some change fixed the slow down issue in nexus ,but now there something different wrong with nexus area and bit of other stuff that is missing image or something with plugin causing it to go black screen . you can still move around it just drop you into a resolution propty undefine error afterwards. yet you can keep playing from where you left off the error dosent soft lock you since appears little after auto save. it just forces you close out the game and start it up again but the problem also is with how you come back to the nexus
