You'd be surprised what some of these guys can do. Check out a rom hack of Aria of Sorrow called Serenade of the night. It straight up uses the ps1 music and the quality is immaculate.

[@IntegerOfDoom]

Nintendo really fucked up not providing proper audio hardware.

[@3dmarth]

From what I understand, the GBA can output directly to two PCM channels with minimal performance penalty- as seen here- but the main issue is when devs try to do software mixing to get around that limitation: playing multiple sound effects and instruments at the same time, and then combining them into a single channel on the fly. That chews up a lot of CPU time, and it gets worse as more sounds are added or higher quality audio is used. Making a recording of the N64 music and effectively "streaming" it (breaking it into chunks, or samples, and playing through those in order) ensures that the music only takes one channel. If one channel is used for music, and one is used for sounds, then no soft mixing is needed. The downside is that the music will take up a ton of space, as the GBA can't effectively handle good audio compression (or at least not without taxing the CPU hard)! See also: F-Zero X. The N64 had similar issues around audio, and FZX's streamed music (mono ADPCM) was very fast to play back, leaving more time for the RSP to push thousands of polygons around at 60fps.

[@JeffACornell]

Fantastic! The textures look great! Like you said, before, the warping near the camera was a major eyesore, but now you've got it reduced to something easily tolerable and even a little charming. A texture that's obviously supposed to be a nice grid, like the tiled floor in the castle, still stands out as looking obviously wrong. But that's a minor nitpick, and easily resolved by just giving the floor a different texture that's less of a perfect grid.

[@ArneChristianRosenfeldt]

PlayStation 1 used fixed size bins, which are faster. Variable size needs a tree search. Can do quicksort in the same time. 2:40

[@jsbarretto]

Yep, exactly. ~1000 is few enough that skipping through the empty ones isn't a huge performance hog, but also high enough that draw order irregularities are pretty rare. Another advantage of subdivision that I didn't mention in the video is that subdivision occurs before depth sorting, so the subdivided triangles end up getting sorted into the depth bins independently, resulting in even fewer depth issues.

[@ArneChristianRosenfeldt]

@@jsbarrettoI thought that psx only sorts z by bin? Inside each bin Sony uses a linked list, which would be pretty slow to sort. The easy structure of a z buffer makes it fast. Even a hierarchical buffer doesn’t need malloc. Would be interesting to benchmark it at this low resolution. Correction: quicksort works well on a linked list. As separating value start with the middle of the bin. Needs to be double linked or seek for center first? We need links anyway for the triangle structure. Still sorting array of z:id sounds faster to me

[@MatthewCenance]

4:50 How do you avoid performance issues by subdividing the polygons? It seems like it would slash rendering performance if you render two to three time the triangles or more for closer objects!

[@jsbarretto]

I put some work in to radically reduce the overhead of triangle drawing. This means that triangle drawing time is now largely dominated by texture mapping, which is a reasonable tradeoff because subdivided polygons are smaller anyway and so require less texture mapping work. Also, subdivided polygons don't need to go through vertex transformation to view space: I can just pick a point halfway between the parent polygon vertices to use as the new vertex. This also saves a lot of processing time. All that aside, it definitely does have a performance impact. It's a bit difficult to quantify just how much since implementing it required changing other aspects of the rendering code too, but disabling it looks to produce a roughly 5-10% speedup. That's sufficiently low that I don't think that having it enabled by default is an issue though.

[@MatthewCenance]

@@jsbarretto So this is how games have so many divided triangles on the PS1 to combat the texture warping and distortion without destroying the performance?

[@jsbarretto]

@@MatthewCenance Yes. I think PS1 games do this subdivision in software so I imagine many of them use different approaches. I don't know exactly how they work, this is very much my own spin on how I personally think it should be implemented.
