@McD Please note that only the latest version (R20 - R23 released after 2020) does not benchmark the GPU, but before that the R15 version did. Go look at the results and tell me if M1 has the same result of 1080 or something like that (and not the notebook version please).
Also what you say is right, the M1 pro is slightly superior to a (non ti) 1060, which is true, but the 1060 is an mid-low video card. Whereas in the benchmarks above, there is a very pronounced disparity as if Affinity was very optimised for apple M cpus and not so much for the others processors. Don't you think?
