limiting the framerate isn´t an Nvidia exclusive feature afaik?
Its been a consistent enough fix for ME for said issue.
I´ve had crashes since, but I think I only had the GPU crash again when I turned off frame limiting again, just to see if the problem might have gone away with a new build.
DX11 is NOT a “workaround”, without Nanite I simply wouldn´t use Unreal, as we would not be able to do what we need to do for our style of projects (linear content creation, not game dev).
