@notimothylottes that looks incredible!

@TonyVladusich @troy_s and as a default no less!

I have been enjoying the recent threads by @pervognsen about instruction-level efficiency on computers over the years, so I'm going to do a brief one of my own based on some of my recent adventures.

It'll end up touching on topics that are coming up today and on some conversations I'd had some years ago.

In 2018, I wrote a cellular automaton program for the Sega Genesis (8MHz 68000 CPU), and in 2023 I wrote a version for the SNES (3-ish MHz 65816 CPU).

Arm Performance Studio 2025.3 is now out! Minor release, so no huge new features, but more usability polish and bug fixes.

Free Android profiling tools for Arm CPUs and Mali GPUs. Give it a try.

@thesolidpixel and I've been asking you for it since Mali-T760 🤣 (that's the first memory I have of us talking about it)

Code released for “Position-Normal Manifold for Efficient Glint Rendering on High-Resolution Normal Maps”

@thesolidpixel thrilled to see this coming out!

@TartanLlama Yes it is! Thanks Sy for putting all the tremendous work that goes into making a book like this one. This is especially true for a topic such as this one where aren't many books available and info is normally scattered around the web

The SIGGRAPH Physically Based Shading course is back this year: https://blog.selfshadow.com/publications/s2025-shading-course/

Supermarket wouldn't let me buy two instances of these bottles

I wrote a blog post about Blender, FBX, ufbx and similar pleasures of life: "Blender FBX importer via ufbx" https://aras-p.info/blog/2025/05/08/Blender-FBX-importer-via-ufbx/ #blender :blender:

@aras +1 for a proper blog post.
I've felt the pain of having to use the FBX SDK and that wasn't fun.
Also are you building on top of ufbx for Blender?

@echoparallax I was going to ask about that one next 🙂
PC Compo is hit and miss at Revision, I hope this was a good year

@echoparallax excellent thread!

"EON: A practical energy-preserving rough diffuse BRDF" https://jcgt.org/published/0014/01/06/ - this is "diffuse" part of OpenPBR.

Also interesting how linearly transformed cosines of Heitz et al keep on showing up in various places. That was such a seminal paper!

@superfunc it's the old "if you make something 2x faster, nice work. If you make something 10x faster then you fucked up to begin with."

@notimothylottes stil early days but from the little info I've seen, this is probably the most exciting graphics card launch in a while.
I might even end up upgrading to a 9070 XT (would be my first AMD card in more than 20 years)
