I've been testing some work units on my 2017 MacBook Pro to see what will actually run on the discrete GPU. For some context, the computer has both an Intel "integrated" HD Graphics 630 and an AMD "discrete" Radeon Pro 560, and can dynamically switch between the two, based on what is needed. Both are listed as "device 0" on their separate buses.
So far, I've gotten AP and WW to work with the AMD GPU, but PPS-sieve and all GFNs try to use the Intel device and fail. Has anyone else gotten PPS-sieve or GFN to work with this configuration? I know it's a niche setup, and if there's no answer, it's not a big deal. I'm enjoying chugging through WW work units.
