extremely, based on the testing by gamersnexus and hardware unboxed. even a 4090 can only get you 90-100 fps on ultra without upscaling (of which only fsr 2 is present, which is generally horrible in terms of image quality). performance drops off accordingly, if i’m not mistaken you have to drop to medium on a 3060 to get 60fps at a render resolution of 1080p.
based on the numbers we’ve seen, i wouldn’t recommend high settings on anything but a 40-series, on which you probably want both dlss and framegen (for which you’ll have to install a mod, thankfully those are already out). the combination of those two gives you a clean doubling in performance, although latency doesn’t improve compared to native rendering. on older nvidia cards, you’re stuck with regular dlss, and scaling down render resolution unfortunately doesn’t have anywhere near as pronounced of an effect on nvidia as it should be based on current testing.
amd cards have anomalously high performance in this game (which is kinda sus tbh), they generally perform on par with the nvidia gpu a tier above them (so an amd gpu that normally matches the 3060 would perform like the 3070 in starfield – or rather, given the lackluster visual quality, the 3070’s performance is currently pushed down to the 3060’s level, while amd is unaffected by this). there is also no raytracing in the game yet (even though we know they worked on it because they hired for that role, and because it’s 2023) so at the moment if you have an amd card you’ll have a great time in starfield, performance doesn’t suffer the same limitations, and the technologies you would miss out on aren’t implemented yet.
on the intel side, however, the game doesn’t run at all. most of the time you won’t even get to the menu, and if you do, rendering is completely borked. it is unclear yet if the issue is with bethesda or intel, but given that it’s an amd-sponsored game, the charitable interpretation is that they didn’t test on intel hardware at all or give intel any time to fix stuff, and the less charitable interpretation is that they’re intentionally locking out intel cards.
