This question was inspired by my hatred of Temporal Anti-Aliasing which, in many games nowadays, is poorly used as a performance bandaid. On lower resolutions it will smudge and blur the image and certain bad cases of TAA will cause visible ghosting.
Yet in spite of all this, certain games won’t let you turn it off or have hair/fur/foliage look like dogshit without it so sometimes I still use it.
It being free is only barely enough incentive to use it. If they ever have effective anti-adblock and force users to watch five ads before every video, I’m gone. I will never give any money to a monopolistic company if I don’t have to.
