Deliberately stayed out the thread to see first page reactions.
They did not disappoint.
Great port and it's not even particularly optimized to push Switch 2 to its limits. The PS5 version still obviously looks better, but I did notice some skin texture gradations in Switch 2 footage that doesn't seem present elsewhere. Could be due to color space differences in hardware and some post-processing.
Crazy how Switch 2 version is at worst on par with Series S, and better in some other areas. I remember when a lot of people were saying that wouldn't be possible even when docked. Guess reality is setting in for 'em
Well in terms of pure horsepower yes the Switch 2 CPU is weaker than that of the consoles. But it being "very bad" is kind of contextual. RISC-based CPUs have simpler instructions and load-store architectures than x86 (CISC) processors, and they don't spend cycles on branch prediction (because they don't have that built into the processor). Because of that they can usually run at higher clocks than an equivalent CISC chip while also consuming less power.
So clearly, they have advantages over x86 processors, and whether they perform as sufficiently or not depends on how code is optimized for the chip. You also have to remember, Switch 2 specifically has dedicated hardware for image upscaling (and technically, the Tensor cores can also be used for other AI-driven tasks). Console-wise the only other console with dedicated hardware for upscaling is the PS5 Pro.
Generally speaking, at least when compared to Series S, if both were targeting the same output resolution and framerate, and same general visuals feature set (including RT and image upscaling), the Switch 2 has the advantage. Series S can use its more powerful CPU to try doing certain upscaling and RT tasks in software but it'll be much less efficient that way. What's more, Series S has less RAM and its RAM is technically split into two pools whereas Switch 2 has more RAM that is fully unified.
At the very least, unless talking a poorly optimized port or a game with heavy reliance on x86 instructions that don't have RISC equivalents (or the RISC equivalents require many more cycles to execute), it's reasonable to expect Switch 2 to perform at Series S levels or somewhat better when docked. Undocked is a whole other ballgame, but that's not the subject here.
TBF...SF6 is not pushing the PS5 to its limits. Also fighting games in general are generally not too taxing on hardware performance unless you're cranking the resolutions up to mad amounts.
Or at least it's been that way for the past several generations. I think the last time fighters were visual showcases to push a hardware was PS1/Saturn and arguably OG Xbox with DOA3 & Ultimate.
