!

Try "-dxlevel 90" in the launch options to force it to default to Directx 9, then take it out on the next load or else your settings won't ever save.

That worked, thanks.
