NVIDIA GT GeForce 750M 2GB, Late 2013 MBP. After updating to High Sierra, the system freezes, kernel panics and UI is slower than a base MacBook when plugged into my 4K monitor. It's completely fine w/o the external display using Intel's built in GPU.
Here's my memory use with iStat Menus Open w/o any open applications:

NVIDIA has released 3 GPU updates since I upgrade to High Sierra and all have made the issue slightly better but none have fixed it. Every guide on how to remove NVIDIA's custom CUDA drivers don't work in High Sierra. I go to the folders identified in NVIDIA's own documentation and there is no sign of the drivers there to delete. Anyone dealing with this and have any advice? I was waiting to post for the first HS update and now that it's out, my issues persists. I've been gettin work done w/o an external monitor which has really slowed down my productivity.
