So I bit the bullet and bought Cyberpunk 2077 on sale for PC just to try on my Nvidia 30 series laptop just to see how good Ultra Performance DLSS (the most extreme version of DLSS they have) is at the really low resolutions. I just wanted to get a sense of "is this playable, or it this a jaggy, shimmery mess"? I'm just focusing on if the image quality is good, no Youtube video compression or artifacts.
At 2560x1440p DLSS (native res 853x480) ... honestly this is good enough for a large display. I was playing on a 15 inch 4K display and also a 27 inch monitor and it looked good on both displays ... I'll be honest, this to me would be good enough for a docked mode let alone undocked. Is it as good as native image quality? No, but I don't think average joe consumer really is going to care much. It doesn't scream out "holy shit this image it totally a 480p fugly ass image upscaled with all kinds of artifacting compromises!" the way I was sort of fearing.
For shits n' giggles I tried the 1280x720 DLSS (native res is like 240p, so lower than some N64 games lol) ... I mean ... it's playable but it looks like one of the low-res Switch 1 games. That's where it starts to get noticable when you drop below 360p native.
But from 360p it starts to really look pretty OK, and 480p is fine. My laptop is able to run Cyberpunk with ray tracing at the highest setting and all effects set to high and still gets about 45 fps, very playable on Ultra Performance DLSS @ 2560x1440 with both ray tracing lighting AND shadows. The PS5 can't do ray tracing lighting at all (only shadows). Pretty wild.
I'm impressed. Is it magic? No, but it is impressive from how low of a resolution this can go and produce a passable image quality. I'd honestly be completely ok with 360p undocked/480p docked (1080p/1440p upscaled) resolutions for "impossible ports" on Switch 2, it looks way better than the "impossible ports" on the current Switch.
