I'm not sure what you mean by "clearer". I always use a white background
and I have no trouble getting a very strong fog effect in ray-traced
images. I just move the rear clipping plane forward enough. I think I'm
using the default values of:

ray_trace_fog  -1
ray_trace_fog_start 0.35

Could you put a couple of images on a web page somewhere to show what
you mean?
 
Cheers,
Rob
