Basically, there are two kind of effects you can use: Fixed function effects and shaders. The fixed function effects should run on older cards like a GeForce or your GeForce 2. However if you want to use shaders you need newer cards: For hardware vertex shader support and simple pixel shader support a GeForce 3 or higher is needed. For true pixel shader support, you would at least need a fourth generation GPU (GeForce FX).
