I’ve saw this type of issue before with DX12 and it did not happen with 11. Sometimes that’s due to the projects having so much content that it overloads the system. But, the GPU crashed/device removed I’ve saw happen from a LOT of variables. We’ll have to play process of elimination to try to figure out the area. Have you tried going into NVidia control panel and resetting everything to global default and testing? (Also when removing config folder remove any other folder there other than ‘Content’ for testing) Have you installed any new components? (Specifically new RAM, Motherboard, or CPU as hardware compatibility is common culprit too)
