AW3423DWF, flickering while using frame generation

Hi, 

I have an issue with flickering in darker greyed scenes that my monitor is flickering when i enable dlss 3 frame generator (gsync enabled). So in example in star wars outlaw with using only dlss quality and get 65 to 75 fps i do not get flickering but when i enable FG and i get from 80 to 100 fps my monitor flickering like crazy... Even if i lock my fps about 80 fps it still flicker even when the frames are locked and do not fluctuate. Same issue i have in ghost of tsuhima, cyberpunk 2077... Always when i enable FG i get crazy flickering. I use rtx 4080 super. Any help?
