I have a MacBook in my closet I can’t use at all because of an Nvidia integrated GPU. I’ve had nothing but problems with their shitty software too. Never had a single problem since I switched to AMD, and it was wayyyy cheaper. Your issue sounds like PEBCAK to me.
You know opencl AMD installations have problems if you have previously installed Nvidia software? So it sounds like your experience with AMD may have been soured by NVIDIA actually, and then you went out and gave them more money.
