Not 100% yet, but Metal is getting there! Still need to work out some push constant and barrier nonsense.

The choice is impeachment and removal or calamity for the United States. I don't see how anybody watching Trump's speech in Davos can draw any other conclusion. He's a senile madman.

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.

Just fuck you. Fuck you all.

I can't remember the last time I was this angry.

Happy holidays!

Much of the Marathon team is taking time to enjoy the holidays, but this week we applied upstream fixes for D3D12 and removed a patch that caused severe problems with cutscenes.

I highly recommend reading Sebastian Aaltonen's blog post, which basically has everything I could ever want from a modern graphics API. Let's hope vendors actually listen.

Initial stage rendering in XNOEdit! Making progress towards accurate rendering...
November 28, 2025 at 11:20 PM
This week, I made a bunch of progress on XNOEdit, my cross-platform editor/viewer for Sonic '06 objects powered by .NET and WGPU.

Still lots to do, but many objects now correctly visualise, including textures! Next up, bringing in original recompiled shaders so everything looks perfect.

Sometimes, computer graphics can result in horrors beyond your comprehension
November 18, 2025 at 3:59 AM
Been a bit since I've done a weekly update, so here's what we're up to! Lots of stuff is in the works:

- Achievement support (Hyper)
- Physics-based high FPS fixes and APIs for character controllers (Rei)
- MSAA & resize support (Rei & I)
- External cross-platform XNO editor (Me)

Stay tuned!

THAR SHE BLOWS 🐋 🫧
Huge scoop from Ed, who had several years of financial reports leaked to him. OpenAI has been over-reporting their revenue. The company is even less profitable than we knew.
Exclusive: Based on documents viewed by this newsletter, OpenAI spent over $12.4 billion on inference from 2024 to September 2025. As part of its Microsoft revenue share, it sent $493.8m in 2024/$865.8m Jan-Sep 2025, implying lower revenues than previously reported.
