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..
