RISC-V is inevitable.

Pretty amazing work!

Work like this highlights how different the compute models are between gpu and cpu. Honestly very impressed it runs as fast as it does (250khz) given those differences.

As someone who had a brief alternate life in VRC and made worlds - just /wow/. I had just enough grasp on Unity to make some basic things, but stuffing Linux into a pixel shader is 1 if not 2 orders of magnitude more impressive.

p.s. Udon Bird Sanctuary! I've been there!

It's a big differentiator with horizon worlds I think. They have an in world builder so you don't have to learn unity.

On the other hand horizon is super restricted in what you can do, is way too heavily moderated and rubber tiled so it's not fun to be in there at all. VRChat is way better at finding the edge of what's possible. I've seen whole worlds from half Life 2 recreated etc.

Article should probably have "(2021)" in the title.

Would make it a lot more impressive.
