You need to explain what it is you're trying to achieve.

Assuming you're using a scale of 1 unit = 1 metre, you're asking for millimetre precision over one hundred kilometres. Which is impossible given the number of bits in the depth buffer.

Try 0.1 to 1000.0, which is really pushing it, but may be acceptable in some cases.

Basically, you need to reduce the number of zeros after the decimal point for the near value, and the number of zeros after the decimal point for the far. It's the ratio between the two that counts: you're asking for a ration of 1:100000000 which can't be expressed in a 24 bit depth buffer.

EDIT - having read you're post again, what are the furthest depth values you need? Maybe try 0.001 near to 1.0 far.
