The last couple of times my Open CL has quit working I was able to slap it back to life by turning off "use graphics processor" restarting PS and then turning it back on. Now that doesn't seemt to work.
I'm on release 21.2.3 on an iMac with an NVIDIA GeForce GTX 780M 4 GB video card. Any ideas?
I miss my oilpaint filter.
