Hi,
I bought a new monitor not long ago. It's a Dell S3422DWG 34" 3440x1440 144 Hz VA ultrawide.
It's an absolutely amazing monitor, but I've noticed that I occasionally get some weird backlight flicker in some games. After looking into it, I found this:
Basically, if you have a Variable Refresh Rate display with Low Framerate Compensation (LFC), and your in-game framerate comes close to, or drops below the display's VRR range (48 Hz in my case), then LFC kicks in, doubles, or triples your refresh rate. So, if you have 50 or 55 FPS, for example, the monitor will switch to 100 or 110 Hz momentarily to stay within VRR range and avoid screen tearing. This comes with blacklight flicker on some displays (mine included), which is extremely annoying.
The question is, is it possible to disable LFC without disabling FreeSync somehow? I generally have no issues playing at 48 FPS, but the flickering makes it really bad.
Another question is, what else can I do to mitigate backlight flicker with LFC?
I would like to avoid using CRU and any kind of custom things that aren't part of my display's official support if possible.

What Is VRR Brightness Flickering And Can You Fix It?
On some gaming monitors (mostly VA and OLED), VRR can cause brightness flickering with FPS fluctuations. It's possible to reduce or fix it.
