Hmm, I got RTX 3090, G-sync 4K and all ESO settings on max. DLAA. Got microstuttering or blur/vibration now and then. See it in the background. The “spires” or spikes on the towers in Mournhold square are “microstuttering” for example, when seen from a distance. But objects closer to me are (usually) not doing this, unless I get a fps drop from steady 100 to 99 for example. (Yes, on 4K you notice 1 fps drop.) But sometimes I also get “microstuttering” when the fps is steady 100 when using the mouse. Keyboard movement is always fine.
By the way, I have my system set to 120 Hz, and the ESO fps counter used to show a steady 116 (not 120 or 119 for some reason) but since a few weeks ago the fps counter has been a steady 100 (or 99/98), never above 100. It seems like I’ve lost 16 fps. Any idea why?
