Also as a person that grew up when game consoles could connect to the TV via an RF Switch, the image-damaging effects of Temporal Anti Alias smearing are extremely visible, and NOT a “miserable invisible miniscule artifact.” They’re massive on the screen. The particular examples shown in this video do not show it particularly well because it only focuses on raytracing, but the effects of TAA are still visible because turning on raytracing almost always forces on TAA, since the low resolution raytracing benefits from the smearing TAA causes.

Here is a video that goes into way better detail about this problem, watch it and see if you still feel the same.
