Many thanks for the workaround for Falcon, i took the takeoff training TE as a wingman test run and i think i played my part ok
I quickly loaded in the latest drivers from Nvidia 44.03 but alas Falcon ctd on mission loadup so not sure if its the new drivers or a combination of workaround aswell? anyway i went back to the drivers 41.09 again and all fine again. I had put Lock on out of my mind for a month now but this has triggered my anticipation again bigtime.
