Is laptop gsync software gsync like gsync compatible monitors or the more traditional hardware gsync

    I ended up reading in a few places that laptop gsync is really just software gsync using a gsync compatible gpu and gsync certified panel. From what I understand that this is more akin to gsync compatible monitors than the full gsync monitors with the gsync module inside it. I've read a lot of posts detailing quirks and higher input lag with this type of software gsync so I was wondering if laptop gsync worked the same way.

    I'm at a cross road when I'm deciding if I should pay extra for gsync or not, so this is make or break deal for me. Unfortunately I haven't been able to find solid information on this.

    Edit: This was one of the places https://arstechnica.com/gadgets/201...c-for-laptops-reveals-low-level-tech-details/

    Does this make laptop gsync inferior to monitors with the module?

    From what I recall the display is driven directly off of the GPU so there isn't a module needed and it should work like a hardware implementation.

    Yeah you're right. It was explained in the article above and reflected in this analysis
    G-sync using a monitor with the module introduced 0-1ms lag, where laptop g-sync introduced a few seconds more of latency. Overall not a big deal, its a very small amount.

    The average latency difference between the 60Hz laptop and desktop monitors when G-Sync was enabled is less than 1ms, which is within margin of error.

    It wasn't within one second. The 60hz laptop had a 3ms difference between gsync on off, and the 75hz laptop had a 5ms difference between on off, but the desktop monitor had roughly 0-.5ms difference between on off. His data was an average of 20 tests too.The difference was 3-5ms, not 1ms.

    I don't think we're talking about the same thing...

    You're comparing the wrong direction.. all that shows is the difference between a completely different monitor and panel. The relevant data is the deltas between gsync on and off. Compare those between the panels and monitor. So basically the differences between the first two bars for each column, or you can use the third and bar and subtract it from the first. You'll see that enabling gsync in the desktop monitor introduced basically no latency while the other two panels introduced roughly 3~5ms.

    Well, his results are a bit different than what Blur Busters measured on a desktop. If you go here and scroll to the bottom of the 60Hz Overwatch page, going from No Sync + 58 FPS Limit to G-Sync + 58 FPS Limit to G-Sync + VSync + 58 FPS Limit adds a few ms of input lag each time.

    Why would they be the same.. they're different tests done on different devices using different testing methodologies in a different environment by different people.. you can't just compare apples to oranges.
