In other games, DLSS2 looks better to me, but the difference is mostly apparent at high scaling factors (like the "performance" preset).
...And I briefly launched Starfield just because it came with my CPU, and to be blunt, it looks hilariously dated, and runs like a pig. Cyberpunk 2077 looks better on my laptop 2060 than Starfield does on my desktop 3090, at about the same framerate on a 4K TV. The resemblance to Oblivion is uncanny.
Don't get me wrong, I love the old BGS games and don't really care about their dated visuals, I'm just saying Starfield is a horrible test for upscaling technology.
