    Hi. I have 2080 Ti and 9700K and monitor AORUS AD27QD. So today first time i saw a light flickering/pulsing on grey walls in game Control when fps was 45-55fps and in Quake 2 RTX on 49fps.

    I disabled GSYNC flickering gone,also i enabled again GSYNC and still gone ,fine. My question is is this normal that reenabling GSYNC helped? And why i had flickering on such fps?

    Probably just a bug in the game or your GPU driver version. I have seen some games that have weird behavior with v-sync enabled as well. And, others that have weird behavior with v-sync disabled. That's just how things go sometimes in the world of computers. I doubt you have a hardware problem.

    First your monitor is G-Sync 'Compatible' not real G-Sync. This means it's missing the physical G-Sync module and it's really just an adaptive sync/Free Sync monitor that Nvidia has found to work relatively well and meet most of their criteria to let the monitor manufacturer put the G-Sync branding on the box. What you're describing sounds like low frame rate compensation issues as you exit the adaptive sync range. Usually 48Hz/FPS. Keep your fps higher than this and the issue should be resolved.
