One thing though: Did you play around with enabling/disabling SLI? Many G-sync users have reported incompatibility or significant stuttering while in G-sync mode with SLI enabled."

Thats good to know. I had not even considered that SLI might cause issues with stutter. The only game that I saw any strange results in rendering with was Assassins Creed 4. I have been playing BF4 and Diablo 3 ( which, admittedly, doesn't benefit at all from Gsync ) without any issues at all. My framerate is locked at 140 on ultra and rarely dips below that number at 1080p.

I'll do some tests when I can and get back to you on that. I will be out of town for the week so it probably won't be soon.

Awesome. Looking forward to your tests.

After researching FreeSync and GSync for hours and looking at the 2 technologies, how they are executed, and taking some of the things nVidia engineers said in interviews into account, I came to the conclusion that it is very likely the same technology, thats all. "FreeSync" was in quotes because its just a buzzword -- marketing, just like the label "Gsync".

If Gsync indeed does use DisplayPort VBLANK as the basis of its implementation, then they are very much the same thing. nVidia simply added some hardware to make it viable in current display port setups instead of waiting for DP 1.2a or DP 1.3, thus pushing the market toward progress. Keep in mind that both nVidia and AMD are VESA partners.

Also, I will say it again to make it clear -- this is only a theory that I came up with after reading up on both technologies. I could be way off, but I nerd out on this stuff and find the details of implementation fascinating. smile.gif

Thanks for the extra info. smile.gif

After looking at those threads, the one most relevant to my situation is, of course, the 780 SLI thread with Battlefield 4. I will say that I have not experienced any of these issues on my EVGA 780 Ti OC Edition cards. I get high framerates, and no stutter at all. If anything, BF4 became slightly smoother after installing my GSync kit.

I am using the 337.50 Beta drivers. Maybe that is why?

There's nothing simple about the hardware they're adding. Nvidia is spending an enormous amount of engineering time on implementing G-Sync displays. One display OEM, Overlord, reported that they have to hand-tune each G-Sync module for each panel type that the display OEM wants to use, and that the bottleneck to getting their own G-Sync model rolled out was due to Nvidia's design resources.

The issue, and the reason for some...vigorous...comments, is that AMD is expecting the display manufacturers to do the work on their own. They've announced no partnerships. They've announced no direct support. In fact, their announcement of FreeSync stated explicitly that they brought it up to "encourage" display manufacturers to invest in the technology. Which is why I get a bit riled when people claim that FreeSync is 100% awesomely better than G-Sync because it's free (it's not) and open (sortof - if it ever exists). It becomes another pawn in the Red vs Green chessboard to them, and facts fly out the window. I prefer facts, and so attempt to refute the spin that the internet has generated but that statements by AMD itself directly refute.

It is very clear from the info we have so far that some sort of vblank extension is how G-Sync works. The devil, however, is in the details, and those details are what Nvidia is expending time and money into figuring out, and then charging us for the results of that effort.

So then, what yo're saying is... that we agree? tongue.gif

No seriously, that's what I was trying to say (Including the hardware tuning). It is my belief that the Gsync module simply handles the work of doing the VBLANK calls to the monitor, which would require timing and tuning. I never said that Freesync was better -- just that they are the same tech.

There's no argument here, friend. I want whichever side has the best frame rates with the prettiest graphics to win. If Intel released a card tomorrow that smoked both AMD and nVidia's best offering, I'd be lining up to buy one. I play for no side, I just like tech.This particular tech is good for the industry, so I'm on board no matter who makes it.

No....

The answer to this question has been said so many times in this thread already. Here is the summary....

  • It is a true 8-bit TN panel, versus the standard 6-bit
  • A new type of TN panel; new materials and production methods
  • It has near PLS/IPS color reproduction
  • Better viewing angles than other TNs


All while maintaining the ~1ms response time of the typical "gaming" TN panel. Everyone that I have spoken with that have seen this panel in person all tend to agree with the above points. The blacks on it should actually be better than IPS, which honestly isn't very hard to do.

The proper response here is "I don't know."

The only thing ASUS has hinted it as that it will have better image quality than the VG series. I'm typing this on a VG248QE, which is sitting right next to a QNIX PLS panel. The difference between black levels and color reproduction is VAST. The only thing the VG does better is motion clarity. It gets blown away in every other category.

I really don't know why you feel the need to make claims about the image quality of this monitor when you haven't seen it in person. You have no empirical evidence to support these claims.

Except for the "people who have seen this panel in person." Those people do exist.
