About this mod
this mod exists to solve nasty nvida nvflex related ctd problem if your setting "weapon debris" is activated in the fo4 launcher or nvflex is set to on in your ini file. reason is nvflex is not supported for newer nvidia cards due to buggy implementation in fo4 and may raise problems, errors or ctd.

no, you are not alone with this ctd problem... ;)
it is most obvious after a new game run. even if you are fully on vanilla settings your game will ctd running to pre war vault 111. but these ctd are not limited to this scenario because they are raised by incompatible functions and erratic nvflex implementation in fo4 game code. you can turn it on in game launcher even if you own an incompatible nvidia card and will end up with ctd or other anomalies.
instead of correcting the game code the fo4 nvflex implementation is simply not officially supported anymore by newer nvidia graphics card. if you use it you do it at your own risk. the known secure solution is to "switch off" fo4 nvflex.
this mod helps you to be aware of this issue and how do switch off nvflex. if your setting "weapon debris " in the fo4 launcher is not set to "off" or unintentionally activated after a reinstallation of the game as in my case it is time to do so with any newer nvidia card.
be aware: there is no warning in the launcher if you enable this feature with incompatible hardware (at least turing cards and newer) resulting in ctd, performace loss or instabilities and even the card is compatible it may introduce some instabilities. nvidia simply do not support fo4 nvflex with their newer 20x0 rtx cards.
if you encounter ctd for no reason trying to enter the vault or after reinstallation of the game using or upgrading to a nvidia turing graphics card just open your game launcher again and deactivate "weapon debris" effect option in advanced settings tab.
watch the sticky post in my mod thread for direct access to the nvflex ini setting. you may encounter this problem also while using your weapon and fps slows down followed by ctd or freeze.
as far as i could test it seems that most or even all nvidia rtx graphic cards and newer are involved. i was affected while upgrading my pc with a rtx 2080ti and encoutered fallout 4 at vault 111 ctd even after a fresh install. i encountered the ctd always while trying to reach the pre war vault 111 even with vanilla settings.
this chosen "nvflex switch off" method solves even some more strange ctd during gampeplay introduced by fps sudden slow downs. since these experiences i do not use nvidia debris feature anymore including any workarounds.
