And they're achieving "acceptable" frame rates and resolutions by sacrificing image quality in ways that aren't as easily quantified, so those downsides can be swept under the rug. Nobody's graphics benchmark emits metrics for how much ghosting is caused by the temporal antialiasing, or how much blurring the RT denoiser causes (or how much noise makes it past the denoiser). But they make for great static screenshots.
