lighting effects grayed out
I find it odd that lighting effects is grayed out in my photoshop cc2018 but I can use it in Photoshop elements 11! Why would that be?

from Edit -> preferences -> Performance:
make sure " use Graphic Process " is checked , and make sure your graphic card driver is up to date too.
Restart Photoshop, and let us know if that helps.
