don't think it's a port limitation no matter how you swing it.

"I would AMD let to do their part with VESA as always. And all of us will benefit in the end. AMD users with nice feature to have and nVidia users with add-in cards cheaper than now as nVidia will be forced to lower price." In the end its good to have cheap/free tech for everybody but I will support companies who actually do innovations to get some more. If we always supported copycats there would not be the innovations to share. I don't want companies to make money with the same stuff for forever, but for some time is just healthy and motivating.

G-Sync is a hardware solution, and in this case the hardware resides inside a G-Sync enabled display. NVIDIA swaps out the display’s scaler for a G-Sync board, leaving the panel and timing controller (TCON) untouched. Despite its physical location in the display chain, the current G-Sync board doesn’t actually feature a hardware scaler. For its intended purpose, the lack of any scaling hardware isn’t a big deal since you’ll have a more than capable GPU driving the panel and handling all scaling duties.

The first G-Sync module only supports output over DisplayPort 1.2, though there is nothing technically stopping NVIDIA from adding support for HDMI/DVI in future version

AMD applied for a patent on this back in 2006. It would appear, based on the patent filing, that nVidia is actually the copycat.

I like Nvidia´s GPUs but their stupid attitudes are really hard to ignore. Saying that they won´t share G-sync with AMD no matter what and that AMD should develop their own solution like that it´s really being an huge ass!!! This way G-syng is gonna flop like Physix and the biggest loser is going to be Nvidia because someone will release a non proprietary solution that is gonna work for everyone... Some guys just don´t learn...

It is just a personal meaning with a red tint. Don't do this to your zelf. AMD does the same things bro, open your eyes or get transparent glasses

All companies do this. Imagine if Intel spent all the time and money researching new technologies for CPU's and just gave them away to everyone else to use for free. Nvidia keeping this for themselves may be bad for consumers but to give it away is a stupid business practice. And the main purpose behind a business is to make a profit.

Not to mention people who buy AMD aren´t going to buy GPU´s from Nvidia because of G-sync, but okay this is just my opinion.

Until the monitor industry implements display port 1.3 , it's a moot point, Nvidia is selling hardware and that costs money to develop and market.

And that is why I no longer buy nVidia GPUs. I do not want to support business model which intentionally locks everything they make on multi-vendor platform.

Not putting in the work to make your competitor work with your technology and intentionally locking your competitor out are two different things. Not only that, but to make it work, nvidia would need to know the workarounds for AMD's hardware/software, and i can guarantee you that AMD won't give that up

I agree that Nvidia shouldn't have to share their tech, but if they did Nvidia wouldn't need to do anything. The GSync module really isn't that complex according to every review article out there. AMD would just need to know how to interface with it in their drivers. They could figure that out on their own with some reverse engineering--they simply need to be allowed. Again, not that they should be allowed. But ultimately the entire issue comes down to proprietary vs. open standard. Traditionally, proprietary formats eventually fail. IBM had a 98%+ market share of PCs when they decided to get greedy and make a proprietary mouse and keyboard socket type called PS/2. The competition banded together to create an open industry standard. Now we have USB and IBM is a shadow of its former self. There's a strong possibility of Gsync having a short life span because of this. Remember that it's not just a fight between Nvidia and AMD. The grand majority of PC users are on integrated graphics so Intel has a stake in this, too. Intel and AMD already have a working relationship processor-side, I wouldn't put it past them to develop a competing technology and possibly even make it a VESA standard.
