My OLED (C8) is unfortunately a year too "old" to support this update, but I do hope adaptive synchronization is widely adopted... or something like it. I am FAR more interested in the proper handling of frame rate and color information than in the mindless push for more pixels. I'm quite frankly tired of so many high-resolution games that chug along at 25-30 fps. They make pretty screenshots, I guess?
This kind of adaptive synchronization does introduce some latency, but my understanding is it's a much smaller latency window than traditional vsync methods. For most games, I'd much rather have a little latency than screen tearing and stuttering.
