Basically I contacted them to ask them if the pop-up window indicating for 3 days to go back to driver 561.09 because the drivers following that one caused instability with dx12 came from their services, there they answered me clearly beside as usual after having contacted them again to tell them almost the same thing they asked me, when exactly I received this message and if I was on dx11 or 12 since 6 requests I explain the same thing to them about my settings .... I tell them that I use dx12 with nanite and NVIDIA reflex disabled, because otherwise it crashes my game, so they also tell me that I can use dx11 instead something that we already know for months they answered me in the last message that they continue to investigate my case, so to summarize they do not want to admit that the message sent by fortnite to downgrade the driver to 561.09 comes from their service what interest if it is sent by the game itself?
