I Think maybe you're looking for a "Bloom" Post Processing effect. I'm not sure if some video cards can attain a mod that forcefully uses it, but i've been looking for such an effect to go into games such as FFXI.
If anyone knows how this can be done, please let me know.
But also Delson, you'll want to make sure you get the most out of the background texturing detail by raising your background resolution, higher than the normal game resolution. Not only will it give you better texturing detail, but also give you an anti-aliasing effect.
