I 've been trying to get realistic lighting to get on like a level...which is setup in a house backyard. adding just one directional light doesnt help at all.. What do you guys recommend?

I, as well as many others, could recommend a lot of things. It really depends what you want.

Realistic physically accurate lighting is not only very difficult, but also near enough impossible to do in real-time on current hardware.

Using the programmable pipeline (vertex and pixel shaders) is a definite must if you want realistic lighting. You can look at my summary of some models here.

Using the regular Direct3D fixed function pipeline (as you seem to indicate) really won't get you far by comparison to other screenshots you'll see around today.

It'd probably help us help you if you more specifically define what your goals are. What images/games/applications have you seen that simulate results close to what you want?

If you are looking for realism, I would even say that you won't get far period with the FFP. Sure, you can hack around with it until you get something okay, but that would be time far better spent coding your own shaders.

I would check out the Nvidia SDK. It has tons of shaders and implementations of many different lighting models. Also, if you want something more advanced, check out a spherical harmonics solution like PRT.
