AMD's Low Framerate Compensation For Nvidia ?

Dunno about day one but G-SYNC has a certain amount of such functionality already - without more details dunno which solution is the more sophisticated though.

I think Gsync has been doing this from day one.

Well I was just watching an AMD video and they were talking about when the games FPS goes below the Freesync threshold which on some monitors is 35Hz, LFC kicks in and considering G-Sync is limited by 30-165Hz currently I was curious.

G-Sync works all the way down to 1 fps Dice.

G-SYNC has some functionality to improve the experience when the framerate drops below the G-SYNC minimum and to minimise the time taking to recover when the system is capable of rendering at a higher framerate again.

Unfortunately I'm not upto speed on the exact implementation.
 
Gsync will only match GPU and monitor within the Gsync range so 30hz - 144hz each frame will be synced.
When below 30hz the monitor will double or even triple each frame at Max fresh rate of the panel..

This helps keep smooth motion when frame rate is low.

Gsync will not match frame rate below 30hz for example 20hz won't be 20fps nor will 1hz be 1 fps etc

They is a bottom line that needs to be draw before a display will start to flick or worst damage and I believe that is 14hz is the breaking point.
 
I might be wrong but I think G-SYNC starts duplicating frames in low framerate situations and starts rendering at higher multiples of the refresh rate instead of dropping down or capping at a lower refresh rate - which it can do thanks to the FPGA and freesync can't apparently. Which means that when new frames are available at a higher rate than the current one it can display them more quickly on the screen while with freesync you have to wait for the next update at the current rate before it starts increasing?

Not sure what amd have done on the new system but I think they now also added in frames and put monitor back on max refresh rate I'll after watch pcper amd driver video or write up.

Like above I sure Gsync has had this from start it's one thing pcper tested that time with fancy tech they was using..

Yup that's where I remember seeing it, they had it still smooth at 9fps....as if we would want to play anything at 9fps.
 
Some of that information in the video is outdated btw - G-SYNC now allows you to run above the refresh rate of the panel with V-SYNC off in G-SYNC mode. (For those keeping score AMD did that first however).

Can't remember seeing that I think they stopped around 20 something fps.. But even still the display will not be 9hz Gsync would put the display at 144hz @9fps and add in frames toll they match the refresh cycle.

Below 30hz Gsync just keeps adding in frames @144hz.

Anyways anything 30fps just isn't enjoyable no matter what tech we using..

Frame latency and input lag just can't be fixed 30fps is 33ms lag what is 9fps or 20 for that matter lol
 
To be clear this is not the first time this type of technology has been released as NVIDIA’s G-Sync has already had the feature present since its launch. This was possible because of the embedded hardware module that comes with every G-Sync monitor. Since AMD’s FreeSync does not have its own module the company has resorted to using software to implement this function.
