The Sims 2: Failed to enumerate any DirectX 9 compatible graphics adapters.. etc

In all honesty I don't think I've ever used those. After some searching and more trial and error I finally managed to get the game to acknowledge my graphics card.

I had to manually add it into the "video cards" file in config and csconfig. I did this for the Mansion and garden stuff program files. After that, the game would load.
