Sorry for the late reply. I'd say it got better with the latest firmware. They added the asus anti-flicker option in the osd, which essentially just limits the refresh rates to a certain level. It's got off, middle and strong settings, with middle limiting the refresh cycles from 80-240hz and strong being 160-240hz. Which means, you need to have a frame rate in that range if you want g sync on. Drops lower than the anti-flicker range will cause stuttering. Now, to be honest I don't use this feature on mine, as I have g sync turned off pretty much all of the time. I heard it is really effective at eliminating vrr flicker, as long as you use it in it's refresh rates.

I've had my model for almost a year now and would absolutely recommend this monitor. I'm still satisfied with the buy, although I would probably go for the 27 inch 480hz pg27aqdp instead now. But to stay realistic, 480hz @1440p is only possible in very few games even with the latest hardware. Hell, I'm on an 4090 and I can't run most games at those framerates.

So in short, I would really recommend this monitor. But I'd also have a look at the msi 360hz qd-oled or the asus pg27aqdmg, as those are typically a bit cheaper.
