I haven't seen anything which is a huge disappointment. Nvidia just loves the extra profit from selling gsync modules instead of supporting open standards.
If GSync was actually better, there would be no reason to not support both. A "Budget" Adaptive-Sync and a "Premium" GSync for any gamer.
They released "FastSync" which is basically tripple buffering and already available in windowed mode in windows 10.. woopie.
