Hi performers,

I have a question regarding texture formats. For performance reason I
would like to use the 5551 texture format combined with mipmap generation.
I use the pficonv utility like with format 10 (PFTEX_UNSIGNED_SHORT_5_5_5_1)

    pficonv -f 10 -m tex.rgb tex.pfi

But the result is a greyscale texturing. What's wrong ?
If I use format 3(PFTEX_UNSIGNED_SHORT), it works fine without mipmap
switch.

   pficonv -f 3 tex.rgb tex.pfi

But using the mipmap switch I get bad flickering in the far distance mipmap area.

  pficonv -f 3 -m tex.rgb tex.pfi

Has anybody some experience with the 5551 format ?
Many thanks
