Currently there are some titles on PC that support "Dynamic Resolution Scaling" (Titanfall 2 for example). What this does exactly is covered here by Digital Foundry here: where they talk about a recent mod that unlocks DRS from the console versions of the DOOM 2016 on PC with some very interesting results. One thing I'd be very curious to see is "Dynamic Resolution Scaling" combined with Nvidia's "Deep Learning Super Sampling" (which has reportedly been dramatically improved in its latest release in Wolfenstein Young Blood). This could be especially interesting for users who would rather vary the image resolution than the framerate/users who are targeting a specific framerate where presently DLSS only works off a static resolution that never varies with load. So, for example, of course DOOM 2016 does not have DLSS support (though DOOM Eternal likely will), but imagine you as a user are attemping what Alex is attempting in that DF video linked above where you want a locked 60 fps on midrange hardware with your high resolution monitor. DRS can get you there, but you all it does is standard/traditional upscaling -- instead, one could theoretically "upgrade" that upscaling to image reconstruction like DLSS. Would be really interesting to test/see results for I think.
