Wow! This is strange - I have this piece of code in a predraw
call back and when I use it to disable AA my draw process takes
10 times longer (or more) than usual. Any ideas? I'm running on RE2
w/ Performer 1.2++

   ....

  long mask = 0;
  // Collect override bits in mask
  if(over->aa != -1) {
    pfAntialias((over->aa)?PFAA_ON:PFAA_OFF);
    mask |= PFSTATE_ANTIALIAS;
  }
        ....
   
  pfOverride(mask, PF_ON);

  return PFTRAV_CONT;
}

Any ideas? I'm stumped.
