Maybe I don't completely follow but it sounds like you're saying Mac users don't have latency problems. That's clearly not the case, hence the reason for my confusion. I almost never have latency problems with my PCs - the last 3-4 machines I've built run just fine at 128 samples with no tweaks to anything (except the laptop shown in the video, but I haven't seen latency measurements on a Mac booting from a PCIe SSD either). But clearly there are folks who do have problems with PCs. The only thing PC specific in the video was the mention of the latency checker tools. I assume there are similar tools for Mac but I'm not sure what they are.Great work Richard! One minor suggestion: a lot of what you talk about with the Bios, various video cards, are mostly PC only issues as Macs are designed to include components that work together optimally and higher quality than some PC makers or DIY guys choose. So perhaps the tile should read:
CPU Performance vs. Real-Time Performance in Your PC DAW
Regardless, Macs use all the same hardware that you get from HP or Dell or VisionDAW or whomever. Macs still have a BIOS. Macs still have video cards and hard drives and USB hubs that interrupt the processor for processing. And all of those devices are the same as on PCs. It is true, of course, that you have fewer options to tweak those devices on a Mac. But it's not because they're different or non-existent.
So I think the video applies perfectly well to both Mac and PC.
