Some games aren't fully playable, this may be one of them.
Edit: your video is very low end, for Rice's plugin get a Geforce 2 card (or newer), your system is too slow for a radeon with Rice's plugin (for the DirectX part, you will have too use a 3rd party app too emulate T&L with a radeon card, that's why I say your system is to slow for a radeon).
