This is unfortunately a known issue, at least in the community if not by nVidia. The current workaround is to patch an earlier known-good driver version to work on whatever release of High Sierra you're on. I'm currently running 387.10.10.10.25.106 on 10.13.3 without lag. https://github.com/Benjamin-Dobell/nvidia-update https://github.com/Benjamin-Dobell/nvidia-update
