I wonder if fgl_glxgears is still usefull, as we don't have an own
libGL anymore, however, could you show glxinfo?

glxgears is not a benchmark, but it should give similiar results when
run with the same driver on the same hardware, so we fail here?
Could you try some "real" benchmark? Like playing Quake and look there
at the FPS counter?

I really would love to know what difference is in that binary.
However, it seems we do something wrong, maybe Romain has time to look
at that.
