The thing with DLSS though, is that with the original implementation, other, more traditional forms of upscaling combined with sharpening were proven to actually look and/or perform notably better, with the feature's only advantage being that it was an easy 1-click toggle to boost performance at the expense of quality in the few games that supported it.
DLSS 2.0 may have improved, and might even be a little better than those other forms of upscaling with sharpening, but that doesn't mean those other methods are any less relevant. Especially at higher resolutions, where these upscaling techniques make the most sense, people will likely be hard-pressed to notice any pixel-level differences between them while gaming, as long as they don't effectively put a blur-filter over everything like some early DLSS implementations did.
So all AMD really needs to have is a more convenient way to enable upscaling with their advanced sharpening filter. Deciding on a resolution for upscaling and where to set a slider for sharpening might be more flexible, but it is less convenient than Nvidia's 1-click solution, where the feature can either be flipped on and off, or set to a few different pre-defined quality levels in a supported game. And really, there's no reason that such an in-game "upscaling" toggle needs to be a proprietary option, supporting only one line of graphics cards. Developers are likely getting paid by Nvidia to implement DLSS, but there's no reason they couldn't get roughly similar results using other upscaling techniques that can work across all hardware. AMD just really needs to push their own DLSS-alternative toggle, and encourage developers to implement it in games. Or alternately, add a driver-level feature with a few simple quality presets that performs the upscaling and sharpening on a per-game basis in one simple step.
It looks like AMD's FidelityFX CAS feature serves to do that, though it's apparently not implemented in many games yet. And while quality might not always be quite as good as DLSS 2.0, in at least some cases it can apparently be better, as suggested in the comparison in this review for Death Stranding...

As for benchmarking games with DLSS, it seems a bit questionable unless the competition's upscaling and sharpening alternatives are also tested, even if that requires going into a graphics card profile and fiddling with sliders to enable. Realistically, I suspect the quality and performance of AMD's solution should be reasonably close, based on prior comparisons. That also introduces some vagueness as to just what constitutes an equivalent level of quality and performance in a particular game though.
