> Haven't memory speeds progressed a fair bit? Not really, no. Over the last 15 years CPU memory bandwidth has increased around ~10x. Meanwhile monitor resolutions have also increased around ~10x. Meaning per-pixel CPU bandwidth has been flat over the years or even regressing a little bit. Laptops have become more common yet they also lag on memory speeds, or sometimes are even just single channel. Yet they also tend to have the highest resolution displays, not a great mix if you're trying to make CPU rendering still be viable. As for your Mac issues I think you just have a broken computer. Software shouldn't be designed with the expectation that it'll be used on broken systems, that's not a realistic design constraint.
