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.
Surprisingly hard for people to accept, if you don't have it.
I really wish I could get out of using WhatsApp, but it's all everyone ever uses.
And there just isn't any good enough argument you can use to convince the average user from doing otherwise. Unless it literally makes the phone explode in your hands, people will not change.
I didn't have it for ages but it just resulted in people "texting" me and me never getting it because they actually sent me a WhatsApp
