Last week we got Ableton Live 12.2 released. It has an entry in there that's just a single line:

"On Windows, you can now enable a hardware-accelerated GPU renderer to significantly improve Live’s UI performance. This option is disabled by default but can be enabled in the Display & Input section of Live's Settings."

This is years of work. Maybe one day I'll tell the story somewhere. There's no groundbreaking algorithm or graphics technique in there, just many engineering steps..

The gist of it was taking an immediate mode software renderer (function calls) first into a deferred renderer (serializable, replayable command lists) that then get "interpreted" to Metal then D3d11 graphics APIs.
@uucidl Only vaguely related, but thanks for working on Live; my first Midi controller came with a copy of Live Lite 8(?), and I've been enamoured with the interface ever since. Even done the occasional mashup in Live Lite, versatile piece of kit.
@Two9A Glad you’re enjoying it!
