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 wonβt let you turn it off or have hair/fur/foliage look like dogshit without it so sometimes I still use it.
Some people hate it just because they want to feel superior. They want FOSS but there is no FOSS that comes close to excel.
