#gpc2025 was great! Met a lot of folks who I haven't seen in decades, or only know them from the internet, or haven't known them at all! I was a bit scared that after a decade out of rendering, everything would be way over my head, but turns out I could follow along just fine.

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.

I'd like to know GPU times for each of 5 buttons, with&without compute shader checkbox, and the GPU model. My own numbers at the bottom of the page.

Apple WWDC is happening, so: 20 years ago at WWDC Unity 1.0 has launched. I think it did have a massive effect of the whole game development! Also, 20 years in games tech is a really long time. #unity

While removing this 2000 lines of code, I learned that Blender has a "FELINE" texture sampling filter, which unfortunately has nothing to do with 😻 and just means "fast elliptical lines". Anyway, it is now gone since it was unused for years. projects.blender.org/blender/blen...
