I have been having intense shimmering on many games. I can tell its a little different than just aliasing, because it is 100% unaffected by whether or not I have most AA settings on. The only things that truly stop it are supersampling and 4k resolution, although TAA helps just a little. SMAA and FXAA have no effect. It appears very strong on foliage, but its also present on ground textures.
(You must turn on 1080p to see it. I have FXAA enabled in the video.)
