I'm one of those people that uses DLSS, because I've got a large fancy 4k monitor that is big enough that is looks like shit at lower resolutions.
DLSS is better than nothing but it's no replacement for native rendering, it introduces a heap of visual anomalies and inconsistencies, especially in games with a consistent motion (racing games look like shit with DLSS), so I tend to be having lows of 50fps on medium before I'll even think about DLSS.
I'm also pretty sure Nvidia is paying devs to have it on by default, because everytime it's patched into a game they clear all the current graphics settings to turn on DLSS, at least in my experience.
And not to mention it was water ingress into the bloody batteries, they're lucky (or maybe unlucky in this case) that the car didn't burn down from the Lithium...
