Upscalers are not everyone's cup of tea. What used to be viewed by many as a virtually free performance advantage for those prepared to sacrifice a bit of visual quality for a better frame rate has now increasingly become more of a requirement in many games for excellent performance. Developers take advantage of the tech to push hardware to its maximum in many of the latest games.
Still, there are purists who will argue that all upscalers deliver a "lesser" experience, and many will still choose to forgo those frame rate gains in favour of a non-upscaled native image. Many games now offer a choice as to which upscaling solution to use, although the end results can vary.
