oh bs, where do you get your info from? You do realise that will still mean a new monitor - that tech has been around for ages in laptops as a power saving function and no-one has even seen it work on anything else yet. So please tell us how it's too late troll.
gsync first impressions have been very good and more importantly, it's here now - retrofit or not.
It's not for everyone and it's not an nvidia vs ati debate topic, I want both to do well as it's only good for the consumer.
For now I don't need it, but for future generations and newer/very demanding games, I can see myself adopting it in a year or 2, depending how the market develops.
1.2a is ready. Controllers compatible with it probably are too, since the mulled spec has been known for a while. Previously it wasn't known if adaptive would go into 1.3 or an interim (1.2a). It doesn't require much ... unlike a currently vapourware entirely proprietary NVIDIA technology that requires panel manufacturers to use an NVIDIA controller and pay licensing fees on top of that and also requires you to have an NVIDIA graphics card.
This is the entire reason for the paper launch. NVIDIA were desperate to capture the market before an open standard dominated. They're a bit late and will likely offer little more than solutions using 1.2a / 1.3's baked-in adaptive synch support, except of course additional cost and headaches for monitor makers and consumers.
