The 737NGXu has been updated.  Do not know everything fixed but so far, the FPS have dramatically gone up.  Before I was getting single digit/digits in the teens when I enabled the landing lights and turned on lighting for the PFD.  Now the lowest I have seen is 30.  Update through Operations Center.
