  We present an overview of recent results from the CP-PACS computer on the
quenched light hadron spectrum and an on-going two-flavour full QCD study. We
find that our quenched hadron mass results are compatible with the mass
formulae predicted by quenched chiral perturbation theory, which we adopt in
our final analysis. Quenched hadron masses in the continuum limit show
unambiguous and systematic deviations from experiment. For our two-flavour full
QCD simulation we present preliminary results on the light hadron spectrum,
quark masses and the static potential. The question of dynamical sea quark
effects in these quantities is discussed.
