Sonoma UI feels great. I'm also excited that they finally fixed Quartz Debug — the "Enable Vertical Sync" option finally works again when disabled. My mouse feels snappier and there's noticeably less delay when moving windows around.

You mean there is less delay when VSync is off, right?

  Yep!

Is that meant to say “disable”?

Quartz Debug. That’s a name I haven’t heard in a while.

  It's still being updated and included in the "Additional Tools for Xcode 15"[0] and is the only way to disable vsync/"Beam Sync" at the os level using Apple tooling, afaik. Beamoff[1]/beamsync.py[2] are good 3rd part solutions, though. I use my m1 mbp in clamshell mode connected to a 75hz 1920x1080 ips all day every day, so until I can buy a monitor that supports adaptive sync, the reduction in latency that disabling vsync brings is worth it to me.
