Yesterday I was processing some images on my PC. Was using LR and linked to NIK Define to touch up some noise. Define had an issue and locked up. Tried to kill it every way I could think of, but nothing worked...not even killing the process from Task Manager. I had to reboot the computer to remove the hung up application.
That is why I'll not be getting another PC...too much frustration and too much driver incompatibility. Done.
LR used to seize up on my i7 Mac Mini all the time... there are faults to both systems. Windows 10 has drastically improved driver issues, W10 is fantastic at automatically keeping most drivers up to date.
