Despite enjoying your idea, I probably won't do that, but certainly anyone who actually has this same problem should reach out to me and I'll put them in touch with the right folks at Apple, who can share the info.

Hey everyone, it worked, I had a super productive conversation with exactly the right person on the Metal team! Thanks for helping me get Apple's attention. I didn't at all expect this amount of support. https://anukari

I attempted to preempt your question in the section of my blog post, "Why don’t you just pipeline the GPU code so that it saturates the GPU?" It's one of the less-detailed sections though so maybe you have further questions?

It's a real-time audio app, so if it falls behind real time, no audio. You get cracks, pops, and the whole thing becomes unusable. If the user is doing audio at 48 kHz, the required latency is 1/48,000 seconds per sample, or reali

1. Anukari runs up to 16 entire copies of the physics model for polyphony, so 16 * 1024 * 48K (I should update the blog post) 2. Users can arbitrarily connect objects to one another, so each object has to read connections and do processing

Thanks for the thought, unfortunately when running as a plugin Anukari is subject to whatever plist.txt the host application uses. I think that I did try that with the standalone binary at one point, but unfortunately I did not appear to ta

For anyone seeing this post a bit late: I need a bit of help from someone inside Apple who works on Metal. If you know someone, it would be great if you could connect me to them: https://news.ycombinator.com/item?id=43901619

Some folks may have seen my Show HN post for Anukari here: https://news.ycombinator.com/item?id=43873074 In that thread, the topic of macOS performance came up there. Basically Anukari works great for most people on Apple s

My RTX2080Ti (admittedly not a cheap card) supports 768 physics objects (masses) per each of 16 voices. And I think that beefier cards can do 1024. There are other limitations for performance depending on how the system is constructed, and

I really like doing deep optimization work, so probably the GPU stuff was more fun from an engineering geek perspective. But the physics was also super fun, experimenting with how to model each object, and so on. The physics is a little m

Glad to hear it. I have fun writing them, often I find it's a great way to clarify my thoughts even just for me. But also I enjoy reading other people's devlogs so am glad to contribute. :)

This is a long story, which is still ongoing. The GPU code is very, very heavily optimized (though I do still have some ideas on how to go further). The main problem we're having on Mac hardware is that the OS heuristics for when to

Honestly I just haven't given wind models much thought yet! Long-term once it's stable and fast everywhere, I look forward to adding more physics features, and this is the kind of thing I'd love to look into.

Yep! I can confirm everything mutagen said. Presets are portable between mac and windows for sure.
