    Unlike NVIDIA's G-Sync, no specialized hardware is required to support FreeSync. This week at Computex, AMD was showing off the first FreeSync capable monitor
    Really dude? That's a contradiction right there, you need no specialized hardware except *cough* a FreeSync capable monitor with DisplayPort 1.2a or newer + a card with the same specs (and I assume an AMD card unless Nvidia decide they want to support it too)

    Standalone monitors as is typically do not support this technology meaning you DO need specialized hardware. You just don't need that expensive GSync chip. I hope Nvidia responds to this by supporting freesync as well.

    But judging by the differences that GSync is a much more complicated implementation of this, I am sure there are benefits it has that freesync does not (not that I care, I prefer freesync because it's hardly any extra price for me to get that)

      "No specialized hardware" Means "No hardware who's sole purpose is to make this work." DisplayPort 1.2a capable monitors and cards would have found their way out into customers hands eventually.
      All opinions are my own not those of my employer if you know who they are.

        Do games or layers like SDL need specific code to support this?
        I think this will be implemented so that applications don't even have to know its there. It's basically just adaptive vsync except that the PC/GPU triggers the monitor redraw start.

        I read somewhere that AMD will support it on all GCN 1.0 and higher GPUs. On the monitor side you need new hardware of course.
        I wonder if this will help with Oculus, too.

          40-60Hz?

          I think G-sync was meant to go with 120-144Hz monitors, which help with mouse lag.

            In the video, the guy mentions that the spec allows for variance from 2-240hz, and the monitor picks a slice out of that and reports it to the GPU as what it supports (for example, 40-60hz). The monitor in the demo is an already released monitor with a special firmware upgrade, so that 20hz variable is probably the best it could do.

              Feature for power nazis..

              Correct me if I'm wrong.......but the ONLY advantage that this adaptive-synchronization thing offers (compared to normal vertical-sync) is that is can reduce power usage a little of your monitor by dynamicly lowering the frame-rate at times when you are viewing low frame-rate stuff.. Right?..

              The last time this was posted on phoronix, a lot of people were cheering about finally having tear-free games......but that's stupid, because v-sync has already done that for eons..

              I guess some people just don't understand what they are talking about some times.. Oh well.. At least I do..

                Lol... Troll is ALMOST successful. Next time tone down the elitism. For the record of everyone else... This is not a "power usage only" feature. This IS about fixing tearing and stuttering

                  Might be worth calling around to find out which companies have this extension and a firmware update. Might save a bit of cash.

                    V-Sync introduces GUI latency unless you've got a monster video card because if a frame is a few milliseconds too late, it has to be either discarded or delayed to the next refresh interval.

                    Adaptive sync lets the video card say: "This time, we're doing 59Hz rather than 60Hz so I can still immediately display this frame I just finished."

                      It is meant to fix stuttering.

                      If a new frame isn't made available to the monitor in time for the next refresh, the monitor will keep the old image for 2 frames, before eventually jumping forward.
                      This technology tells the monitor to wait slightly more than 1/60 seconds because the new frame isn't rendered yet.
                      This wouldn't be much of a problem if you have a really high refreshrate, or a really fast graphics card.
                      This is just common sense, and everyone is surprised it wasn't already like this.

                      G-SYNC technology is officially in the house... My house, at least, but don't worry you'll be able to try it for yourself fairly soon...Sponsor link: http://...


                      Powersavings is probably extremely minor.
