Suddenly, no access to GPU settings in preferences
A few days ago, I tried to use the previously working face aware sliders in Liquify. However, all the values were greyed out, the sliders were unresponsive and there was an exclamamtion mark next to the face aware heading itself. The value in the adjacent woindwow was also greyed out.
At the same time, I found that I was unable to access any of the GPU settings under the Performance preferences tab. See the image below.
I shoot headshots and tidy things up within Liquify quite regularly, so this is a big deal for me and I'd appreciate any advice as to hpw i can get things back to the way they were. I've tried reinstalling PS to no avail, and have determined that the GPU(s) in my laptop are working. I'm using a Macbook Pro running Catalina (OS 10.15.7) and everything was fine until a couple of days ago. My graphics processor is a NVIDIA GeForce GT 650M.
Thanks in advance!
