TAA can be fine when implemented well. Temporal information can be very useful for adding more detail over multiple frames that couldn’t be obtained without doing more samples every frame.
However, when done poorly it makes things blurry as you move the camera. The information needs to be correctly adjusted for camera movements or it smears all over the screen. It’s also made worse with things like rain drop effects and things like that.
TAA is useful. It’s just too many games just enable it and it without knowing how to use it well and it just degrades the image.
It’ll never be perfect, but it can help, especially in slower paced games, or games where most of what you see is very far away (so it moves slowly on screen).
Why the hate against TAA?

Do you have an example of a game using TAA correctly? Because so far, all the games I’ve played with TAA on are blurry.
Not necessarily, no. I watched this interview with one of the Squad devs recently, and he did a really good explanation of it though, if you want to hear it.

It’s completely shit, it’s like covering your monitor in vaseline. All games with deferred rendering should use SMAA.
