This is relevant to tests I’m about to post regarding the Apple 2021 MacBook Pro M1 Max, because OpenCL gave me fits in testing.
Everything written in OpenCL is being rewritten for Metal on macOS this year. OpenCL and OpenGL are dead.
I believe SmartSharpen is at the top of the list to move to Metal off of OpenCL.
OpenCL is a mixed bag. It’s actuallly slower than using CPUs for some Photoshop filters, but for Smart Sharpen it is a major win.
