Hi, I'm using an asus pg279q connected via DisplayPort to the GPU. I have G-Sync enabled in the nvidia CP and i thought it would cap the fps at 120, because the refresh rate I have set is 120hz. But it shows the cap at 144 fps. I don't what to do to make gsync work properly...

Any ideas?

The simple way to check it if the monitor is running in G-Sync mode is to have a look at the Power LED.

If its Red, G-sync is on. If its White, it's not.

As for capping framerate, V-sync must also be enabled in conjunction with G-sync to do it. Without it, G-sync will only match your refresh rate to your FPS output if it remains below the...


Most of games reach 120fps at 2k, but 144 it's pretty hard. And I don't even know if gsync works because it doesnt cap the games at the same fps as the refresh rate. Is there any way to check if it works?

Thanks for your answer.

Simply apply V-sync globally using the Nvidia CP (don't worry, you dont get any of the issues associated with V-sync with g-sync enabled).

If I were you Id run your monitor at 144hz, and then use a program like Rivatuner to cap FPS at 120. In most games that I cant run at 100fps+ the whole time, I cap them at 90fps to stop any wild spikes, and it works perfectly.

I had vsync and gsync enabled but it stills cap games at 144, anyway, i'll put the monitor at 144hz and yes, the power led is red.
 
Ok, in that case G-sync is working fine - it just doesn't like being set to a below-native RF it seems.

Running at 144hz and capping games to a lower FPS is the only option I figured out with mine, and it's one that Im happy with.
 


Yup, thanks for your time.
