I am having the same aliasing (?) issue in every game. The only way to fully alleviate it is play a game on 4k with TAA enabled, but thats too demanding and many games just don't have TAA available.
And on some, the combination of 4k + TAA doesn't fix it but just alleviates the issues somewhat. Nvidia tech support has told me to delete and reinstall my drivers, which I did, but nothing changed. Perhaps somebody knows of some easy fix or some other method of reinstalling drivers that might help?
