Is it possible that the G-SYNC module from my monitor is bugged ?

Hi everyone,

Lastly I was playing around with my new Asus PG27AQDM monitor (OLED 240hz).
What is strange to me is that, when I cap my FPS, enable V-SYNC, enable fullscreen only G-SYNC and enable the Adaptive Sync option on both of my monitor OSD, there is a clear night and day difference in fluidity perceived.
Let me explain.
My second monitor is an Acer Predator XB273UGX 1440p 240hz IPS monitor.
When I play games on it with the options listed above, its butterfly smooth, no jiggering, no stuttering, its not choppy at all. 144 fps feels as much as fast as 240 fps.
But when I'm playing on my new Asus monitor, Jesus Christ, when my FPS drops in the same game around the 140-180fps area my game feels so stuttery and choppy, its crazy.
I've already disable other plausible variables like two monitors plugged bug, overheating, back application bugs and stuff like this.
I've tested the same game (Warzone), same map, same option, just on different monitor.

What is making me thinking that my Asus monitor is faulty, is that on the monitor's OSD it is showing the changes in Hz that the monitor is doing with G-Sync. Checking with MSI afterburner and in-game FPS counter shows to me that the monitor is not properly syncing at the same framerate as my game is running. Like Warzone is running at 180 fps, monitor OSD will show me refresh rate hovering between 180, 160, 229, 240, 150. Its bizarre and I don't know if its a normal behaviour from my monitor. Firmware is up to date. Tried resetting and multiple G-SYNC settings, even running the monitor alone without the second one.

G-Sync bugged ? OLED normal behaviour ?

With many thanks.

I want to add that on my NVCP on the G-SYNC section, my Acer monitor is showing (G-SYNC Compatible) under his name but not the Asus monitor, which is strange since both has the same Adaptive Sync module.

It's normal; those meters are approximated, they average differently than system-side readouts, and sometimes include LFC multiples, so that, at least, is not a sign your monitor is faulty. Said monitor meters are only really useful for determining whether VRR is currently engaged; static = not engaged, fluctuating = engaged.

I've already told you in your other thread the only thing I can think you are describing is OLED judder based solely on your descriptions, or maybe LFC triggers too early or late at default.

I'd have to experience it in person to say anything further, and that's not gonna happen, so the only choices you really have at this point are to 1) exchange it for a replacement to rule out whether it's your particular unit or just the model, and/or 2) contact support if you're outside the return period.

I re-checked, and neither of your monitor models actually have a G-SYNC module; they're both FreeSync displays with G-SYNC Compatible (software-level VRR) support.
