I'm playing online. I haven't tried offline yet, but I'll test when I get the chance and report back. Seems really shoddy that it would run like that online when D4 is fine.

It doesn't look like Ray Davies to me. Very interesting show, it's kind of like Black Mirror if it was done in a more experimental pseudo-documentary format. It's about the "Video Age" lol.
Works great at 60fps on my M1 Max mbp, but a) you really have to use it on the Sonoma beta for the least problems. I made a Sonoma beta install on a separate SSD to not mess up my current install. And b) updates to Battle.net can break it, so you have to reinstall Battle.net if that's the case. Not a huge deal but that means going to terminal and inputting commands, etc. Not ideal. There are other programs that are supposed to 'smooth' out the install process, like Whiskey, but I haven't tried them.
I spend about 90% of my time in macOS because it's what I use for work, but like you I have a long history with PCs and still build and maintain them mostly for gaming and testing. Macs are overall a more polished and integrated experience, and it's the attention to detail I like the most (not that they're perfect of course).
Some examples upon many... Windows 11, which I use on my main gaming PC, STILL doesn't have a consistent dark mode. Basic windows like disk operation progress are white still. You still have to dig into control panel at times for certain things, even though they continue to add more things to settings. You still have to deal with drive letters. Installs now REQUIRE an MS account, even though the workaround still works. Overall it works fine, but there are a ton of things that bug me.
As for talking with people, well living in SoCal it's not a big deal because the overall market share for Macs is pretty high regionally. So everyone is familiar with them, and if I had to guess, 80% of the people I interact with are Mac users even though most also use PCs for certain things.
I think I already did try turning vsync off but not 100% sure, and if I did, I didn't test it for that long.
