>It's because the PS1 was a hunk of shit that couldn't properly map textures. The reason N64 games look so much better in this regard is because it can actually fully map textures to polygons.
It's because the PSX didn't have an FPU (the N64 was the first major console with one) to rapidly do division math. I think it's still dishonest to say that N64 games "look so much better" at textures though, they were way lower-res and blurred a lot in an unusual 3-point filter. There's a give and take between "defined detail, incorrect perspective" and "muddy-looking, correct perspective".

The wobbly vertices were bad but not the main most noticable problem, it was this. The lack of ability to have or efficiently perform float math basically caused both issues, and it applied to both the Saturn and PSX. I'm kinda shocked they decided to do a 3D console with no float math, that sounds crazy to have done even then.

Anyway I was talking about the N64's texture filtering in my post if you're referring to that. Wholly 2D games where 3D capability didn't matter did look kinda bad with it as a result, which is an unfortunate weakness for a stronger system to have.

u can tell who didint have a 64 growing up just by reading this thread

Do you have others images or videos comparison between the N64, Saturn and Playstation ?

>That's being done in hardware -- it literally costs the N64 nothing to do it.
Not true, some effects like trilinear filtering require two passes. Anti-aliasing on the other hand doubles memory bandwidth usage.

But what is really meant is stuff like pic related. Perspective correction requires extra calculations during the triangle setup stage...it's hardly free.

Similar but not identical reasons to PS1

Both consoles will zigzag because they don't divide by z when they texture map. It's as simple as that. In my experience there's slightly less zigzag on Saturn though.

>Tech-wise N64 was a bit better.
A bit better? Its CPU is 3 times faster than the one on PS1. Its vector unit (RSP) is almost 8 times faster than the one on PS1 (GTE)

PS1's GPU can deliver a fill rate of 33 MPixel/s low quality pixels.
N64's GPU can deliver a fill rate of 61.5 MPixel/s with pixels that are sub-pixel precise, z-buffered, perspective-correct textured, bilinear filtered, and anti-aliased.

Most people underestimate how much extra computation has to go into N64's higher image quality.

The N64 also has the option of doing it the PS1 way but no released game ever did.

pretty much everything else is 3D though, except maybe the sometimes dodgy z poly sort
