Talk:DirectX Versions

Is it possible to force the game to run at a particular DirectX level? I've got a DX9 card and I'd like to see what things look like at lower rendering qualities... --Cargo Cult 10:26, 7 Jul 2005 (PDT)

I found some excellent example pictures for comparisons between versions in HL2, but I don't know if we're allowed to use them directly. (Maybe just link?) Here's another page with a list of technical version differences. --AndrewNeo 10:45, 7 Jul 2005 (PDT)
