It's VRR related - so GSYNC in this case
Flickering will be worse the higher the refresh rate
I've not had the flickering that bad, only ever get it on loading screens but is GSYNC really necessary on a 240hz monitor? Genuinely interested, because GSYNC is mostly needed when your fps is between 30-80. After that tearing will become a non issue with a 240hz monitor. You won't get flicker between 40-80fps so no harm using GSYNC in those demanding games, but games that run closer to the 240fps range won't benefit from gsync anyway so may as well turn it off and lose the flicker..?
Or am I wrong? Maybe worth trying
G-SYNC is used to allow games to run up to the refresh rate of the display without screen tearing or judder.
Regardless of the refresh rate, you will still experience screen tearing at high refresh rates with V-Sync or G-SYNC turned off. And if you use V-Sync instead of G-SYNC then you will experience judder unless the framerate is exactly locked to the target refresh rate, e.g. 60 fps for 60 Hz, 120 fps for 120 Hz and 240 fps for 240 Hz. Any drops below that will manifest as judder with V-Sync enabled or screen tearing if V-Sync (and G-SYNC) are turned off.
The whole point of owning a high refresh monitor is to allow the gamer to play games up to the max refresh rate of the display, 240 fps in the case of the 32" AW3225QF and 360 fps in the case of the 27" AW2725DF. No game will ever have a perfectly locked framerate, unless you cap it really low, but this is where VRR is supposed to be useful because it syncs the monitor's refresh rate to the output of your graphics card for a smooth gaming experience at *any* refresh rate and framerate.
That's how it is supposed to work but on these displays VRR flickering is a persistent issue due to the way the panels work. The gamma shifts due to the changing electrical output to the screen, which switches near-instantly causing a flickering effect. Other display types such as IPS do not have this issue. It is mostly noticeable on game loading screens where the framerate can fluctuate wildly but I have also seen it in brighter games too, albeit it is more subtle so most may not even see it at all. And if you enable G-SYNC for Fullscreen and Windowed mode then you get to enjoy VRR flickering on the desktop wallpaper as well. It's awesome...
... except it's really not!
My understanding is that display manufacturers can try to reduce the flickering by having the display automatically adjust the gamma levels to compensate for VRR, at least that is my understanding. I always assumed this was done via the graphics driver and why monitors need to be certified as G-SYNC compatible by NVIDIA but clearly this isn't the case as the AW3225QF is a certified display but yet still has flickering with G-SYNC enabled. Not sure if having a hardware G-SYNC module would improve this issue. My previous ASUS PG279Q had a hardware module and G-SYNC worked flawlessly with it with absolutely zero flickering. These usually had an extra £100 to the display though and only used in a handful of monitors these days with G-SYNC compatible being the main one.
