Hi Fangqin,

This is case where "A picture is worth a thousand words", so could you
post a picture of the scene with the buildings far away to illustrate
the issue.  It could be lack mip-mapping or could be a driver bug, it
could just the LOD settings on your database are inappropriate... in
short it could be many things, but without a screenshot we can't
really say what it might be.

Robert.
