I have 2 monitors on Quad-HD and 4K, I use my 4K monitor for gaming.on what resolution are you gaming?
which details are enabled?
anything used like afterburner or similar tuning tools or geforce experience or settings altered in nvidia driver?
set all to default settings
maybe use ddu uninstaller and reinstall latest nvidia.com drivers
My settings in game are always medium, as I prefer performance to quality. I didn't change any nvidia panel settings, they are all default I will do the clean drivers reinstall with DDU and will send you the result
