Maybe not stuff to best the likes of FF VIII or IX, Parasite Eve 2 or GT2, but closer to those results than some would maybe expect. I agree though with all of the architecture drawbacks you mention; those existed and compounded on Saturn's problems and lack of a decent SDK for so long just exacerbated the issues (the website with that screencap is a fantastic source on these systems, too).
I can concede on all you just said, but I'll still maintain that it's by far the weakest platform
Yep, I also think PS2 might have had higher polygon culling or rasterization rate than the GC and Xbox as well, but I'm not sure on that. While it didn't have shader support like the GC and Xbox, it had something with "texture layers" or something like that (again trying to recall from what I've read, it's been a minute) and programmers could use that to effectively simulate something similar to shaders, if a bit less efficient.
Not really less efficient. You could draw six layers, maybe even more, at minimal to no cost due to the absurd bandwidth (If I'm not mistaken). It was not as "good" in most cases, but it allowed for some pretty groundbreaking effects that even the PS3 had difficulty pulling off (mostly due to higher target resolution though, but still very impressive).
One of the things that sucked with PS2 though was its limited video output support. Even if it could have produced higher resolution in certain games over GC & Xbox, it had a video output with more muted colors and softening of the image than GC, Xbox and DC. Would've been nice if Sony went a bit further in that respect but considering all the other tech packed into the system, it wasn't a bad tradeoff.
Yeah... Games looked a bit muddy overall. Shit, I just realised we're moving to the 6th gen already hahaha.
Explains a lot why Final Fight Revenge became such a kusoge game. Granted, I don't think Saturn ports of RE1 would have exactly matched up with the PS1's if Capcom handled it in-house, outside of the backgrounds which may've been better (and maybe the FMVs and CG sequences if they programmed support for the MPEG decoder card...though how many Saturn owners would have actually bothered with that?), but I think they'd of been a bit better and closer to matching the PS1 versions than they did.
One of the things you can really notice is how jagged the models look on the Saturn version due to the use of quadrilaterals.
