Are freesync hz ranges likely to improve in the future?

post #1 of 5
Thread Starter 
Might be a dumb question, can't find an answer. I just built my new computer and was considering upgrading to a 1440p display from 1080p. The best screen seems to be the Asus MG279Q however I see that even this one has a freesync range of only 35-90. I am sure above this, it won't be an issue. Below this I have read people have problems of lag. With my single 390x I will still occasionally be dropping into the low 30 fps at 1440p with demanding games (GTA 5). Even at 1080p now with all ultra/max settings except only 2x MSAA I will still occasionally drop below 40 (usually full 60 fps with vsync)

Is it likely that new panels will be capable of much lower than 35? Or is there some technological reason why this cannot be?

Would anyone wait to see what the future holds (next 12-18 months) or buy sooner?

It is very unlikely new panels will go below 35 fps but the frame doubling method Nvidia does in hardware might be possible for AMD to implement in software. This allows VRR to be effective at any FPS below the max.

The reason current panels will not go below ~30 fps is because the pixels are set by a pulse, not held; after they are updated they fade to another value. If updated less often than every ~33ms the fade becomes significant enough to be visible as flickering.

Someone at a monitor manufacturer claimed here that AMD is working on beta drivers that will support frame doubling, effectively reducing the lower end of every monitor's freesync range by half. No idea when that is coming though...

There is also some convulted way to hack your monitor EDID to pick lower refresh rates, no idea how each monitor would respond to that though.

Thanks for the replies. Sounds like any changes will be in the software so no need to wait before buying.

Is there a physical restriction on freesync continuing above 90Hz as well? As the asus monitor above can do 144 it seems strange to limit it to 90.

It has to do with the combination of scalars, PCB, panels, and some modifications of the monitor's reference Firmware/Hardware - and not FreeSync's limitations. Our monitors are FreeSync Certified for 30Hz to 144Hz.

There are no panels at the moment that do below 30Hz - even Nvidia G-Sync impliments Frame/Hz doubling around the 35Hz/FPS ~ 37Hz/FPS range for some of their monitors to prevent the gaming experience from dropping to 30Hz/Frames and below - below 30Hz/Frames is not a desirable gaming experience anyway.

AMD is working on new FreeSync features - but I can't get into much detail with it at the moment other than it will be implemented through their drivers - no need to do anything on our side as a monitor vendor... AMD will make the new FreeSync features announcement when they are ready.
