I'm surprised no one has actually tried it. Kinda sad. I ain't paying extra for g-sync proprietary DRM crap so I'm getting the freesync regardless. I can always use it when I buy an AMD 390x.
It doesn't. If you're talking about AMD's CES 2014 demo, that was just v-sync at a fixed 50hz refresh rate. AMD's first convincing demo of variable refresh was a year later, at CES 2015 (after engineering samples of the new adaptive-sync scalers were available.) https://www.youtube.com/watch?v=pIp6mbabQeMRLBURNSIDE wrote:If it has nothing to do with DRM, why does it work on older Toshiba laptops that were released prior to the development and marketing of G-Sync?
Nvidia's g-sync implementation came before freesync, and relies heavily on hardware inside the monitor. Much of that work has to be re-done inside the driver in order to support variable refresh over adaptive sync. It never was a question of signaling, that's just data. With adaptive-sync, It's finding how far you can push the timings on a monitor before you ruin image quality or the monitor stops working, making your drivers use that whole range, and coding your drivers to handle fallback cases for when framerates go outside the monitor's acceptable range. g-sync kind of does the opposite, with the monitor accepting any framerate, and doing whatever it takes to display a frame on time.Assuming for the sake of argument that G-Sync module over Freesync isn't purely for DRM, if eDP monitors support variable v-blank without special extra hardware from NVidia, relying solely on eDP's spec and commodity laptop displayport scalers, I'd like to understand why it's not compatible.
What I'm saying is, I haven't heard of anyone actually trying it. Several blogs mentioned the eDP discrepancy, since if a g-sync-enabling driver can work in a laptop, there's a good chance it should work over a normal displayport using similar, if not the exact same signaling method which has been around since 2007.
Nvidia is doing most of that work for mobile g-sync, but it's not a mature implementation, and they're not going to release it for desktop monitors until there is a business case for it.I'd bet any money if NVidia actually wanted to they could make their displayport videocards work with Freesync monitors.
Until I see someone actually try to use this leaked driver to enable G-sync to a Freesync monitor, I'm not convinced. Toshiba laptop = 2007 edp spec = nothing to do with G-sync-specific hardware.
