The AW3225QF is not reporting the proper EDID information to Windows. By default, the monitor is not reporting VRR ranges, or any HDR or CTA-861 blocks at all. This results in (at least) behavious such as severe VRR flickering.  Please correct the EDID/Handshake with the monitor. This occurs over HDMI and DisplayPort, Nvidia graphics card (although others with AMD have reported the same).
