using 496.49 here also don't use GeForce experience hereSeeing as you have the same CPU/GPU as me and you're saying it's fine - what drivers are you on? I downgraded to 472.12 (September drivers) and it's made a big difference, it's still not perfect - but it's a lot better than the current latest ones Geforce Experience asks you to download.
Just curious which driver version you're on,
